下面的代码哪有错啊!
<%@ Page Language="C#" ContentType="text/html" ResponseEncoding="gb2312" %>
<script runat="server">
void lbtn_Click(object Sender, EventArgs E) 
{ 
 string arg = Sender.CommandName; 
 if (arg == "First")
  { 
  Response.Write("first");
  } else if (arg == "Prev"){ 
  Response.Write("second");
  } else if (arg == "Next"){ 
  Response.Write("three");
  } else if (arg == "Last"){ 
  Response.Write("four");
  } 
}
</script>

    { 
     string arg = ((LinkButton)Sender).CommandName;
     if (arg == "First")
      { 
      Response.Write("first");
      }
     else if (arg == "Prev"){ 
      Response.Write("second");
      }
     else if (arg == "Next"){ 
      Response.Write("three");
