using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.Runtime.InteropServices; namespace WindowsFormsMedia { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { } [DllImport("kernel32.dll", CharSet = CharSet.Auto)] public static extern int GetShortPathName( string lpszLongPath, string shortFile, int cchBuffer ); [DllImport("winmm.dll", EntryPoint = "mciSendString", CharSet = CharSet.Auto)] public static extern int mciSendString( string lpstrCommand, string lpstrReturnString, int uReturnLength, int hwndCallback ); private void button1_Click(object sender, EventArgs e) { string buf = ""; buf = buf.PadLeft(128, ' '); string file = @"F:/音乐/错错错.mp3"; //视频文件 file = "open " + Convert.ToChar(34) + file + Convert.ToChar(34) + " alias media"; mciSendString(file, buf, buf.Length, 0); //初始化音频文件 mciSendString("play media", buf, buf.Length, 0); //播放音频文件 } } }

群里看到的代码，一实验还真好使
