}

In the first place in a column to the ListView assignment, the key information in the Tag, such as a data ID, click click or double-click the tests for one, may be ordered multinomial, direct to choose the first item is ok, then take the Tag, to Tag can do whatever you want in the future

Demo: 
ListView lv=new ListView (); 
/* 
Lv. Click +=(object sender, EventArgs e)=& gt; 
{

}; 
*/
Lv. SelectedIndexChanged +=(object sender, EventArgs e)=& gt; 
{
ListView list=sender as ListView. 
If (list. SelectedItems. Count & gt; 0)
