不要关闭控制台（C＃）

Question

System.Diagnostics.Process.Start("rasdial.exe", "sdsss" "aa" "bb");

该过程将启动新控制台并尝试运行ras，但是当连接失败时它将关闭-如何将控制台保持在屏幕上？

Answer 1

A simple way to achieve that is to simply redirect the standard error. This is a simple example.

namespace AnswerOne
{
    class Program
    {
        static void Main(string[] args)
        {
            //we use a prosessstartinfo 
            System.Diagnostics.ProcessStartInfo procInfo = new System.Diagnostics.ProcessStartInfo("rasdial.exe");
            procInfo.RedirectStandardError = true;
            //must be false
            procInfo.UseShellExecute = false;
            var process = new System.Diagnostics.Process();
            process.StartInfo = procInfo;
            process.Start();
            process.WaitForExit();

            string error = process.StandardError.ReadToEnd();
            //check if there is any error
            if (string.IsNullOrEmpty(error))
            {
                System.Console.WriteLine(error);
            }
            System.Console.WriteLine("Press any key to close");
            System.Console.ReadLine();
        }
    }
}
