Gets or sets the number of milliseconds to wait before the request times out.
Assembly: System.Net.Http (in System.Net.Http.dll)
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 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.
