Question

我将QuickCross用作我的项目的MVVM框架：https://github.com/MacawNL/QuickCross 作为指南，我创建了一个命令

public RelayCommand RegisterCommand /* Data-bindable command that calls Register(), generated with cmd snippet. Keep on one line - see http://goo.gl/Yg6QMd for why. */ { get { if (_RegisterCommand == null) _RegisterCommand = new RelayCommand(Register); return _RegisterCommand; } } private RelayCommand _RegisterCommand; public const string COMMANDNAME_RegisterCommand = "RegisterCommand";

    private void Register()
    {
        //TODO: Check valid model

        var request = new RegistrationRequest
        {
            FullName = FullName,
            UserEmail = Email,
            Password = Password,
            UserType = UserType
        };
        var response =  userClientApi.Register(request);

        if (response.Succeed)
        {
            //TODO: handle success data
        }
    }

我工作得很好，但我创建了一个ASYNC函数：RegisterAsync。如何在RelayCommand中调用async方法如下：

var response = await userClientApi.RegisterAsync(request);

感谢您的阅读。

Answer 1

private async void Register()

注意，虽然RelayCommand不会等待调用Register方法，但在Register方法中，执行将是串行的。
