vb.net - 如何在 VB.net 中添加对谷歌翻译器的引用？“导入 Google.Cloud.Translation.V2”给了我错误

Question

我正在尝试执行下一个代码，但 de "Import" 语句给了我错误。我已经安装了 Google Cloud SDK，但我现在不知道如何在 Visual Studio 2015 中添加缺少的参考。

这是代码：

Imports Google.Cloud.Translation.V2
Function GoogleTranslateV2Text(sourceText As String, sourceLang As String, targetLang As String) As String
    Try
      Dim TClient As TranslationClient = TranslationClient.Create()
      If sourceLang.ToUpper = targetLang.ToUpper Then
        Return (sourceText)
      End If
      Dim response = TClient.TranslateText(sourceText, targetLang, sourceLang)
      Dim result As String = response.TranslatedText
      Return result
    Catch ex As Exception
      Dim msg As String = "#1#: " & ex.Message
      Return msg
    End Try
  End Function
