第2篇： asp.net中将DataGrid中的数据导入到excel中，并设置其格式

----------------------------------------------------------------------------

终于完成了从datagrid 中导入excel，为了防止忘记，特意记录下来，为大家和自己提供方便。

web应用程序中主要代码如下：

view plaincopy to clipboardprint?
//设置DataGrid2数据源，并绑定（由于这一步很简单，所以略过）

/**//*设置DataGrid2的格式为文本型，这样就解决了导入excel之后，形如“00000123”变成了“123”的问题。在这里，为了简单起见，我设置了dataGrid总的属性。也可以为每个单元格设置属性，如DataGrid2.Items[0].Cells[0].Attributes.Add("style","vnd.ms-excel.numberformat:@");*/
DataGrid2.Attributes.Add("style","vnd.ms-excel.numberformat:@");

//将DataGrid2中的数据以流的形式写入excel文件中

Response.Clear();    
Response.Buffer= true;    
Response.Charset="GB2312";   
Response.AppendHeader("Content-Disposition","attachment;filename=zjxx.xls");    
Response.ContentEncoding=System.Text.Encoding.GetEncoding("GB2312");//设置输出流为简体中文   
Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。    
this.EnableViewState = false;       
System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN",true);   
System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad);    
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);   
this.DataGrid2.RenderControl(oHtmlTextWriter);   
Response.Write(oStringWriter.ToString());   
Response.End();

//设置DataGrid2数据源，并绑定（由于这一步很简单，所以略过）

/**//*设置DataGrid2的格式为文本型，这样就解决了导入excel之后，形如“00000123”变成了“123”的问题。在这里，为了简单起见，我设置了dataGrid总的属性。也可以为每个单元格设置属性，如DataGrid2.Items[0].Cells[0].Attributes.Add("style","vnd.ms-excel.numberformat:@");*/
DataGrid2.Attributes.Add("style","vnd.ms-excel.numberformat:@");

//将DataGrid2中的数据以刘的形式写入excel文件中

Response.Clear(); 
Response.Buffer= true; 
Response.Charset="GB2312";
Response.AppendHeader("Content-Disposition","attachment;filename=zjxx.xls"); 
Response.ContentEncoding=System.Text.Encoding.GetEncoding("GB2312");//设置输出流为简体中文
Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。 
this.EnableViewState = false;    
System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN",true);
System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad); 
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
this.DataGrid2.RenderControl(oHtmlTextWriter);
Response.Write(oStringWriter.ToString());
Response.End();

windows应用程序中如下：

//其中zjtable中已经从数据库中读入了数据   
Excel.ApplicationClass excelApp ;   
excelApp = new Excel.ApplicationClass();   
Excel.Workbook excelBook =excelApp.Workbooks.Add(1);   
Excel.Worksheet excelSheet=(Excel.Worksheet)excelBook.Worksheets[1];   
  
excelApp.Visible=true;   
excelSheet.Cells[1,1]="姓名";   
excelSheet.Cells[1,2]="性别";   
excelSheet.Cells[1,3]="出生日期";   
  
//设置excel文件中所有的单元格为文本型   
excelSheet.Cells.NumberFormatLocal="@";   
for(int i=0;i < zjtable.Rows.Count  ;i++)   
...{   
//将zjtable中的数据导入到excel文件中   
    DataRow row=zjtable.Rows[i];   
    for (int j=1;j<=3;j++)   
                          excelSheet.Cells[i+2,j]=row[j].ToString();   
}  
//其中zjtable中已经从数据库中读入了数据
Excel.ApplicationClass excelApp ;
excelApp = new Excel.ApplicationClass();
Excel.Workbook excelBook =excelApp.Workbooks.Add(1);
Excel.Worksheet excelSheet=(Excel.Worksheet)excelBook.Worksheets[1];
excelApp.Visible=true;
excelSheet.Cells[1,1]="姓名";
excelSheet.Cells[1,2]="性别";
excelSheet.Cells[1,3]="出生日期";
//设置excel文件中所有的单元格为文本型
excelSheet.Cells.NumberFormatLocal="@";
for(int i=0;i < zjtable.Rows.Count  ;i++)
...{
//将zjtable中的数据导入到excel文件中
    DataRow row=zjtable.Rows[i];
    for (int j=1;j<=3;j++)
                          excelSheet.Cells[i+2,j]=row[j].ToString();
}

第3篇： asp.net中将DataTable中的数据导出到excel中，并设置其格式【中间件】

----------------------------------------------------------------------------

中間包xml格式
下面是一個ExcelExporter.cs檔，我用一個物件去參考它後，用裡面的Export(DataSet, ExcelFileName)就可以跳出另存新檔的視窗！
就可以順利存成Excel檔了！

我要如何像之前的文章中所做的一樣，像加下面這一行，就可以在Excel中正常顯示！
依照我提供的Code要加在哪？？我試好久摟，東塞西塞也沒用！>,<"...
this.page.Response.Write( "<style>Data { mso-number-format:"\@"; } </style>" );
這一段直接全部Copy就可以用了！
