第二次单击ASP.NET按钮时没有响应 [英] no response when I click the ASP.NET button at the second time

问题描述

有一个ASP.NET按钮，它调用以下代码。

There is an ASP.NET button which calls the following code.

Response.ClearHeaders（）;

                     Response.ClearContent（）;

                     Response.Clear（）;&
                     Response.Charset的= QUOT;中文英寸;

                &NBSP ;   Response.ContentEncoding = System.Text.Encoding.Default;

                     Response.AddHeader（QUOT;内容处置"，"附件;文件名= excel.xls"）;

Response.ClearHeaders();
                    Response.ClearContent();
                    Response.Clear();
                    Response.Charset = "big5";
                    Response.ContentEncoding = System.Text.Encoding.Default;
                    Response.AddHeader("content-disposition", "attachment; filename=excel.xls");

                     //Response.AddHeader("content-length" ;, file.Length.ToString（））;

                     Response.ContentType =" application / ms-excel";

                    //Response.AddHeader("content-length", file.Length.ToString());
                    Response.ContentType = "application/ms-excel";

                    字节[] myExcel = System.IO.File.ReadAllBytes（QUOT; excel.xls"）;

          &NBSP ;         Response.OutputStream.Write（myExcel，0，myExcel.Length）;

             &NBSP ;      Response.Flush（）;

                    byte[] myExcel = System.IO.File.ReadAllBytes("excel.xls");
                    Response.OutputStream.Write(myExcel, 0, myExcel.Length);
                    Response.Flush();

当第一次点击按钮时，有响应并有excel下载提示，但是当我再次点击按钮时没有响应。

When the button is first click, there is response and have excel download prompt, but there is no response when I click the button again.

为什么第二次单击ASP.NET按钮时没有响应？对它的任何解决方案？
