c# - 将 Cmd 命令传递给 C# 应用程序

Question

我有一个程序接受 Cmd 命令作为命令参数。

基本上你这样调用它:C:\MyProgram.exe del C:\test.txt

上面的命令工作正常。但是，当我尝试执行 xcopy 命令时，它失败了:

C:\MyProgram.exe xcopy C:\test.txt C:\Temp\Test2.txt

程序代码:

class Program
{
    static void Main(string[] args)
    {
        string command = GetCommandLineArugments(args);

        // /c tells cmd that we want it to execute the command that follows and then exit.
        System.Diagnostics.ProcessStartInfo procStartInfo = new System.Diagnostics.ProcessStartInfo("cmd", @"/D /c " + command);

        procStartInfo.RedirectStandardOutput = true;
        procStartInfo.UseShellExecute = false;

        // Do not create the black window.
        procStartInfo.CreateNoWindow = true;
        procStartInfo.WindowStyle = ProcessWindowStyle.Hidden;

        System.Diagnostics.Process process = new System.Diagnostics.Process();
        process.StartInfo = procStartInfo;
        process.Start();
    }

    private static string GetCommandLineArugments(string[] args)
    {
        string retVal = string.Empty;

        foreach (string arg in args)
            retVal += " " + arg;

        return retVal;
    }
}

我认为您的应用程序正在运行，所以我尝试了该命令并得到了从 stdin 输入的提示:

C:\>xcopy C:\temp\test.html C:\temp\test2.html
Does C:\temp\test2.html specify a file name
or directory name on the target
(F = file, D = directory)?

也许它是轰炸，因为您没有绑定(bind)标准输入，而您的应用只是从执行中返回返回代码。
