SilverLight读取XML文件

概述首先第一步用ScriptOjbect对象确定要读取的文件的位置,代码如下: Public Shared Function GetUrl() As String         Dim location As ScriptObject = TryCast(HtmlPage.Window.GetProperty("location"), ScriptObject)         Dim r As O

首先第一步用ScriptOjbect对象确定要读取的文件的位置,代码如下:

Public Shared Function GetUrl() As String
        Dim location As ScriptObject = TryCast(HTMLPage.Window.GetProperty("location"),ScriptObject)
        Dim r As Object = location.GetProperty("href")
        Dim url As String = r.ToString().Substring(0,r.ToString().LastIndexOf("/"))
        Return url
End Function

其次用WebClIEnt对象以及uri对象下载xml文件,sans-serif;">Private Sub Init()
        Dim uri As Uri = New Uri(GetUrl() + "/config.xml",UriKind.absolute)
        Dim clIEnt As WebClIEnt = New WebClIEnt()
        AddHandler clIEnt.OpenReadCompleted,AddressOf OpenReadCompleted
        clIEnt.OpenReadAsync(uri)
End Sub

最后用XMLReader对象对下载的XML文件进行加工处理,sans-serif;">Private Sub OpenReadCompleted(ByVal sender As Object,ByVal e As OpenReadCompletedEventArgs)
        Dim stream As Stream = e.Result
        Using reader As XmlReader = XmlReader.Create(stream)
            reader.ReadToFollowing("TestData")
            Dim testData As String = reader.ReadElementContentAsstring()
            reader.ReadToNextSibling("TestData2")
            Dim testData2 As String = reader.ReadElementContentAsstring()
        End Using
End Sub

也许在Asp.net中微软的WebConfigurationManager对象以及ConfigurationManager对象也是这样工作的吧！哈哈,只是猜测!
