C#调用mciSendString播放AVI和MP3的类
使用MCI播放类里包含了一些简单的MCI COMMAND命令。
如果要播放RMVB，则另外需要安装插件。
- private void button1_Click(object sender, EventArgs e)

- openFileDialog1.InitialDirectory = @"C:/temp";
- if (openFileDialog1.ShowDialog() == DialogResult.OK)
- {
- string TempFile = openFileDialog1.FileName;
- Temp.AddSoundFile(TempFile);
- Temp.Play();
- }
- }
- }

- this.Invoke((MethodInvoker)delegate { trackBar1.Maximum = sender.PlayMillisecond; trackBar1.Value = PlayPoint; this.Text = PlayPoint.ToString() + "/" + sender.PlayMillisecond.ToString(); });
