我用的是VS2008开发的，我电脑上安装的Excel是2007版。网上也有相关的代码，但应用到我程序中出现错误：
如导出文件名是乱码：
打开时提示错误：
我的相关代码如下：
public static void ToExcel(Control ctl, string FileName)
{
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.Charset = "GB2312";
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.Default;
HttpContext.Current.Response.ContentType = "application/ms-excel";
HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + "" + FileName+".xls");
// HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF7;
ctl.Page.EnableViewState = false;
System.IO.StringWriter tw = new System.IO.StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);
ctl.RenderControl(hw);
HttpContext.Current.Response.Output.Write(tw.ToString());
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();
}
public override void VerifyRenderingInServerForm(Control control)
{
}
帮我看看哪里有问题？大家有更适用代码的可以分享？

参考
- C# code
public static void DataTable2Excel(System.Data.DataTable dtData) { System.Web.UI.WebControls.DataGrid dgExport = null; // 当前对话 System.Web.HttpContext curContext = System.Web.HttpContext.Current; // IO用于导出并返回excel文件 System.IO.StringWriter strWriter = null; System.Web.UI.HtmlTextWriter htmlWriter = null; if (dtData != null) { // 设置编码和附件格式 curContext.Response.ContentType = "application/vnd.ms-excel"; curContext.Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312"); curContext.Response.Charset = ""; // 导出excel文件 strWriter = new System.IO.StringWriter(); htmlWriter = new System.Web.UI.HtmlTextWriter(strWriter); // 为了解决dgData中可能进行了分页的情况，需要重新定义一个无分页的DataGrid dgExport = new System.Web.UI.WebControls.DataGrid(); dgExport.DataSource = dtData.DefaultView; dgExport.AllowPaging = false; dgExport.DataBind(); // 返回客户端 dgExport.RenderControl(htmlWriter); curContext.Response.Write(strWriter.ToString()); curContext.Response.End(); } }

度娘，Myxls
你这个导出局限性太大！
