c# 调用 ShellExecute

using System.Runtime.InteropServices;



namespace ConsoleTest

{

    class Program

    {

        public enum ShowCommands : int

        {

            SW_HIDE = 0,

            SW_SHOWNORMAL = 1,

            SW_NORMAL = 1,

            SW_SHOWMINIMIZED = 2,

            SW_SHOWMAXIMIZED = 3,

            SW_MAXIMIZE = 3,

            SW_SHOWNOACTIVATE = 4,

            SW_SHOW = 5,

            SW_MINIMIZE = 6,

            SW_MAX = 11

        }

        [DllImport("shell32.dll")]

        static extern IntPtr ShellExecute(

            IntPtr hwnd,

            string lpOperation,

            string lpFile,

            string lpParameters,

            string lpDirectory,

            ShowCommands nShowCmd);

        static void Main(string[] args)

        {

            ShellExecute(IntPtr.Zero, "open", @"c:\test.flv", "", "", ShowCommands.SW_SHOWNORMAL);

            System.Console.ReadKey();

        }

    }

}

c#打开文件可以直接用

System.Diagnostics.Process.Start(@"c:\test.flv");
