执行CMD命令

可以执行多条命令，用“\r\n”分割

using System;

using System.Diagnostics;

namespace Tool

{

    public class CMDHelper

    {

        public static string[] ExeCommand(string commandText)

        {

            // System.Text.Encoding.RegisterProvider (System.Text.CodePagesEncodingProvider.Instance);

            // System.Console.OutputEncoding = System.Text.Encoding.GetEncoding("gb2312");

            using (var p = new Process())

            {

                p.StartInfo.FileName = Environment.GetEnvironmentVariable("ComSpec");

                p.StartInfo.UseShellExecute = false;

                p.StartInfo.RedirectStandardInput = true;

                p.StartInfo.RedirectStandardOutput = true;

                p.StartInfo.RedirectStandardError = true;

                p.StartInfo.CreateNoWindow = true;

                p.Start();

                p.StandardInput.WriteLine(commandText);

                p.StandardInput.WriteLine("exit");

                p.StandardInput.Close();

                var outputTask = p.StandardOutput.ReadToEndAsync();

                strError  = p.StandardError.ReadToEnd();

                strOutput = outputTask.Result;

                p.WaitForExit();

                return new string[] { strOutput, strError };

            }

        }

    }
