Kullanımı:
using (var client = new TimeoutWebClient(TimeSpan.FromSeconds(10)))
{
return await client.DownloadStringTaskAsync(url).ConfigureAwait(false);
}
Sınıf:
using System;
using System.Net;
namespace Utilities
{
public class TimeoutWebClient : WebClient
{
public TimeSpan Timeout { get; set; }
public TimeoutWebClient(TimeSpan timeout)
{
Timeout = timeout;
}
protected override WebRequest GetWebRequest(Uri uri)
{
var request = base.GetWebRequest(uri);
if (request == null)
{
return null;
}
var timeoutInMilliseconds = (int) Timeout.TotalMilliseconds;
request.Timeout = timeoutInMilliseconds;
if (request is HttpWebRequest httpWebRequest)
{
httpWebRequest.ReadWriteTimeout = timeoutInMilliseconds;
}
return request;
}
}
}
Ama daha modern bir çözüm öneriyorum:
using System;
using System.Net.Http;
using System.Threading;
using System.Threading.Tasks;
public static async Task<string> ReadGetRequestDataAsync(Uri uri, TimeSpan? timeout = null, CancellationToken cancellationToken = default)
{
using var source = CancellationTokenSource.CreateLinkedTokenSource(cancellationToken);
if (timeout != null)
{
source.CancelAfter(timeout.Value);
}
using var client = new HttpClient();
using var response = await client.GetAsync(uri, source.Token).ConfigureAwait(false);
return await response.Content.ReadAsStringAsync().ConfigureAwait(false);
}
Bir moladan OperationCanceledException
sonra atar .
