asp.net(vb) 怎么声明常量及调用？请举例说明

[qq_25457993]

在模块里声明一个常量，
Public Module Module1

Public Const FL_URL As Integer = "Request.Url.GetLeftPart(UriPartial.Authority)"

End Module
这里怎么调用？
CTL_CURRTYPENAME.InnerHtml="您的位置：<a href='"& R FL_URL &"/case.html' class='a'>案例</a>"

[取名障碍症]

Public Module Module1 Public Const FL_URL As string = "Request.Url.GetLeftPart(UriPartial.Authority)" End Module CTL_CURRTYPENAME.InnerHtml="您的位置：<a href='" & FL_URL & "/case.html' class='a'>案例</a>"
