在Thread.Sleep中没有冻结替代等待在Task内部

Question

我必须调用一个如下工作的Web API：

1. 上传一首歌
2. 要求对该歌曲进行特定分析
3. 等待该流程已完成
4. 检索并返回结果

我遇到了问题。 3，我尝试了Thread.Sleep，但冻结了用户界面。

如何在不冻结UI的情况下等待任务？

public override async Task Execute(Progress<double> progress, string id)
{
    FileResponse upload = await Queries.FileUpload(id, FileName, progress);
    upload.ThrowIfUnsucessful();

    FileResponse analyze = await Queries.AnalyzeTempo(id, upload);
    analyze.ThrowIfUnsucessful();

    FileResponse status;
    do
    {
        status = await Queries.FileStatus(id, analyze);
        status.ThrowIfUnsucessful();
        Thread.Sleep(TimeSpan.FromSeconds(10));
    } while (status.File.Status != "ready");

    AnalyzeTempoResponse response = await Queries.FileDownload<AnalyzeTempoResponse>(id, status);
    response.ThrowIfUnsucessful();

    Action(response);
}

编辑：这就是我调用任务的方式

async void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
    var fileName = @"d:\DJ SRS-Say You Never Let Me Go.mp3";
    TempoAnalyzeTask task = new TempoAnalyzeTask(fileName, target);
    await task.Execute(new Progress<double>(ProgressHandler), Id);
}
private AnalyzeTempoResponse _response;

private void target(AnalyzeTempoResponse obj)
{
    _response = obj;
}

Answer 1

对于最小的更改，只需切换到Task.Delay和await结果即可。与其他三个await

一样，等待10秒后，这不再会阻止您的用户界面

FileResponse status;
do
{
    status = await Queries.FileStatus(id, analyze);
    status.ThrowIfUnsucessful();
    await Task.Delay(TimeSpan.FromSeconds(10));
} while (status.File.Status != "ready");
