Upload Files to a Web Server - Simplest TLS Example

See more Upload Examples

This is the simplest example for uploading some files to a web server using SSL/TLS. the BlockingUpload call is synchronous and returns when the upload is finished (or failed).

A server-side C# example showing how to receive an upload is located at C# ASP.NET Code to Receive Upload
