The URI of the resource to receive the string. For Http resources, this URI must identify a resource that can accept a request sent with the POST method, such as a script or ASP page.
The string to be uploaded.
Return ValueA String containing the response sent by the server.
Before uploading the string, this method converts it to a Byte array using the encoding specified in the Encoding property. This method blocks while the string is transmitted. To send a string and continue executing while waiting for the server's response, use one of the UploadStringAsync 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 STOR command to upload an FTP resource. For an HTTP resource, the POST method is used.
This member outputs trace information when you enable network tracing in your application. For more information, see Network Tracing.

Dim reply As String = client.UploadString(address, data) ' Disply the server's response. Console.WriteLine(reply) End Sub
