在.Net中使用XML rest服务

我使用MVC和C#以及web API 2创建并托管了一个restful web服务。我现在想做的是使用VB.net中的windows窗体应用程序来使用web服务

有人能告诉我如何使用这个吗？我希望能够得到和投入。

我已经可以用以下代码呼叫该服务，但我的响应是

[｛"BookingID"：1，"BookingReference"："88764GH"，"入住日期"："2014年6月15日"，"退房日期"：

有没有办法知道这是否是XML格式的？如果这是一个愚蠢的问题，我很抱歉。我假设它是XML格式的，如果它是使用WEB API 2控制器调用的，该控制器以XML形式在线显示它。

    ' Creates an HttpWebRequest for the specified URL.  
    Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create("http://mynewwebservice.com/api/booking/1"), HttpWebRequest)
    ' Sends the request and waits for a response for booking with ID 1.
    Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
    ' Calls the method GetResponseStream to return the stream associated with the response. 
    Dim receiveStream As Stream = myHttpWebResponse.GetResponseStream()
    Dim encode As Encoding = System.Text.Encoding.GetEncoding("utf-8")
    ' Pipes the response stream to a higher level stream reader with the required encoding format.  
    Dim readStream As New StreamReader(receiveStream, encode)
    ListBox1.Items.Add(ControlChars.Lf + ControlChars.Cr + "Response stream received")
    Dim read(256) As [Char]
    ' Reads 256 characters at a time.     
    Dim count As Integer = readStream.Read(read, 0, 256)
    ListBox1.Items.Add("HTML..." + ControlChars.Lf + ControlChars.Cr)
    ListBox1.Items.Add("BREAK 1")
    While count > 0
        ' Dumps the 256 characters to a string and displays the string to the console.
        Dim str As New [String](read, 0, count)
        ListBox1.Items.Add(str)
        count = readStream.Read(read, 0, 256)
        ' xmlDocument.LoadXml(String.Format("<root>{0}</root>", readStream.ReadToEnd))
    End While
    ListBox1.Items.Add("")
    ' Releases the resources of the Stream.
    readStream.Close()
    ' Releases the resources of the response.
    myHttpWebResponse.Close()

我基本上有它，但我不能提取所需的节点？我想提取房间号码，更新它，然后将其发送回web服务？

如果在线查看，xml如下：

                          <ArrayofBooking>
                               <Booking>
                                   <BookingID>1</BookingID>
                                   <BookingRef>88764GH</BookingRef>
                                   <CheckinDate>15/06/2014</CheckinDate>
                                   <CheckoutDate>17/06/2014</CheckoutDate>
                                   <Room>122</Room>
                                   <RoomType>Double</RoomType>
                                </Booking>
                            </ArrayofBooking>

任何帮助都将不胜感激！！
