楼主：摆脱小农意识，C#学完出学堂, 交上毕业“论文”

Program.cs文件，主要是建立互斥，阻止多实例运行(方法还有许多)
using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;
using System.Threading;//Mutex类需要

namespace WindowsFormsApplication2
{
    static class Program
    {
        /// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        [STAThread]
        static void Main()
        {
            bool createdNew;
            Mutex mutexFile = new Mutex(false, "WindowsFormsApplication2", out createdNew);//创建互斥
            if (createdNew)
            {//成功创建无进程运行
                Application.EnableVisualStyles();
                Application.SetCompatibleTextRenderingDefault(false);
                Application.Run(new Form1());
            }
            else
            {//创建失败有进程在运行
                MessageBox.Show("对不起,有一进程在工作", "系统提示", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
            }
        }
    }
}

Form1.cs文件，程序的主体，主要是VS如何调用DLL，关闭窗口提示，异常的捕捉等.
