.这个就是处理 【托管程序】的入口方法了

 [SecurityPermission(SecurityAction.LinkDemand, Unrestricted=true)]
 public int ProcessRequest(IntPtr ecb, int iWRType){
     IntPtr zero = IntPtr.Zero;
     if ( iWRType ==  ){zero = ecb;ecb = UnsafeNativeMethods.GetEcb(zero);}
     ISAPIWorkerRequest wr = null; //ISAPIWorkerRequest : HttpWorkerRequest
     try{
         bool useOOP = iWRType == ;
         wr = ISAPIWorkerRequest.CreateWorkerRequest(ecb, useOOP);//将 ecb 句柄封装成 HttpWorkerRequest 的 源码在此 ！！！
         wr.Initialize();
         string appPathTranslated = wr.GetAppPathTranslated();
         string appDomainAppPathInternal = HttpRuntime.AppDomainAppPathInternal;

         if ((appDomainAppPathInternal == null) || StringUtil.EqualsIgnoreCase(appPathTranslated, appDomainAppPathInternal))
         {
             HttpRuntime.ProcessRequestNoDemand(wr);
             return ;
         }

         object[] args = new object[] { appDomainAppPathInternal, appPathTranslated };
         HttpRuntime.ShutdownAppDomain(ApplicationShutdownReason.PhysicalApplicationPathChanged, SR.GetString("Hosting_Phys_Path_Changed", args));
         return ;
     }catch (Exception exception){
         try{ WebBaseEvent.RaiseRuntimeError(exception, this); }catch{}
         if ( (wr == null) || !(wr.Ecb == IntPtr.Zero) ){throw;}
         if ( zero != IntPtr.Zero ){UnsafeNativeMethods.SetDoneWithSessionCalled(zero);}
         if ( exception is ThreadAbortException ){Thread.ResetAbort();}
         return ;
     }
 }
