在开发中经常需要将grid中的数据导出成Excel或Word格式。下面我们来说说如何实现它：

1 先用一个方法，筛选出有效的数据。

因为grid中可能会有隐藏列，而这些列中的数据我们一般都是不需要的，所以我们先将grid中的数据进行过滤，保存在一个DataTable中。

private DataTable exporeDataToTable(DataGridView dataGridView)
        {
            //将datagridview中的数据导入到表中
            DataTable tempTable = new DataTable("tempTable");
            //定义一个模板表，专门用来获取列名
            DataTable modelTable = new DataTable("ModelTable");
            //创建列
            for (int column = 0; column < dataGridView.Columns.Count; column++)
            {
                //可见的列才显示出来
                if (dataGridView.Columns[column].Visible == true)
                {
                    DataColumn tempColumn = new DataColumn(dataGridView.Columns[column].HeaderText, typeof(string));
                    tempTable.Columns.Add(tempColumn);
                    DataColumn modelColumn = new DataColumn(dataGridView.Columns[column].Name, typeof(string));
                    modelTable.Columns.Add(modelColumn);
                }
            }
            //添加datagridview中行的数据到表
            for (int row = 0; row < dataGridView.Rows.Count; row++)
            {
                if (dataGridView.Rows[row].Visible == false)
                {
                    continue;
                }
                DataRow tempRow = tempTable.NewRow();
                for (int i = 0; i < tempTable.Columns.Count; i++)
                {
                    tempRow[i] = dataGridView.Rows[row].Cells[modelTable.Columns[i].ColumnName].Value;
                }
                tempTable.Rows.Add(tempRow);
            }
            return tempTable;
        }

2 导出为Excel。

导出Excel会用到Microsoft.Office.Interop.Excel.dll，所以必须先在项目中引用这个DLL。

private void OutputAsExcelFile(DataGridView dataGridView)
        {
            //将datagridView中的数据导出到一张表中
            DataTable tempTable = this.exporeDataToTable(dataGridView);
            //导出信息到Excel表
            Microsoft.Office.Interop.Excel.ApplicationClass myExcel;
            Microsoft.Office.Interop.Excel.Workbooks myWorkBooks;
            Microsoft.Office.Interop.Excel.Workbook myWorkBook;
            Microsoft.Office.Interop.Excel.Worksheet myWorkSheet;
            char myColumns;
            Microsoft.Office.Interop.Excel.Range myRange;
            object[,] myData = new object[500, 35];
            int i, j;//j代表行,i代表列
            myExcel = new Microsoft.Office.Interop.Excel.ApplicationClass();
            //显示EXCEL
            myExcel.Visible = true;
            if (myExcel == null)
            {
                MessageBox.Show("本地Excel程序无法启动!请检查您的Microsoft Office正确安装并能正常使用", "提示");
                return;
            }
            myWorkBooks = myExcel.Workbooks;
            myWorkBook = myWorkBooks.Add(System.Reflection.Missing.Value);
            myWorkSheet = (Microsoft.Office.Interop.Excel.Worksheet)myWorkBook.Worksheets[1];
            myColumns = (char)(tempTable.Columns.Count + 64);//设置列
            myRange = myWorkSheet.get_Range("A4", myColumns.ToString() + "5");//设置列宽
            int count = 0;
            //设置列名
            foreach (DataColumn myNewColumn in tempTable.Columns)
            {
                myData[0, count] = myNewColumn.ColumnName;
                count = count + 1;
            }
            //输出datagridview中的数据记录并放在一个二维数组中
            j = 1;
            foreach (DataRow myRow in tempTable.Rows)//循环行
            {
                for (i = 0; i < tempTable.Columns.Count; i++)//循环列
                {
                    myData[j, i] = myRow[i].ToString();
                }
                j++;
            }
            //将二维数组中的数据写到Excel中
            myRange = myRange.get_Resize(tempTable.Rows.Count + 1, tempTable.Columns.Count);//创建列和行
            myRange.Value2 = myData;
            myRange.EntireColumn.AutoFit();
        }

3 导出为Word格式

同样的，导出为Word要添加对Microsoft.Office.Interop.Word.Dll的引用。

private void OutPutAsWordFile(DataGridView dataGridView)
        {
            //转换后的表
            DataTable table = exporeDataToTable(this.dataGridView1);

            Microsoft.Office.Interop.Word.ApplicationClass wordApp = new Microsoft.Office.Interop.Word.ApplicationClass();
            Microsoft.Office.Interop.Word.Document document;
            Microsoft.Office.Interop.Word.Table wordTable;
            Microsoft.Office.Interop.Word.Selection wordSelection;
            object wordObj = System.Reflection.Missing.Value;

            document = wordApp.Documents.Add(ref wordObj, ref wordObj, ref wordObj, ref wordObj);
            wordSelection = wordApp.Selection;
            //显示word文档
            wordApp.Visible = true;
            if (wordApp == null)
            {
                MessageBox.Show("本地Word程序无法启动!请检查您的Microsoft Office正确安装并能正常使用", "提示");
                return;
            }
            document.Select();
            wordTable = document.Tables.Add(wordSelection.Range, dataGridView.Rows.Count+1, dataGridView.Columns.Count, ref wordObj, ref wordObj);
            //设置列宽
            wordTable.Columns.SetWidth(50.0F, Microsoft.Office.Interop.Word.WdRulerStyle.wdAdjustSameWidth);
            
