 受保护的异步子Page_Load（ByVal sender As Object，ByVal e As System.EventArgs）Handle Me.Load

       使用client = New HttpClient（）

            Dim endpointUri As String，resourceId As String



           使用discoveryRequest =新HttpRequestMessage（列举HTTPMethod [获取]，" HTTPS：//api.office.com/discovery/v1.0/me/services"）

   &NBSP ;            discoveryRequest.Headers.Add（" Authorization"，" Bearer {token：http：//drezaei.onmicrosoft.com}"）



                使用discoveryResponse =等待client.SendAsync（discoveryRequest）

                    暗淡discoverContent =等待discoveryResponse.Content.ReadAsStringAsync（）

               &NBSP ;   暗淡serviceInfo = JObject.Parse（discoverContent）

                &NBSP ;   endpointUri = serviceInfo（QUOT; serviceEndpointUri"）的ToString（）

              &NBSP ;     RESOURCEID = serviceInfo（QUOT; serviceResourceId"）的ToString（）

              &NBSP ;结束使用

           结束使用



           使用请求=新HttpRequestMessage（列举HTTPMethod [获取]，endpointUri&安培; Convert.ToString（QUOT; / ME /文件夹（ '收件箱'）/信息$的OrderBy = DateTimeReceived％20desc"？））

                request.Headers.Add（" Authorization"，（Convert.ToString（" Bearer {token："）& resourceId）+"}"）



               使用响应=等待client.SendAsync（请求）

                    暗淡的含量=等待response.Content.ReadAsStringAsync（）

               &NBSP ;   对于每个项目在JObject.Parse（内容）中（"值"）

                         Console.WriteLine（" Message"" {0}"""""" {1}"""  """""""""&n; DateTimeReceived"））

 Protected Async Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Using client = New HttpClient()
            Dim endpointUri As String, resourceId As String

            Using discoveryRequest = New HttpRequestMessage(HttpMethod.[Get], "https://api.office.com/discovery/v1.0/me/services")

                End Using
            End Using
        End Using
    End Sub

但每次运行时我都会收到以下错误：

But every time when I run this I get the following error:

endpointUri = serviceInfo（" serviceEndpointUri"）。ToString（）    - > NullReference异常由用户代码处理

endpointUri = serviceInfo("serviceEndpointUri").ToString()    -> NullReference exception was handled by user code

我输入的授权或令牌是错误的吗？ 我从Azure管理站点获得了令牌。

am I typing my Authorization or token wrong?  I got the token from Azure manage site.

我是否需要从其他地方获取令牌或终点uri？

Do i need to get the token or end point uri from somewhere else?

感谢您的任何建议。
