The address parameter is a null reference (Nothing in Visual Basic).
The URI formed by combining BaseAddress and address is invalid.
An error occurred while downloading the resource.
The method has been called simultaneously on multiple threads.
This method retrieves the specified resource. After it downloads the resource, the method uses the encoding specified in the Encoding property to convert the resource to a String. This method blocks while downloading the resource. To download a resource and continue executing while waiting for the server's response, use one of the DownloadStringAsync 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.
This method uses the RETR command to download an FTP resource. For an HTTP resource, the GET method is used.
