Process.Start()抛出"Access Denied"(拒绝访问)消息.错误 [英] Process.Start() throws an "Access Denied" error

问题描述

当我执行一个过程并尝试重定向输出/错误时，出现以下错误:

When I execute a process through and try to redirect the output/error, I get the following error:

System.ComponentModel.Win32Exception (0x80004005): Access is denied 
at System.Diagnostics.Process.CreatePipe(SafeFileHandle& parentHandle, SafeFileHandle& childHandle, Boolean parentInputs) 
at System.Diagnostics.Process.StartWithCreateProcess(ProcessStartInfo startInfo) 
...

可能是什么问题?这是一个复制品:

What could be wrong? Here is a repro:

string path = "C:\\batch.cmd";
using (Process proc = new Process())
{
    bool pathExists = File.Exists(path);
    if(!pathExists) throw new ArgumentException("Path doesnt exist");

    proc.StartInfo.FileName = path;
    proc.StartInfo.WorkingDirectory = workingDir.FullName;
    proc.StartInfo.UseShellExecute = false;
    proc.StartInfo.RedirectStandardError = true;
    proc.StartInfo.RedirectStandardOutput = true;       

    proc.Start(); //Exception thrown here
    proc.WaitForExit();
}

推荐答案

没有合适的理由使此操作失败，代码尚未达到可以对安全性进行任何操作的地步.这是环境，机器上的某些东西正在干扰.首先重新启动，然后禁用反恶意软件.如果仍然不能解决问题，请使用TaskMgr.exe，进程"选项卡并任意启动杀死进程，如果运气好的话，您会遇到麻烦的.在superuser.com上询问有关使计算机稳定的问题

No decent reason for this to fail, the code has not yet gotten to a point where it would do anything security-sensitive. This is environmental, something on your machine is interfering. Reboot first, disable anti-malware next. If that doesn't help then use TaskMgr.exe, Processes tab and arbitrarily start killing processes, with some luck you'll hit the evil-doer.
