Syntax
Parameters
- address
Returns
A System.IO.Stream used to write data to the resource.
Exceptions
Type Reason System.Net.WebException The absolute URI is not valid.
-or-
An error occurred while opening the stream.
Remarks
The WebClient.OpenWrite(string) 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 erload:System.Net.WebClient.OpenWriteAsync methods.
If the WebClient.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 WebClient.BaseAddress to form the absolute URI of the requested data. If the WebClient.QueryString property is not an empty string, it is appended to address.
This method uses the STOR command to upload an FTP resource. For an HTTP resource, the POST method is used.
