C# 程序启动其他进程程序

1  启动一个独立进程，需要用到的命名空间是：using System.Diagnostics;   进程类是 Process ，进程的相关参数信息类是 ProcessStartInfo

2  等待启动的控制台app代码：

using System;
using System.Threading;
namespace ShowConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("app start!");
            foreach (string item in args)
            {
                Console.WriteLine(" accept a arg that is {0}", item);

Thread.Sleep(3000);             
            }

Console.WriteLine("app stop!");
        }
    }
}

3  启动模式:  并行和串行模式，注意比较代码区别。

using System;
using System.Threading;
using System.Diagnostics;

namespace HDTest
{
    class Program
    {
        static void Main(string[] args)
        {

for (int i = 0; i < 2; i++)
           {
               //并行： 多个同命实例进程一起执行
               RunMutilInstanceProcess(i);

//串行，一个进程启动结束后，运行下一个
             //  WaitSonProcess(i);

Thread.Sleep(2000);

}

Console.ReadLine();
        }

static void RunMutilInstanceProcess(int i)
        {
            string appPath = @"E:\VS2010Code\AppTest\ShowConsoleApp\bin\Debug\ShowConsoleApp.exe";
            ProcessStartInfo process = new ProcessStartInfo();
            process.FileName = appPath;
            process.Arguments = "process " + i.ToString();

process.UseShellExecute = false;
            process.CreateNoWindow = true;

process.RedirectStandardOutput = true;
            Process.Start(process);

// string Result = p.StandardOutput.ReadToEnd();
           // Console.WriteLine("the console app output is {0}", Result);
             Console.WriteLine(" process {0} start", i);
        }

static void WaitSonProcess(int i)
        {
            Process process = new Process();
            string appPath = @"E:\VS2010Code\AppTest\ShowConsoleApp\bin\Debug\ShowConsoleApp.exe";
            process.StartInfo.FileName = appPath;
            process.StartInfo.Arguments = "process " + i.ToString();

process.StartInfo.UseShellExecute = false;
            process.StartInfo.CreateNoWindow = true;

process.StartInfo.RedirectStandardOutput = true;

// process.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
            // Start the process
            process.Start();

Console.WriteLine(" process {0} start", i);
            // Wait that the process exits
             process.WaitForExit();

Console.WriteLine("the process  had exits");

// Now read the output of the DOS application
            string Result = process.StandardOutput.ReadToEnd();

Console.WriteLine("the console app output is {0}", Result);
        }
    }
}