             //标题数据
            for (int i = 0; i < table.Columns.Count; i++)
            {
                wordTable.Cell(1, i + 1).Range.InsertAfter(table.Columns[i].ColumnName);
            }
            //输出表中数据
            for (int i = 0; i <= table.Rows.Count - 1; i++)
            {
                for (int j = 0; j < table.Columns.Count; j++)
                {
                    if (table.Rows[i][j] != null)
                    {
                        wordTable.Cell(i + 2, j + 1).Range.InsertAfter(table.Rows[i][j].ToString());
                    }
                }
            }

             //画表格的行
             wordTable.Borders.InsideLineStyle = Microsoft.Office.Interop.Word.WdLineStyle.wdLineStyleSingle;
             //画表格的列
             wordTable.Borders.OutsideLineStyle = Microsoft.Office.Interop.Word.WdLineStyle.wdLineStyleSingle;

十一、上下左右移动光标位

private void moveLeft()

{

object moveUnit = Microsoft.Office.Interop.Word.WdUnits.wdWord;

object moveCount = 1;

object moveExtend = Microsoft.Office.Interop.Word.WdMovementType.wdExtend;

thisDocument.Application.Selection.MoveLeft(ref moveUnit, ref moveCount, ref MissingValue);

}

private void moveRight()

{

if(selection==null||selection!=document.Application.Selection)

selection=document.Application.Selection;

object dummy=System.Reflection.Missing.Value;

object count=1;

object Unit=Word.WdUnits.wdCharacter;

selection.MoveRight(ref Unit,ref count,ref dummy);

}

十二、取得当前光标位

public void GetCursor()

{

if(selection==null||selection!=document.Application.Selection)

selection=document.Application.Selection;

object a=selection.get_Information(Word.WdInformation.wdFirstCharacterLineNumber);

object b=selection.get_Information(Word.WdInformation.wdFirstCharacterColumnNumber);

object c=selection.get_Information(Word.WdInformation.wdActiveEndAdjustedPageNumber);

MessageBox.Show(a.ToString()+”行,”+b.ToString()+”列,”+c.ToString()+”页”);

}

十三、定位到指定行或相对行

/// <summary>

/// 定位到指定行

/// </summary>

/// <param name=”lineNum”>行号</param>

private void gotoAbsolutLine(int lineNum)

{

if(selection==null||selection!=document.Application.Selection)

selection=document.Application.Selection;

object dummy=System.Reflection.Missing.Value;

object what=Word.WdGoToItem.wdGoToLine;

object which=Word.WdGoToDirection.wdGoToFirst;

object count=lineNum;

selection.GoTo(ref what,ref which,ref count,ref dummy);

}

/// <summary>

/// 定位到相对行，例如+4

/// </summary>

/// <param name=”lineNum”>行数</param>

private void gotoOppositeLine(int lineNum)

{

if(selection==null||selection!=document.Application.Selection)

selection=document.Application.Selection;

object dummy=System.Reflection.Missing.Value;

object what=Word.WdGoToItem.wdGoToLine;

object which;

if(lineNum<0)

which=Word.WdGoToDirection.wdGoToPrevious;

else

which=Word.WdGoToDirection.wdGoToNext;

object count=Math.Abs(lineNum);

selection.GoTo(ref what,ref which,ref count,ref dummy);

}

十四、定位到文档最后一行

private void gotoLastLine(Document thisDocument)

{

object dummy = System.Reflection.Missing.Value;

object what = WdGoToItem.wdGoToLine;

object which = WdGoToDirection.wdGoToLast;

object count = 99999999;

thisDocument.Application.Selection.GoTo(ref what, ref which, ref count, ref dummy);

}

十五、定位到第一个字符

private void gotoFirstCharacter()

{

if(selection==null||selection!=document.Application.Selection)

selection=document.Application.Selection;

int oldLine=0;

gotoAbsolutLine(1);

object a=selection.get_Information(Word.WdInformation.wdFirstCharacterLineNumber);//得到当前行号

while(oldLine!=int.Parse(a.ToString()))//一直按右键，直到光标不再往下了为止

{

oldLine++;

moveRight();

a=selection.get_Information(Word.WdInformation.wdFirstCharacterLineNumber);

}

gotoAbsolutLine(int.Parse(a.ToString()));

}

十六、定位到最后一个字符

public void gotoLastCharacter()

{

if(selection==null||selection!=document.Application.Selection)

selection=document.Application.Selection;

gotoLastLine();

object dummy=System.Reflection.Missing.Value;

object count=99999999;

object Unit=Word.WdUnits.wdCharacter;

selection.MoveRight(ref Unit,ref count,ref dummy);

}

二十一、取得行、列、页信息

public string WordGetRCP()

{

selection=document.Application.Selection;//wd.Selection;

object a=selection.get_Information(Word.WdInformation.wdFirstCharacterLineNumber);

object b=selection.get_Information(Word.WdInformation.wdFirstCharacterColumnNumber);

object c=selection.get_Information(Word.WdInformation.wdActiveEndAdjustedPageNumber);

return a.ToString()+”,”+b.ToString()+”,”+c.ToString();

}
