下载文件后关闭窗体问题
求大侠帮忙看下,,如何才能在下载文件完后让窗体关闭.
下面是我的代码.放在a.aspx的Page_Load里面,,可是保存完文件还是不会关闭.
求教应该如何改呀?
我看过网上那篇下载文件关闭的文章 ,但用在这里还是不起用,,
在线等待,,测试通过马上结贴,,谢谢
string AppPath = HttpContext.Current.Request.PhysicalApplicationPath;
string ImageFolderPath = AppPath + "Public\\127933387836406250ball6.gif ";
FileStream myFile = new FileStream(ImageFolderPath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
BinaryReader br = new BinaryReader(myFile);
context.Response.Buffer = false;
context.Response.Clear();
context.Response.AddHeader( "Connection ", "Keep-Alive ");
context.Response.ContentType = "application/octet-stream ";
context.Response.AddHeader( "Content-Disposition ", "attachment;filename= " + HttpUtility.UrlEncode( "无聊提.jpg "));
context.Response.AddHeader( "Content-Length ", myFile.Length.ToString());
while (true)
{
//开辟缓冲区空间
byte[] buffer = new byte[1024];
//读取文件的数据
int leng = myFile.Read(buffer, 0, 1024);
if (leng == 0)//到文件尾，结束
break;
if (leng == 1024)//读出的文件数据长度等于缓冲区长度，直接将缓冲区数据写入HttpUtility.UrlEncoding(filename.ToString ())
context.Response.BinaryWrite(buffer);
else
{
//读出文件数据比缓冲区小，重新定义缓冲区大小，只用于读取文件的最后一个数据块Server.UrlEncode(fileName)
byte[] b = new byte[leng];
for (int i = 0; i < leng; i++)
b[i] = buffer[i];
context.Response.BinaryWrite(b);
}
}
myFile.Close();//关闭下载文件
context.Response.Flush();
context.Response.End();
[解决办法]
窗体关闭:Response.Write( " <script> window.close(); </script> ");

和浏览器的补订包有关，我在项目中也经历过这种情况，同样的代码在相同版本的不同补订包浏览器中执行的结果是不同的。
[解决办法]
把context.Response.Flush();
context.Response.End();这两句去掉再加上Response.Write( " <script> window.close(); </script> ");
