C# - How to parse http header multipart

Question

I created a WCF Rest service and I am reading content sent by multipart/form data. However I get the contentdisposition and extra information. Is there a way to parse it like using HttpContext. I dont want dependency with asp...

If possible no use of external libraries, thirdparty dlls, etc... Unless its simple and consistent code I can implement.

This is just a stab in the dark, but have you tried this: OperationContext.Current.IncomingMessageHeaders. — Dan

No, but I tried HttpContext.Current.Request.Params["file"]; and I know it works but it creates dependency with IIS. — Devela

If the payload is an OData message (guessing from you tagging this as WCF Data Services), you could use ODataLib to parse it for you... — Vitek Karas MSFT

In case of parsing multipart data you should use some library/class or do it manually. There is no built-in functionality. Parser is pretty easy. But you can reuse some parser classes already written.

Try following project (MIT license) and file HttpMultipartParser.cs from this project:
