C# Azure移动服务-Facebook注销

我使用Azure移动服务Facebook身份验证创建了.NET应用程序。我使用了凭证：

// Login with the identity provider.
        user = await App.MobileService
            .LoginAsync(provider);

        // Create and store the user credentials.
        credential = new PasswordCredential(provider,
            user.UserId, user.MobileServiceAuthenticationToken);
        vault.Add(credential);

如何注销？

MobileServiceClient.Logout

文档：

使用

此方法在调用MobileServiceClient.Logout方法以将用户注销Azure移动服务实例之前，清除身份提供商设置的所有cookie

以下代码示例显示iOS平台的注销方法：

public void Logout()
{
  foreach (var cookie in NSHttpCookieStorage.SharedStorage.Cookies) {
    NSHttpCookieStorage.SharedStorage.DeleteCookie (cookie);
  }

  App.Client.Logout ();
}   

public void Logout ()
{
  CookieManager.Instance.RemoveAllCookie ();
  App.Client.Logout ();
}

public void Logout()
{
  ...
  AzureTodo.App.Client.Logout();
}

Android平台的代码：

public void Logout()
{
  foreach (var cookie in NSHttpCookieStorage.SharedStorage.Cookies) {
    NSHttpCookieStorage.SharedStorage.DeleteCookie (cookie);
  }

  App.Client.Logout ();
}   

public void Logout ()
{
  CookieManager.Instance.RemoveAllCookie ();
  App.Client.Logout ();
}

public void Logout()
{
  ...
  AzureTodo.App.Client.Logout();
}

Windows Phone 8.1平台的代码：

public void Logout()
{
  foreach (var cookie in NSHttpCookieStorage.SharedStorage.Cookies) {
    NSHttpCookieStorage.SharedStorage.DeleteCookie (cookie);
  }

  App.Client.Logout ();
}   

public void Logout ()
{
  CookieManager.Instance.RemoveAllCookie ();
  App.Client.Logout ();
}

public void Logout()
{
  ...
  AzureTodo.App.Client.Logout();
}
