The ReadWriteTimeout property 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.

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

The following code example shows how to set the ReadWriteTimeout property.

HttpWebRequest myReq =
myReq.ReadWriteTimeout = 100000;
