asp.net中GridView控件遍历的小例子

int intCount = this.GridView1.Rows.Count; //总行数
for (int i = 0; i < intCount; i++)
{
  Label1.Text = ((HyperLink)GridView1.Rows[i].Cells[0].Controls[0]).Text.ToString().Trim();

}
for (i = 0; i < GridViewID.Rows.Count; i++)
{
   CheckBox chkVote =  (CheckBox)GridView1.Rows[i].FindControl("CheckBox2");
}

foreach   (GridViewRow   row   in   GridView1.Rows)   
{   
    CheckBox   cb   =   (CheckBox)row.FindControl("CheckBox2");   
    if(cb.Checked==true)   
    {   
    }   
}
