将ASP改为C#，，，第一次，需要一个例子熟悉下
希望高人能将下面的改为C#代码。
----------------------------Session.asp---------------------------------------

<%
AdminUID=session("AdminUID")
AdminPWD=session("AdminPWD")

set rs=server.CreateObject ("ADODB.RecordSet")
rs.Source="select id from Admin where AdminUID='" & AdminUID & "' and  AdminPWD='" & AdminPWD & "'"
rs.Open rs.Source,conn,1,1

if not rs.EOF then
   rs.close
   set rs=nothing
else
   rs.close
   set rs=nothing
   session("AdminUID")=""
   session("AdminPWD")=""
   session("AdminRANK")=""
%>
<script language=javascript>
 alert("登录超时，请重新登录！")
 window.location="index.asp";
</script>
