c#WinForm程序将DataGridView数据写入WORD文档问题！
我想把DataGridView中的数据导出到一个WORD文档 在文档中创立一个Table 然后为table的每个单元格写值 行是行 但是速度实在是太慢了 100多行的数据 跑的CPU都到100%了 希望高手帮忙搞定下！

C# code

        /// <summary>        /// 导出Word        /// </summary>        /// <param name="dt">导出的数据DataTable</param>        /// <param name="isColname">是否显示列名</param>        public static void OutPutWordDT(DataTable dt, bool isColname)        {            Object Nothing = System.Reflection.Missing.Value;            Word.Application oword = new Word.Application();//word Application            Word.Document odoc = oword.Documents.Add(ref Nothing, ref Nothing, ref Nothing, ref Nothing);//文档            odoc.Paragraphs.Alignment = Word.WdParagraphAlignment.wdAlignParagraphCenter;                       try            {                //在word以表格形式存储数据                Word.Table otable = odoc.Tables.Add(oword.Selection.Range, dt.Rows.Count + 1, dt.Columns.Count, ref Nothing, ref Nothing);                otable.Range.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphThaiJustify;//设置对其方式                otable.Borders.OutsideLineStyle = Word.WdLineStyle.wdLineStyleSingle;//设置表格边框样式                               if (isColname)//列名称                {                    int intcol = 0;                    for (int ii = 0; ii < dt.Columns.Count; ii++)                    {                        intcol += 1;                        otable.Cell(1, intcol).Range.Text = dt.Columns[ii].ColumnName;                        otable.Cell(1, intcol).Range.Borders.OutsideLineStyle = WdLineStyle.wdLineStyleSingle;//设置单元格样式                    }                }                //写表格内容                int intRow = 1;                for (int ii = 0; ii < dt.Rows.Count; ii++)                {                    intRow += 1;                    int intCol = 0;                    for (int jj = 0; jj < dt.Columns.Count; jj++)                    {                        intCol += 1;                        otable.Cell(intRow, intCol).Range.Text = dt.Rows[ii][jj].ToString();                        otable.Cell(intRow, intCol).Range.Borders.OutsideLineStyle = WdLineStyle.wdLineStyleSingle;//设置单元格样式                    }                }                oword.Visible = true;            }            catch (Exception) { }            finally            {                System.Diagnostics.Process[] CurrentProcess = System.Diagnostics.Process.GetProcessesByName("WINWORD");                for (int i = 0; i < CurrentProcess.Length; i++)                {                    if (CurrentProcess[i].MainWindowHandle.ToInt32() == 0)                    {                        try                        {                            CurrentProcess[i].Kill();                        }                        catch                        {                        }                    }                }            }        }

把datagridview的数据输出为Excel,Word的简单应用

C# code

public static void ExportData(DataGridView srcDgv,string fileName)//导出数据,传入一个datagridview和一个文件路径{string type = fileName.Substring(fileName.IndexOf(”.”)+1);//获得数据类型if (type.Equals(”xls”,StringComparison.CurrentCultureIgnoreCase))//Excel文档{Excel.Application excel = new Excel.Application();try{excel.DisplayAlerts = false;excel.Workbooks.Add(true);excel.Visible = false;for (int i = 0; i < srcDgv.Columns.Count; i++)//设置标题{excel.Cells[2, i+1] = srcDgv.Columns[i].HeaderText;}for (int i = 0; i < srcDgv.Rows.Count; i++)//填充数据{for (int j = 0; j < srcDgv.Columns.Count; j++){excel.Cells[i + 3, j + 1] = srcDgv[j, i].Value;}}excel.Workbooks[1].SaveCopyAs(fileName);//保存}finally{excel.Quit();}return;}//保存Word文件if (type.Equals(”doc”, StringComparison.CurrentCultureIgnoreCase)){object path = fileName;Object none=System.Reflection.Missing.Value;Word.Application wordApp = new Word.Application();Word.Document document = wordApp.Documents.Add(ref none, ref none, ref none, ref none);//建立表格Word.Table table= document.Tables.Add(document.Paragraphs.Last.Range, srcDgv.Rows.Count+1, srcDgv.Columns.Count, ref none, ref none);try{for (int i = 0; i < srcDgv.Columns.Count; i++)//设置标题{table.Cell(1, i + 1).Range.Text = srcDgv.Columns[i].HeaderText;}for (int i = 0; i < srcDgv.Rows.Count; i++)//填充数据{for (int j = 0; j < srcDgv.Columns.Count; j++){table.Cell(i + 2, j + 1).Range.Text = srcDgv[j, i].Value.ToString();}}document.SaveAs(ref path, ref none, ref none, ref none, ref none, ref none, ref none, ref none, ref none, ref none, ref none, ref none, ref none, ref none, ref none, ref none);document.Close(ref none, ref none, ref none);}finally{wordApp.Quit(ref none, ref none, ref none);}}}
