CS代码中，获取Item的值的简单方法：         

        foreach (var item in Request.Form["Item"].Split(new char[] { ',' }))
            {
                Response.Write(item.ToString()+"<bR/>");
            }

方式1:

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

方式2:

for(inti=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 iteminthis.Repeater1.Items )
 {
 HtmlInputCheckBox check=(HtmlInputCheckBox)item.FindControl("chkSelect");
 if( check!=null)
 {
 check.Checked=true;
 }
 }
