private void gvButton1_Click(object sender, EventArgs e)
        {
            System.Diagnostics.ProcessStartInfo info = new System.Diagnostics.ProcessStartInfo();
            System.Diagnostics.Process proc = new System.Diagnostics.Process();

            //设置外部程序名(记事本用 notepad.exe 计算器用 calc.exe) 
            info.FileName = "calc.exe";

            //设置外部程序的启动参数 

            info.Arguments = "";

            //设置外部程序工作目录为c:\windows 

            info.WorkingDirectory = "c:/windows/";

            try
            {
                // 
                //启动外部程序 
                // 
                proc = System.Diagnostics.Process.Start(info);
            }
            catch
            {
                MessageBox.Show("系统找不到指定的程序文件", "错误提示！");
                return;
            } 

        }

      proc = System.Diagnostics.Process.Start(启动程序地址);
  

楼上代码中间的那句，方法里面那样写就行了

  public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

            Execute("notepad.exe");



        }

        void Execute(string FileName)

        {

            System.Diagnostics.Process.Start(FileName);

        }

    }
