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

member ReadWriteTimeout : int with get, set

Property Value

Type: System.Int32
The number of milliseconds before the reading or writing times out. The default value is 300,000 milliseconds (5 minutes).

ExceptionCondition
InvalidOperationException

ArgumentOutOfRangeException

The value specified for a set operation is less than or equal to zero and is not equal to Timeout.Infinite.

The ReadWriteTimeout is used when writing to the stream returned by the GetRequestStream method or reading from the stream returned by the GetResponseStream method.

Specifically, the ReadWriteTimeout property controls the time-out for the Read method, which is used to read the stream returned by the GetResponseStream method, and for the Write method, which is used to write to the stream returned by the GetRequestStream method. If the time-out period is exceeded, the calling method throws a WebException with WebExceptionStatus set to Timeout.

To specify the amount of time to wait for the request to complete, use the Timeout property.
