在Blazor (异步任务OnInitializedAsync)生命周期中使用两个等待不能正常工作

Question

我在一个操作中使用了以下方法。

protected override async Task OnInitializedAsync()
{
    forecasts = await Http.GetJsonAsync<WeatherForecast[]>("sample-data/weather.json");
    await someOperation(); // this action is not perfomred
}

关于此查询的任何建议

Answer 1

我以前遇到过这个问题，我能够像这样解决它：

protected override async Task OnInitializedAsync()
{
    Http.GetJsonAsync<WeatherForecast[]>("sample-data/weather.json").ContinueWith(task => forecasts = task.Result); //Creates a continuation that executes asynchronously when the target Task completes.


    await someOperation(); // his action can also be done using ContinueWith if needed
}
