.BeginSiginin之后的通用COM异常 [英] Generic COM Exception after .BeginSiginin

问题描述

 

大家好，

 

我正在使用通常的通用代码，用户签署Lync，但它间歇性地抛出"通用COM异常"。代码是0x80EF0194"在< _lyncClient.EndSignIn（结果）;下面的行。

I'm using the usual generic code to sign a user in to Lync, but it's intermittently throwing "Generic COM Exception. Code is 0x80EF0194" at the _lyncClient.EndSignIn(result); line below.

// Check if Lync is signed out
                if (_lyncClient.State == ClientState.SignedOut)
                {
                    _lyncClient.BeginSignIn(
                    address,
                    username,
                    password,
                    
                    result =>
                    {
                        if (result.IsCompleted)
                        {
                            _lyncClient.EndSignIn(result);
                        }
                        else
                        {
                            MessageBox.Show(
                            "Nope, that didn't work. Check your credentials.",
                            "Title",
                            MessageBoxButton.OK,
                            MessageBoxImage.Error);
                        }
                    },
                    "Local user signing in" as object);

我改为单独的回调：

   private void SignInCallback(IAsyncResult ar)
        {
            if (ar.IsCompleted == true)
            {
                try
                {
                    _lyncClient.EndSignIn(ar); 
                }
                catch (LyncClientException e)
                {
                    MessageBox.Show("Error= " + e);
                }
            }
        }
