c# - PsExec 在从编译为 "windows application"的非常简单的 c# 或 c++ gui 程序执行时挂起

Question

我在从编译为“windows 应用程序”(而不是“控制台应用程序”)的非常简单的 c# 或 c++ gui 程序执行时遇到 PsExec 挂起。在下面在下面的 C) 部分我粘贴了重现问题的代码，在 D) 部分我粘贴了重现相同问题的 C++ 代码。

当 psexec 挂起时，本地附加到 psexec 后的 windbg 输出粘贴在 B 部分下)。

我的程序在转储粘贴在 A 部分下的输出后挂起)。

如果您将 psexec 命令替换为任何本地命令，则该程序可以正常工作，例如ProcessStartInfo("cmd.exe", "/c dir c:\windows\*.*");

我想知道是否有人经历过并找到了解决方案。将不胜感激。

谢谢，沙拉吉什

PSExec 对我来说太随意了。我没有努力按照您的方式重新创建问题，但我通过使用“PAExec”避免了麻烦，这是一个看似有值(value)的精神继承者: http://www.poweradmin.com/PAExec/
