想實現的功能：
default.aspx如下：
<Script Language="C#" Runat="Server">
public void Page_Load(Object src,EventArgs e)
{
string Login_System = Request.QueryString["Login_System"];
if(Login_System!=null)
{
switch(Login_System)
{
case "1":
//當等於１時，加載一個1.aspx
//加載到workspace裏去
case "2":
//當等於１時，加載一個2.aspx
//同上
........
}
}
}
</Script>
<html>
<head>
</head>
<body>
<iframe width="100%" height="100%" border=0 frameBorder=0 name="workspace" id="workspace"></iframe>
</body>
</html>
<Script Language="C#" Runat="Server">
public string frameSrc = "";
public void Page_Load(Object src,EventArgs e)
{
string Login_System = Request.QueryString["Login_System"];
if(Login_System!=null)
{
switch(Login_System)
{
case "1":
//當等於１時，加載一個1.aspx
//加載到workspace裏去
frameSrc = "1.aspx"
case "2":
//當等於１時，加載一個2.aspx
//同上
frameSrc = "2.aspx"
........
}
}
}
</Script>
<html>
<head>

<iframe width="100%" height="100%" border=0 frameBorder=0 name="workspace" id="workspace" src="<%= frameSrc%>"></iframe>
