英文:
Using two await inside the Blazor (async Task OnInitializedAsync) lifecycle doesn't work properly
问题
我正在使用以下方法进行操作。
protected override async Task OnInitializedAsync()
{
forecasts = await Http.GetJsonAsync<WeatherForecast[]>("sample-data/weather.json");
await someOperation(); // 此操作未执行
}
对此查询有任何建议吗？
英文:
I am using the following method in an operation.
protected override async Task OnInitializedAsync()
{
forecasts = await Http.GetJsonAsync<WeatherForecast[]>("sample-data/weather.json");
await someOperation(); // this action is not perfomred
}
Any suggestion on this query

以下是翻译好的部分：
我以前曾遇到过这个问题，我可以像这样修复它：
protected override async Task OnInitializedAsync()
{
Http.GetJsonAsync<WeatherForecast[]>("sample-data/weather.json").ContinueWith(task => forecasts = task.Result); //创建一个在目标任务完成时异步执行的延续。
await someOperation(); //如果需要，此操作也可以使用ContinueWith来完成。
}

希望这有所帮助。
英文:
I have had this issue in the past and I was able to fix it like:
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
}
