我不能让它适用于vb

问题描述

我尝试使用vb.net进行面部检测。

我这样做： 

 Const APIKEY As String =" my api密钥QUOT; 
 
 Dim faceservice As New FaceServiceClient（APIKEY）

[...]

然后我得到了我的文件路径进入'filelist'var。

然后我调用：

私有异步函数run（）As Task 
 
 For i = 1 to filelist.Count  -  1 
 
使用imageFileStream As System.IO.FileStream = IO.File.OpenRead（filelist（i  -  1））
 
 Dim faces1 = Await faceservice.DetectAsync（imageFileStream）
 Dim faceid1 = faces1（0）.FaceId 
 
结束使用
 
使用imageFileStream2 As System.IO.FileStream = IO.File.OpenRead（filelist（i））
 
 Dim faces2 = Await faceservice.DetectAsync（imageFileStream2）
 Dim faceid2 = faces2（0）.FaceId 
 
结束使用
 
 
下一个
 
 
结束功能

但是调用不返回任何面（faces1和face2什么都不是）并且没有错误发生。

任何人都可以帮助我吗？ ：）

（抱歉，英语不是我的母语）

编辑：我添加了对ClientLibrary的引用，而不是我在c＃sdk中找到的，我添加了这个： 

 Imports Microsoft.ProjectOxford .Face 
 
 Imports Microsoft.ProjectOxford.Face.Contract 

解决方案

Hi,

I try to make face detection works with vb.net.

I make it like this : 

Const APIKEY As String = "my api key"

Dim faceservice As New FaceServiceClient(APIKEY)

[...]

Then i get my file paths into 'filelist' var.

then i call :

 Private Async Function run() As Task

        For i = 1 To filelist.Count - 1

            Using imageFileStream As System.IO.FileStream = IO.File.OpenRead(filelist(i - 1))

                Dim faces1 = Await faceservice.DetectAsync(imageFileStream)
                Dim faceid1 = faces1(0).FaceId

            End Using

            Using imageFileStream2 As System.IO.FileStream = IO.File.OpenRead(filelist(i))

                Dim faces2 = Await faceservice.DetectAsync(imageFileStream2)
                Dim faceid2 = faces2(0).FaceId

            End Using


        Next


    End Function

But the call doesn't return any faces (faces1 and face2 are nothing) and no errors occurs.

Can anyone please help me ? :)

(sorry, english is not my mother language)

edit : i added a reference to ClientLibrary than i found into c# sdk and i added this : 

Imports Microsoft.ProjectOxford.Face

Imports Microsoft.ProjectOxford.Face.Contract
