wcf – Silverlight：当放置在xap中时如何设置ServiceReferences.ClientConfig

在Web应用程序的Web.config中,在AppSetTings中添加一个变量并存储基本URL,请注意,我没有存储SVC文件的位置,稍后我将附加.这是因为我有多个SVC,我通常指向.你可以选择不同的做法.

<appSetTings>
    <add key="serviceURI" value="http://localhost:64457/"/>
 </appSetTings>

在我的Web应用程序的Web页面中,添加一个名为InitParms的参数,这样可以添加一个键值对(由逗号分隔,由XAP文件读取)

<div id="silverLightcontrolHost">
    <object data="data:application/x-silverlight," type="application/x-silverlight-2"
        width="100%" height="100%" ID="Xaml1" >
        <param name="InitParams" value="serviceURI=<%= ConfigurationManager.AppSetTings("serviceURI") %>" />

在Silverlight App.xaml.vb中,将所有的InitParms加载到资源或者你想要的地方

Private Sub Application_Startup(ByVal o As Object,ByVal e As StartupEventArgs) Handles Me.Startup
    If e.InitParams Isnot Nothing Then
        For Each k As Generic.KeyValuePair(Of String,String) In e.InitParams
            Me.resources.Add(k.Key,k.value)
        Next
    End If

然后在任何我的XAML文件中,我可以使用配置的URI初始化服务,我有一个这样的方法

Private Sub Initializeservice()
    Dim uri As String = App.Current.resources("serviceURI")
    If uri Is Nothing OrElse uri = String.Empty Then
        'if there is no value added in the web.config,I can fallBACk to default values
        _client = New serviceClient
    Else
        'Notice I hardcoded the LOCATIOn of the SVC files in the client and append there here,you may choose not to do this
        Dim uri_withservice As String = uri & "svc/secure/service.svc"
        _client = New serviceClient("CustomBinding_service",New EndpointAddress(uri_withservicE))
    End If
End Sub
