ExceptionCondition
WebException

The URI formed by combining BaseAddress, and address is invalid.

-or-

An error occurred while opening the stream.

The OpenWrite method returns a writable stream that is used to send data to a resource. This method blocks while opening the stream. To continue executing while waiting for the stream, use one of the OpenWriteAsync methods.

If the BaseAddress property is not an empty string ("") and address does not contain an absolute URI, address must be a relative URI that is combined with BaseAddress to form the absolute URI of the requested data. If the QueryString property is not an empty string, it is appended to address.
