Error

[mdemarco1234]

Hello,

I am getting an error when the file is posted. I am using WebApi and C#.  

"Unexpected end of MIME multipart stream. MIME multipart message is not complete". Code I have tried is below. Some of it is commented out but the latest is not. Tried all the code to no avail.

Regards,

Michael
