第五次作业

具体设计：

主要用了Windows Media Player控件，设置不同的属性值来实现它的播放，暂停，快进，快退等功能。

代码实现：

Form1窗体

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;

namespace 播放器
{
    public partial class FrmMPlayer : Form
    {
        public FrmMPlayer()
        {
            InitializeComponent();
        }

        private void FrmMPlayer_Load(object sender, EventArgs e)
        {
            tkbVolumne.Value = 5;
            AxMPlayer.settings.volume = tkbVolumne.Value;
            AxMPlayer.uiMode = "None";
        }
        public string name;
        //打开的单击事件
        private void BtnOpenFile_Click(object sender, EventArgs e)
        {
            string fname;
            OpenFileDialog dlgopen = new OpenFileDialog();
            dlgopen.Filter = "MP3(*.MP3)|*.MP3";
            if (dlgopen.ShowDialog() == DialogResult.OK)
            {
                fname = dlgopen.FileName;
                name = dlgopen.SafeFileName;
                AxMPlayer.URL = fname;
            }
        }
        //"播放"按钮
        private void btnPlay_Click(object sender, EventArgs e)
        {
            AxMPlayer.Ctlcontrols.play();
        }
        //"暂停"按钮
        private void btnPause_Click(object sender, EventArgs e)
        {
            AxMPlayer.Ctlcontrols.pause();
            tmPlayer.Enabled = false; 
        }
        //"停止"按钮
        private void btnStop_Click(object sender, EventArgs e)
        {
            AxMPlayer.Ctlcontrols.stop();
            tmPlayer.Enabled = false;
        }
        //"快进"按钮
        private void btnFastForward_Click(object sender, EventArgs e)
        {
            AxMPlayer.Ctlcontrols.fastForward();
        }
        //"快退"按钮
        private void btnFastReverse_Click(object sender, EventArgs e)
        {
            AxMPlayer.Ctlcontrols.fastReverse();
        }
        //"全屏"按钮
        private void btnFullScreen_Click(object sender, EventArgs e)
        {
            if (AxMPlayer.playState == WMPLib.WMPPlayState.wmppsPlaying)
            {
                AxMPlayer.fullScreen = true;
                AxMPlayer.uiMode = "Full";
            }
        }
        //播放媒体发生变化时触发此事件
        private void AxMPlayer_PlayStateChange(object sender, AxWMPLib._WMPOCXEvents_PlayStateChangeEvent e)
        {
            
            lblTotalTime.Text +=  AxMPlayer.currentMedia.duration;
            tmPlayer.Enabled = true ;
            lblSongName.Text = "歌名：" + name;
        }

        private void tmPlayer_Tick(object sender, EventArgs e)
        {
            lblEscapeTime.Text = "已经播放时间：" + AxMPlayer.Ctlcontrols.currentPosition + "秒";
        }

        private void tkbVolumne_Scroll(object sender, EventArgs e)
        {
            AxMPlayer.settings.volume = tkbVolumne.Value;
        }
        //关闭按钮
        private void btnExit_Click(object sender, EventArgs e)
        {
            Application.Exit();
        }
    }
}

团队编程的总结：

在做这个播放器的时候，我们感觉到我们知识面太窄了，有太多知识我们不知道，在这个程序中就有体现，因为我们没有学过Windows Media Player控件，对它的属性不太了解，所以在程序中“文件名：”“播放总时间”“已播放时间都没有获取到，我们会再试着把它做出来的。

程序的代码是规范的。
