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 };
            }
        }
    }
}
