请帮助将列表绑定到datagridvew

问题描述：

我有一个清单<歌曲> ，数据收集器

i have a list<song> ,a datagrivew

Class Song{
public string Name{get;set;}
}
List<Song> songs ;
void Form_Load{

 songs = new List<Song>
{
 new Song() {Name = "song1"},
 new Song() {Name = "song2"},
 new Song() {Name = "song3"}
}

datagridview1.datasource = songs;

}
void button1_click(){

songs.add(new Song() {Name = "song4"})

}

当我单击按钮1时，datagridview1不添加新歌曲.每个人都请帮助我.

我想单击button1数据将自动绑定到datagridview1.

我用过一种方法

when i click to button 1 then datagridview1 not add new songs.everyone help me please.

i want click to button1 data will auto binding to datagridview1.

i have used a way

void button1_click(){ 
songs.add(new Song() {Name = "song4"}) 
datagridview1.datasource = null;

datagridview1.datasource = songs; 
}

但我觉得这不方便.有人请帮我另一种方式.

谢谢.

but i feel it not handy. someone help me another way please.

thanks.
