我将以下示例用于我的项目。

我们如何在“Windows.Web.Http.HttpClient” API中实现超时选项

Answer 1

您可以将CancellationTokenSource与超时一起使用。

        HttpClient client = new HttpClient();
        var cancellationTokenSource = new CancellationTokenSource(2000); //timeout
        try
        {
            var response = await client.GetAsync("https://test.example.com", cancellationTokenSource.Token);
        }
        catch (TaskCanceledException ex)
        {

        }

编辑 :
对于Windows.Web.Http.HttpClient，您应该使用AsTask()扩展方法:

HttpClient client = new HttpClient();
System.Threading.CancellationTokenSource source = new System.Threading.CancellationTokenSource(2000);
try
{
    client.GetAsync(new Uri("http://example.com")).AsTask(source.Token);
}
catch(TaskCanceledException ex)
{

}
