组件一导出到Excel文件

我试图导出使用C1 Excel的提示，以保存文件的用户。 不过，我已经尝试了下面的代码，但似乎并没有工作。

Response.Clear(); Response.ContentType = "application/vnd.ms-excel"; Response.AppendHeader("Content-Disposition","attachment;filename=CategoryReport.xls"); System.IO.MemoryStream ms = new System.IO.MemoryStream(); xbook.Save(ms, C1.C1Excel.FileFormat.Biff8); ms.WriteTo(Response.OutputStream); ms.Close(); ms.Dispose(); xbook.Dispose(); 

请帮忙=）

您可以使用HTTP处理程序（DownloadFile.ashx）：

 public class DownloadFile : IHttpHandler { public void ProcessRequest(HttpContext context) { // retrieve your xbook System.IO.MemoryStream ms = new System.IO.MemoryStream(); xbook.Save(ms, C1.C1Excel.FileFormat.Biff8); xbook.Dispose(); ms.Position = 0; System.Web.HttpResponse response = System.Web.HttpContext.Current.Response; response.ClearContent(); response.Clear(); response.ContentType = "application/vnd.ms-excel"; response.AddHeader("Content-Disposition","attachment;filename=CategoryReport.xls"); Response.BufferOutput = true; Response.OutputStream.Write(ms.ToArray(), 0, (int)ms.Length); response.Flush(); response.End(); } public bool IsReusable { get { return false; } } 

}

在代码后面的导出事件中：

  Response.Redirect("YourPathToHttpHandler/DownloadFile.ashx");
