HttpClient.Timeout Property

.NET Framework 4.5

Gets or sets the number of milliseconds to wait before the request times out.

Namespace:  System.Net.Http
Assembly:  System.Net.Http (in System.Net.Http.dll)

public TimeSpan Timeout { get; set; }

Property Value

Type: System.TimeSpan
Returns TimeSpan.
The number of milliseconds to wait before the request times out.


The timeout specified is less than or equal to zero and is not Infinite.


An operation has already been started on the current instance.


The current instance has been disposed.

The default value is 100,000 milliseconds (100 seconds).

A Domain Name System (DNS) query may take up to 15 seconds to return or time out. If your request contains a host name that requires resolution and you set Timeout to a value less than 15 seconds, it may take 15 seconds or more before a WebException is thrown to indicate a timeout on your request.

The same timeout will apply for all requests using this HttpClient instance. You may also set different timeouts for individual requests using a CancellationTokenSource on a task. Note that only the shorter of the two timeouts will apply.

supports a maximum timeout of 60 seconds on HTTP requests. Setting a Timeout value higher than 60 seconds is allowed, but the actual timeout is still limited to a maximum of 60 seconds.
