WebClient::OpenRead Method (Uri)
Opens a readable stream for the data downloaded from a resource with the URI specified as a Uri
Assembly: System (in System.dll)
The OpenRead method creates a Stream instance used to read the contents of the resource specified by the address parameter. This method blocks while opening the stream. To continue executing while waiting for the stream, use one of the OpenReadAsync 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 nullptr, it is appended to address.
This method uses the RETR command to download an FTP resource. For an HTTP resource, the GET method is used.
