带参数的CMD命令 [英] CMD command with arguments

问题描述

我正在尝试运行一个看起来像这样的命令(来自C#)
c:\ MyCommand/LOAD> c:\ temp \ mycommand.txt

这是我尝试过的操作，但未创建文件.

流程流程= new Process();
Process.StartInfo.Arguments => c:\\ mycommand.txt";
Process.Start("MyCommand"，"/LOAD");

不会将输出通过管道传输到文件

//还尝试了以下
//Process.Start("MyCommand/LOAD",">c:\temp\mycommand.txt);
//Process.Start("MyCommand，"/LOAD> c:\ temp \ mycommand.txt);

I am trying to run a command (from C# ) that looks like this
c:\MyCommand /LOAD >c:\temp\mycommand.txt

This is what I tried but the file is not created.

Process Process = new Process();
Process.StartInfo.Arguments = " >c:\\mycommand.txt";
Process.Start("MyCommand","/LOAD");

does not pipe the output to a file

//also tried the following
//Process.Start("MyCommand /LOAD",">c:\temp\mycommand.txt");
//Process.Start("MyCommand", " /LOAD >c:\temp\mycommand.txt");

Any help is greatly appreciated

推荐答案

重定向可执行文件输出的另一种方法如下所示:

One another method to redirect the output of an executable is shown below:

using System;
using System.Collections.Generic;
using System.Text;
using System.Diagnostics;
using System.IO;

namespace ConsoleTest
{
    class Program
    {
        static void Main(string[] args)
        {
            ProcessStartInfo start = new ProcessStartInfo();
            start.FileName = @"systeminfo.exe"; // Specify exe name.
            start.UseShellExecute = false;
            start.RedirectStandardOutput = true;
            using (Process process = Process.Start(start))
            {
                StreamWriter sw = new StreamWriter(@"C:\textinfo.txt");

                using (StreamReader reader = process.StandardOutput)
                {
                    string result = reader.ReadToEnd();
                    sw.Write(result);
                    sw.Close();
                }
            }
        }
    }
}

如果不在CMD中启动重定向，则该重定向将不起作用.

因此，您的命令行如下所示:

Redirection doesn''t work if you don''t launch it inside a CMD.

So, your command line would look like this:

CMD.exe /C "<fullpathto>\MyCommand.exe /LOAD > C:\Temp\MyCommand.txt"</fullpathto>

请记住，不允许普通用户在Windows 7中的C:\ Temp中创建文件.请改用TEMP环境变量返回的路径.它将最终出现在用户个人资料的Temp文件夹中.

Keep in mind that normal users are not allowed to create file in C:\Temp in Windows 7. Use the path returned by the TEMP environment variable instead. It will end up in the Temp folder in the users profile.

Process Process = new Process();
Process.StartInfo.Arguments = " >c:\\mycommand.txt";
Process.Start("MyCommand.exe","/LOAD >c:\temp\mycommand.txt");

试试看.

您是否尝试过先在命令提示符下执行命令.如果可以的话，这有效吗?在我们开始诊断代码是否有问题之前.

try that.

Have you tried executing the command in the command prompt first. If so does it work? Before we start to diagnose if something is wrong with the code.
