https://stackoverflow.com/questions/19087920/calling-async-method-from-another-class

private async void {await} 不需要await來接
private async task {await}

private async void 不需要await來接

async裡面就可以放await

await 可以進入但會報錯
Task.Run 沒辦法進入想進入的function

private async void {} -> private async task {await} -> private async void {await}
