File Upload with ASP.NET

The Code Project

Back in the ASP world uploading files via a web page was a tricky problem. The problem was that due to the encryption type of the form used to submit the file from the clients browser receiving such files on the server side was a complex task. Data had to be retrieved as a safe byte array and decrypted before it could be used. Most of the people resorted to 3rd party DLLs,a few wrote their own DLLs and some even wrote purely ASP solutions to this problem using VBScript. Fortunately for us, .NET Framework SDK comes with a few classes that make uploading of the files simple from the web developer point of view.
