跨緒問題
在winform測試
增加一個label
在oncompleted
加入一個action
`
private Task DoSomethingUpdateAsync()
{
return Task.Run(async () =>
{
Print("Call DoSomethingUpdateAsync() on background");
await _waiter.WaitAsync();//執行後回到主緒
label1.Text = "updating safe....";
});
}
`
上面代碼沒問題
主要是移除
await _waiter.WaitAsync();//執行後回到主緒
這拋跨緒錯誤
如果oncompleted開放給外部使用
Eg: oncompleted( x=>DoSomethingUpdateAsync())
但外部沒有加入await _waiter.WaitAsync()
我該如何限制呢?
支持winform?
支持winform嗎?
Controls.BeginInvoke();
public IAsyncResult BeginInvoke(Delegate method) => this.BeginInvoke(method, (object[]) null);
