第四个示例是制作一个RealPlay播放器。选择‘工具箱’—‘组件’，右击，选择‘添加/移除项’—‘COM组件‘,把“RealPlayer G2 Control”这个控件加入到控件列表中，就可以使用了。
为了简单起见，就直接使用它的控制面板了，代码如下：
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
namespace RealPlayDemo
{
public class Form1 : System.Windows.Forms.Form
{
private AxRealAudioObjects.AxRealAudio axRealAudio1;
#region
private void InitializeComponent()
{
this.axRealAudio1 = new AxRealAudioObjects.AxRealAudio();
}
#endregion
private void menuItem2_Click(object sender, System.EventArgs e)
{
if(this.openFileDialog1.ShowDialog()==DialogResult.OK)
{
this.axRealAudio1.Source = this.openFileDialog1.FileName;
this.axRealAudio1.DoPlay();
}
}
private void menuItem3_Click(object sender, System.EventArgs e)
{
Application.Exit();
}
}
}
最后一个示例是对第一个Windows Media Play播放器的扩展，用它来制作一个Mp3播放器。选择‘工具箱’—‘组件’，右击，选择‘添加/移除项’—‘COM组件‘,把“Windows Media Play”这个控件加入到控件列表中，就可以使用了。
代码如下：
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using System.IO;
namespace MP3PlayerDemo
{
public class Form1 : System.Windows.Forms.Form
{
private AxMediaPlayer.AxMediaPlayer axMediaPlayer1;
#region
private void InitializeComponent()
{
this.axMediaPlayer1 = new AxMediaPlayer.AxMediaPlayer();
}
#endregion
private void menuItem3_Click(object sender, System.EventArgs e)
{
Application.Exit();
}
private void menuItem2_Click(object sender, System.EventArgs e)
{
if(this.openFileDialog1.ShowDialog()==DialogResult.OK)
{
this.listView1.Items.Clear();
string[] FileNames = this.openFileDialog1.FileNames;
foreach(string fName in FileNames)
{
System.IO.FileInfo fInfo = new FileInfo(fName);
float fSize = (float)fInfo.Length/(1024*1024);
this.axMediaPlayer1.FileName = fName;
this.axMediaPlayer1.Stop();
string author = this.axMediaPlayer1.GetMediaInfoString(MediaPlayer.MPMediaInfoType.mpClipAuthor);
string shortFileName = fName.Substring(fName.LastIndexOf("\\")+1);
shortFileName = shortFileName.Substring(0,shortFileName.Length-4);
string[] subItem = {shortFileName,author,fSize.ToString().Substring(0,4)+"M",fName};
ListViewItem item = new ListViewItem(subItem);
this.listView1.Items.Add(item);
this.listView1.Items[0].Selected = true;
}
}
}
