本文介绍了当从非常简单的C#或C ++ gui程序执行时，PsExec挂起，该程序被编译为"Windows应用程序".的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

从一个非常简单的C#或C ++ gui程序执行时，我正在经历PsExec挂起，这些程序被编译为"Windows应用程序"(而不是控制台应用程序").在下面在下面的C)节中，我粘贴了代码以重现该问题，在下面的D)部分中，我粘贴了c ++代码以重现该问题.

I am experiencing PsExec hang while being executed from a very simple c# or c++ gui program compiled as "windows application" (not as "console application"). Under section C) below I have pasted the code to reproduce the problem and under section D) I have pasted the c++ code to reproduce the same problem.

当psexec挂起时，在本地附加到psexec之后的windbg输出将粘贴在B节下.

When the psexec hangs, the windbg output after being attached to psexec locally is pasted under section B).

我的程序在转储根据A)节粘贴的输出后挂起.

My program hangs after dumping the output pasted under section A).

如果将psexec命令替换为任何本地内容，例如，该程序将正常运行ProcessStartInfo("cmd.exe"，"/c目录c:\ windows \ *.*");

The program works fine if you replace psexec command with anything local e.g. ProcessStartInfo("cmd.exe", "/c dir c:\windows\*.*");

我想知道是否有人体验过并找到了解决方案.帮助将不胜感激.

I was wondering if anybody experienced it and found the solution for it. Help will be greatly appreciated.

谢谢，Sharrajesh

C)重现问题的c#代码

C) The c# code to reproduce the problem

using System;
using System.Windows.Forms;
using System.Diagnostics;

namespace WindowsFormsApplication1 {
  static class Program {
    static void DataReceiveHandler(object sender, DataReceivedEventArgs e) {
