设置了也没有用,于是想到手动清理应用程序池,但又迁配置问题于是改成最后的方式!

protected void StartStopRecycleApp(string method)
{
string AppPoolName = this.tbAppName.Text.Trim();
//string method = "Recycle"; try
{
DirectoryEntry appPool = new DirectoryEntry("IIS://localhost/W3SVC/AppPools");
DirectoryEntry findPool = appPool.Children.Find(AppPoolName, "IIsApplicationPool");
findPool.Invoke(method, null);
appPool.CommitChanges();
appPool.Close();
lbMsg.Text = string.Format("应用程序池{0}{1}成功", AppPoolName,method);
}
catch (Exception ex)
{
lbMsg.Text = string.Format("应用程序池{0}{2}失败:{1}", AppPoolName, ex.Message,method);
}
}

tbAppName是一个textbox,用来输入应用程序池的名字,如“DefaultAppPool”。
当method="Recycle"时就是回收,为“Start”时是启动,为“Stop”时是停止。

注意:
1. 必须引入System.DirectoryServices包
2. 运行此程序的应用程序也的用户必须权限比较高,可以单独为此程序提供应用程序程,或者建立一个虚拟目录在配制里模拟高级用户(如administrators或者system),否则应用程序会抛出“拒绝访问”的异常。

var filePath=Server.MapPath("~/_UploadFile/" + paths[]);
if (File.Exists(filePath))
{
try
{
FileInfo info = new FileInfo(filePath);
long fileSize = info.Length;
HttpContext.Current.Response.Clear(); //指定Http Mime格式为压缩包
HttpContext.Current.Response.ContentType = "application/x-zip-compressed"; // Http 协议中有专门的指令来告知浏览器, 本次响应的是一个需要下载的文件. 格式如下:
// Content-Disposition: attachment;filename=filename.txt
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(paths[], System.Text.Encoding.UTF8));
//不指明Content-Length用Flush的话不会显示下载进度
HttpContext.Current.Response.AddHeader("Content-Length", fileSize.ToString());
HttpContext.Current.Response.TransmitFile(filePath, , fileSize);
HttpContext.Current.Response.Flush();
}
catch
{ }
finally
{
HttpContext.Current.Response.Close();
} //byte[] buffer = null; //using (FileStream stream = new FileStream(Server.MapPath("~/_UploadFile/" + paths[0]), FileMode.Open, FileAccess.Read))
//{
// if (stream.Length > 1000000) {
// StartStopRecycleApp("Recycle");
// }
// buffer = new byte[stream.Length];
// stream.Read(buffer, 0, buffer.Length);
// stream.Close();
//}
//if (buffer != null)
//{
// Response.Clear();
// Response.Charset = "gb2312";
// Response.ContentType = "application/octet-stream";
// Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(paths[1], System.Text.Encoding.UTF8));
// Response.AddHeader("Content-Length", file.fileSize.ToString());
// Response.BinaryWrite(buffer);
// Response.Flush();
// Response.End();
//}
