.net framework里有了许多COM组件,我们可以根据应用程序的需要来使用这些组件,不用自己再去 “造轮子”了。
第一个示例是来制作一个VCD播放器.这里我使用了Windows自带的Media Play来播放多媒体文件。
选择‘工具箱’—‘组件’,右击,选择‘添加/移除项’—‘COM组件‘(如果你是第一次使用Windows Media Play控件,在列表中是没有这个控件的,可以在系统文件夹下找到,一般是在C:\Windows/System32/msdxm.ocx,把这个控件加入到控件列表中,就可以使用了。
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
public class Form1 : System.Windows.Forms.Form
private AxMediaPlayer.AxMediaPlayer axMediaPlayer1;
private void btnPlay_Click(object sender, System.EventArgs e)
if(this.axMediaPlayer1.FileName.Trim()=="")
MessageBox.Show(this," 请选择要播放的文件!!!!","信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
this.axMediaPlayer1.Play();
private void btnPause_Click(object sender, System.EventArgs e)
if(this.axMediaPlayer1.FileName.Trim()=="")
MessageBox.Show(this," 请选择要播放的文件!!!"," 信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
this.axMediaPlayer1.Pause();
private void btnStop_Click(object sender, System.EventArgs e)
if(this.axMediaPlayer1.FileName.Trim()=="")
MessageBox.Show(this,"请选择要播放的文件","信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
this.axMediaPlayer1.Stop();
private void menuItem3_Click(object sender, System.EventArgs e)
private void menuItem2_Click(object sender, System.EventArgs e)
this.openFileDialog1.ShowDialog();
string strFileName = this.openFileDialog1.FileName;
if(strFileName.Trim()=="")
this.axMediaPlayer1.FileName = strFileName;
private void menuItem4_Click(object sender, System.EventArgs e)
this.axMediaPlayer1.AboutBox();
private void menuItem5_Click(object sender, System.EventArgs e)
this.axMediaPlayer1.FastForward();
选择‘工具箱’—‘组件’,右击,选择‘添加/移除项’—‘COM组件‘把“MSWebDVD
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
public class Form1 : System.Windows.Forms.Form
private AxMSWEBDVDLib.AxMSWebDVD axMSWebDVD1;
private void btnPlay_Click(object sender, System.EventArgs e)
catch(System.Exception ex)
MessageBox.Show(ex.Message.ToString());
private void btnPause_Click(object sender, System.EventArgs e)
this.axMSWebDVD1.Pause();
catch(System.Exception ex)
MessageBox.Show(ex.Message.ToString());
private void btnStop_Click(object sender, System.EventArgs e)
catch(System.Exception ex)
MessageBox.Show(ex.Message.ToString());
private void btnOut_Click(object sender, System.EventArgs e)
this.axMSWebDVD1.Eject();
catch(System.Exception ex)
MessageBox.Show(ex.Message.ToString());
第三个示例是制作一个Flash播放器。选择‘工具箱’—‘组件’,右击,选择‘添加/移除项’—‘COM组件‘把“Shockwave Flash Object”这个控件加入到控件列表中,就可以使用了。
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
public class Form1 : System.Windows.Forms.Form
private AxShockwaveFlashObjects.AxShockwaveFlash axShockwaveFlash1;
private void menuItem2_Click(object sender, System.EventArgs e)
if(this.openFileDialog1.ShowDialog()==DialogResult.OK)
this.axShockwaveFlash1.Movie = this.openFileDialog1.FileName;
this.Text = "播放的是-"+this.openFileDialog1.FileName;
private void btnPlay_Click(object sender, System.EventArgs e)
if(this.openFileDialog1.FileName.Length>0)
this.axShockwaveFlash1.Play();
MessageBox.Show(this,"请选择文件!!!","信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
private void btnStop_Click(object sender, System.EventArgs e)
if(this.openFileDialog1.FileName.Length>0)
this.axShockwaveFlash1.Stop();
MessageBox.Show(this,"请选择文件!!!","信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
private void btnFisrt_Click(object sender, System.EventArgs e)
if(this.openFileDialog1.FileName.Length>0)
this.axShockwaveFlash1.Rewind();
MessageBox.Show(this,"请选择文件!!!","信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
private void btnLast_Click(object sender, System.EventArgs e)
if(this.openFileDialog1.FileName.Length>0)
this.axShockwaveFlash1.Back();
MessageBox.Show(this,"请选择文件!!!","信息提示“,MessageBoxButtons.OK,MessageBoxIcon.Information);
private void btnNext_Click(object sender, System.EventArgs e)
if(this.openFileDialog1.FileName.Length>0)
this.axShockwaveFlash1.Forward();
MessageBox.Show(this,"请选择文件!!!","信息提示”,MessageBoxButtons.OK,MessageBoxIcon.Information);
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.Collections;
using System.ComponentModel;
using System.Windows.Forms;
public class Form1 : System.Windows.Forms.Form
private AxRealAudioObjects.AxRealAudio axRealAudio1;
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)
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。
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
public class Form1 : System.Windows.Forms.Form
private AxMediaPlayer.AxMediaPlayer axMediaPlayer1;
private void menuItem3_Click(object sender, System.EventArgs e)
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;
private void btnPlay_Click(object sender, System.EventArgs e)
if(this.listView1.Items.Count>0)
if(this.listView1.SelectedItems.Count>0)
int pos = this.listView1.SelectedItems[0].Index;
string fName = this.listView1.Items[pos].SubItems[3].Text;
this.axMediaPlayer1.FileName = fName;
this.axMediaPlayer1.Play();
MessageBox.Show(this,"ÇëÑ¡ÔñÒª²¥•ÅµÄ¸èÇú!!!","ÐÅÏ¢Ìáʾ",MessageBoxButtons.OK,MessageBoxIcon.Information);
private void btnPause_Click(object sender, System.EventArgs e)
if(this.axMediaPlayer1.FileName.Length>0)
this.axMediaPlayer1.Pause();
MessageBox.Show(this,"请选择要播放的歌曲!!!","信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
private void btnStop_Click(object sender, System.EventArgs e)
if(this.axMediaPlayer1.FileName.Length>0)
this.axMediaPlayer1.Stop();
MessageBox.Show(this," 请选择要播放的歌曲!!!"," 信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
private void btnLast_Click(object sender, System.EventArgs e)
if(this.listView1.Items.Count>0)
if(this.listView1.SelectedItems.Count>0)
int pos = this.listView1.SelectedItems[0].Index;
this.listView1.Items[pos-1].Selected = true;
string fName = this.listView1.Items[pos-1].SubItems[3].Text;
this.axMediaPlayer1.FileName = fName;
this.axMediaPlayer1.Play();
MessageBox.Show(this,"已经是第一首歌曲了!!!"," 信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
MessageBox.Show(this," 请选择要播放的歌曲!!!"," 信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
private void btnNext_Click(object sender, System.EventArgs e)
if(this.listView1.Items.Count>0)
if(this.listView1.SelectedItems.Count>0)
int pos = this.listView1.SelectedItems[0].Index;
if(pos<this.listView1.Items.Count-1)
this.listView1.Items[pos+1].Selected = true;
string fName = this.listView1.Items[pos+1].SubItems[3].Text;
this.axMediaPlayer1.FileName = fName;
this.axMediaPlayer1.Play();
MessageBox.Show(this,"已经是最后一首歌曲了!!!","信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
MessageBox.Show(this," 请选择要播放的歌曲!!!","信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
