我正在使用 ExportToExcel dll。在第一次迭代中，我的数据集包含以下记录

KeyName English Hindi
Name    engval  hival

And second iteration my dataset conatin below record

KeyName English Hindi
Name    engval  hival

我必须在运行时一一创建 xsl 文件，如下所示。如何在其上应用看起来不错的样式。

hindi.xsl    

KeyName English Hindi
Name    engval  hival

punjabi.xsl

KeyName English panjabi
Name    engval  punjabival

编辑：使用 GridViewExportUtil

我正在尝试一个一个地创建 xsl。下面是我的逻辑

for(int i=0;i<2;i++)
{   

//

****logic here to get the record from db and fill the record into dsexcel***

//
gvruntime.DataSource = dsExcel;
gvruntime.DataBind();
string headername = string.Empty;
headername = i+".xls";
GridViewExportUtil.Export(headername, this.gvruntime);  
}

在这种情况下，只有最后一个文件与前一个文件相比..请告诉我如何解决它

请试试这段代码，这段代码会将gridview数据导出到excel。您需要先将数据集绑定到 gridview 然后调用此函数

     GridViewExportUtil.Export("hindi.xsl", this.grdhindi);
     GridViewExportUtil.Export("punjabi.xsl", this.grdpunjabi);


// calss code
  public class GridViewExportUtil
    {
        /// <summary>
        /// 
        /// </summary>
        /// <param name="fileName"></param>
        /// <param name="gv"></param>
        public static void Export(string fileName, GridView gv)
        {
            HttpContext.Current.Response.Clear();
            HttpContext.Current.Response.ClearHeaders();
            HttpContext.Current.Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", fileName));
            //HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
            HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.Private);
            HttpContext.Current.Response.ContentType = "application/ms-excel";

            using (StringWriter sw = new StringWriter())
            {
                using (HtmlTextWriter htw = new HtmlTextWriter(sw))
                {
                    //  Create a form to contain the grid
                    Table table = new Table();

                    table.GridLines = gv.GridLines;

                    //  add the header row to the table
                    if (gv.HeaderRow != null)
                    {
                        //gv.HeaderRow.Font.Bold = true;
                        GridViewExportUtil.PrepareControlForExport(gv.HeaderRow);
                        table.Rows.Add(gv.HeaderRow);
                    }

                    //  add each of the data rows to the table
                    foreach (GridViewRow row in gv.Rows)
                    {
                        GridViewExportUtil.PrepareControlForExport(row);
                        table.Rows.Add(row);
                    }

                    //  add the footer row to the table
                    if (gv.FooterRow != null)
                    {
                        GridViewExportUtil.PrepareControlForExport(gv.FooterRow);
                        table.Rows.Add(gv.FooterRow);
                    }

                    //  render the table into the htmlwriter
                    table.RenderControl(htw);

                    byte[] s = Encoding.UTF8.GetBytes(sw.ToString());
                    HttpContext.Current.Response.AddHeader("Content-Length", s.Length.ToString());
                    HttpContext.Current.Response.BinaryWrite(s);

                    //  render the htmlwriter into the response
                    HttpContext.Current.Response.Write(sw.ToString());
                    HttpContext.Current.Response.End();
                }
            }
        }

        /// <summary>
        /// Replace any of the contained controls with literals
        /// </summary>
        /// <param name="control"></param>
        private static void PrepareControlForExport(Control control)
        {
            for (int i = 0; i < control.Controls.Count; i++)
            {
                Control current = control.Controls[i];
                if (current is LinkButton)
                {
                    control.Controls.Remove(current);
                    control.Controls.AddAt(i, new LiteralControl((current as LinkButton).Text));
                }
                else if (current is ImageButton)
                {
                    control.Controls.Remove(current);
                    control.Controls.AddAt(i, new LiteralControl((current as ImageButton).AlternateText));
                }
                else if (current is HyperLink)
                {
                    control.Controls.Remove(current);
                    control.Controls.AddAt(i, new LiteralControl((current as HyperLink).Text));
                }
                else if (current is DropDownList)
                {
                    control.Controls.Remove(current);
                    control.Controls.AddAt(i, new LiteralControl((current as DropDownList).SelectedItem.Text));
                }
                else if (current is CheckBox)
                {
                    control.Controls.Remove(current);
                    control.Controls.AddAt(i, new LiteralControl((current as CheckBox).Checked ? "True" : "False"));
                }

                if (current.HasControls())
                {
                    GridViewExportUtil.PrepareControlForExport(current);
                }
            }
        }
    }

或者您可以使用不同的方式将网格数据导出到 excel

 for(int i=0;i<2;i++)
    {   


    gvruntime.DataSource = dsExcel.Table[i];
    gvruntime.DataBind();
    string headername = string.Empty;
    headername = i+".xls";


 // render the DataGrid control to a file
    using(StreamWriter sw = new StreamWriter("c:\\"+headername+".xls"))
    {
        using(HtmlTextWriter hw = new HtmlTextWriter(sw))
        {
            gvruntime.RenderControl(hw);
        }
    } 

    }
