如何从构造函数调用异步方法? [英] How can I call async method from constructor?

问题描述

我需要从我的 Form1 构造函数中调用 async 方法.由于构造函数不能具有返回类型，因此无法添加 async void .我阅读了

I need to call a async method from my Form1 constructor. Since a constructor can't have a return type, I can't add a async void. I read that static constructor can be async but I need to call methods from constructor that aren't static, such as InitializeComponent() (since it's the Form's constructor).

班级是:

public partial class Form1 : Form
{
    InitializeComponent();
    //some stuff
    await myMethod();
}

我也阅读了这但我仍然不知道如何实现(就我而言)，因为该方法仍然需要使用 async .

I read this one too but I still don't know how to implement this (in my case) since the method still requires to use async.

推荐答案

不要在构造函数中执行此操作，而应在窗口的加载事件中执行此操作.您可以将已加载的事件处理程序标记为异步.

Don't do this in the constructor but in the loaded event of the window instead. You can mark the loaded eventhandler as async.
