1. Demand Analysis

Users need a simple, easy-to-use software, with this view, the MP3 software is as follows:

2. Design Ideas

For the MP3 software, my bedroom thinks that adding a control is enough, but it should need a user interface, so we added the operation to read the MP3 file, and we can switch it arbitrarily. The 3 button is added and the bool is initially set to true, with his true or false to determine the space switch.

3, the code is as follows

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.io;using System.Media;namespace music Playback {        Public partial class Form1:form {public Form1 () {InitializeComponent ();        } bool Zaq = true;            private void Button1_Click (object sender, EventArgs e) {OpenFileDialog open = new OpenFileDialog (); Open.            Filter = "MP3 file |*.mp3| all formats |*.*";            DialogResult ds = Openfiledialog1.showdialog ();            String sa;                               if (ds = = DialogResult.OK) {string qwe= sa = openfiledialog1.filename; int index3 = sa.                LastIndexOf ("\ \"); string s = sa.                Substring (index3+1);                         LISTBOX1.ITEMS.ADD (s); } else {MessageBox.Show ("You have not selected any files, please re-Choose!            "," warning message ", Messageboxbuttons.okcancel, messageboxicon.warning);            }} private void Listbox1_doubleclick (object sender, EventArgs e) {                        String se =listbox1.getitemtext (listbox1.selecteditem);     Axwindowsmediaplayer1.url = SE;                        } private void Listbox1_Click (object sender, EventArgs e) {ListBox lis = new ListBox (); String se = lis. GetItemText (LIS.            SelectedItem);                                                              Axwindowsmediaplayer1.url = "se"; private void Button2_Click (object sender, EventArgs e) {if (Zaq = = Tru                e) {axWindowsMediaPlayer1.Ctlcontrols.pause ();            Zaq = false;                } else {axWindowsMediaPlayer1.Ctlcontrols.play ();             Zaq = true;  }                             }      private void Button3_Click (object sender, EventArgs e) {axwindowsmediaplayer1.url = Openfiledialo G1.                                       FileName; }                                          }}

6. Summary　　

O (︶^︶) o Alas, incremental development did a few, at first no clue, just made this, (single/multi-loop, loading lyrics, pictures did not do) in the following we will add.

For the addition of several teammates, you can make a lot of suggestions, the idea is open, but each of us should at least achieve a part of the code, so the team's scheduling and its own ability to be strengthened.
