更改参数中常量变量的值

问题描述

好的iam在将变量作为参数传递给需要恒定输入的方法时遇到了一些麻烦.实际上，iam试图实现这一点:

iam遇到麻烦的代码是:

alright iam having some trouble with passing a variable as an argument to a method which requires constant input. Actually iam trying to implement this :

http://msdn.microsoft.com/en-us/library/aa905668.aspx[^]

the code in which iam having trouble is :

 <XmlRpcUrl(xmlrpcurl)> _
Public Interface IWP
        Inherits IXmlRpcProxy

        <xmlrpcmethod("metaweblog.getcategories")> _
         Function getCategories(ByVal args() As String) As category()

        <xmlrpcmethod("metaweblog.newpost")> _
          Function newPost(ByVal blogid As String, ByVal username As String, ByVal password As String, ByVal content As Post, ByVal publish As Boolean) As String

    End Interface

您会看到< xmlrpcurl()>需要一个恒定的值，但我想从用户那里获取输入(可能是一个文本框?).但是显示一个错误，表明需要一个常量变量.

有人有任何解决方法的想法吗?

我也知道接口.但是第一行(< xmlrpcurl()>)是什么意思?

you see <xmlrpcurl()> needs a constant value, but i want to take the input from the user (a textbox maybe ?). But is shows an error saying that a constant variable is required.

does anybody have an idea of any workaround?

Also i know about interfaces. but what is the meaning of the first line (<xmlrpcurl()>) ?
