Xamarin QuickCross如何使用異步命令

Question

我用QuickCross作爲MVVM框架爲我的項目：https://github.com/MacawNL/QuickCross 爲導向，我創建了一個命令

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 
     } 
    } 

我工作的偉大，但我創建了一個異步函數：RegisterAsync。如何在RelayCommand中調用異步方法如下：

var response = await userClientApi.RegisterAsync(request); 

謝謝您的閱讀。

Answer 1

private async void Register() 

請注意，雖然RelayCommand不會等待Register方法的調用，但是在Register方法中執行將是串行的。
