WebClient.OpenWriteAsync Method (Uri)
July 28, 2014
Opens a stream for writing data to the specified resource. This method does not block the calling thread.
Assembly: System.Net (in System.Net.dll)
The address parameter is Nothing.
There is not enough memory to continue the execution of the program.
The execution stack overflowed because it contains too many nested method calls.
A call was made to the Thread.Abort method to destroy a thread.
This method retrieves a writable stream that is used to send data to a resource. The stream is retrieved using thread resources that are automatically allocated from the thread pool. To receive notification when the stream is available, add an event handler to the OpenWriteCompleted event. When you close the stream, the thread blocks until the request is sent to address and a response is received.
This method does not block the calling thread while the stream is being opened.
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.
This method uses the POST command to upload an HTTP resource.
