我试图在我的C#WPF应用程序中运行以下代码。每当我使用像dir这样的东西时(我应该提到输出是我在Visual Studio中的工作文件夹的目录,而不是System32),它允许它。但是,如果我使用systeminfo或将工作目录设置为C:\ Windows \ System32,它会挂起......
MessageBox.Show("STARTED");
var processInfo = new ProcessStartInfo("cmd.exe", "/c systeminfo") {
CreateNoWindow = true,
UseShellExecute = false,
RedirectStandardError = true,
RedirectStandardOutput = true,
//WorkingDirectory = @"C:\Windows\System32\"
};
// *** Redirect the output ***
Process process = Process.Start(processInfo);
if (process == null) return false;
process.WaitForExit();
MessageBox.Show("Done");
string output = process.StandardOutput.ReadToEnd().ToLower();
string error = process.StandardError.ReadToEnd();
int exitCode = process.ExitCode;
MessageBox.Show(output);
MessageBox.Show(error);
MessageBox.Show(exitCode.ToString(CultureInfo.InvariantCulture));
有什么想法吗?

试过这个并按预期工作 当然,您需要在进程关闭之前读取重定向的输出。
var processInfo = new ProcessStartInfo("cmd.exe", "/c systeminfo")
{
CreateNoWindow = true,
UseShellExecute = false,
RedirectStandardError = true,
RedirectStandardOutput = true,
WorkingDirectory = @"C:\Windows\System32\"
};
StringBuilder sb = new StringBuilder();
Process p = Process.Start(processInfo);
p.OutputDataReceived += (sender, args) => sb.AppendLine(args.Data);
p.BeginOutputReadLine();
p.WaitForExit();
Console.WriteLine(sb.ToString());
