3种方式遍历Repeater中的CheckBox并全选

方式1:

foreach (Control c in this.Repeater1.Controls)
{
    HtmlInputCheckBox check = (HtmlInputCheckBox)c.FindControl("chkSelect");
    if( check != null )
    {
        check.Checked = true;
    }
}

方式2:

for (int i=0;i<this.Repeater1.Items.Count;i++)
{
    HtmlInputCheckBox check = (HtmlInputCheckBox)this.Repeater1.Items[i].FindControl("chkSelect");
    if( check != null )
    {
        check.Checked = true;
    }
}

方式3:
foreach( RepeaterItem item in this.Repeater1.Items )
{
    HtmlInputCheckBox check = (HtmlInputCheckBox)item.FindControl("chkSelect");
    if( check != null )
    {
        check.Checked = true;
    }
}
