学习《C#网络应用编程》的一个开始，在博客上记录下源码以便日后翻用。

引入命名空间：

using System.Diagnostics;

然后直接贴源码啦

namespace ProcessMonitor
{
    public partial class Form1 : Form
    {
        Process[] myProcess;
        public Form1()

            dgv_Process.AutoResizeColumns();
        }

        {
            GetAllProcessToControl();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            GetAllProcessToControl();
        }

        /// 获取全部进程并填充到dgv_Process控件中
