WebClient.OpenReadAsync Method (Uri)
Opens a readable stream to the specified resource.
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 the specified resource using the GET method. The resource is downloaded asynchronously. If the AllowReadStreamBuffering property is true, then the OpenReadCompleted event is raised once the entire response stream has been received and buffered into memory. Otherwise, the OpenReadCompleted event is raised as soon as the response stream is available for reading even if all data has not yet arrived.
You can use the CancelAsync method to cancel asynchronous operations that have not completed.
If the BaseAddress property is not an empty string and the address does not contain an absolute URI, the address must be a relative URI that is combined with BaseAddress to form the absolute URI of the requested data.
