命令行运行错误

Question

期待在论坛上后，我写了这个片断：

public string ExecuteCmd() 
{ 
    System.Diagnostics.Process process = new System.Diagnostics.Process(); 
    System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo(); 
    startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden; 
    startInfo.FileName = "cmd.exe"; 
    startInfo.Arguments = this.m_command; 
    process.StartInfo = startInfo; 
    process.Start(); 
    string output = process.StandardOutput.ReadToEnd(); 
    process.WaitForExit(); 

    return output; 
} 

的m_command是一个类的成员，在构造函数初始化。 对于我的测试，它是net user。当编译器到达这一点上，我得到以下异常：

StandardOut has not been redirected or the process hasn't started yet. 

哪里是我的错？

Answer 1

你需要这样的：

//.... 
startInfo.Arguments = "/C " + this.m_command; 
process.StartInfo = startInfo; 
process.StartInfo.RedirectStandardOutput = true; 
process.Start(); 
//....
