What I have tried:

I'm not able to convert pdf file to base64 string but file uploaded successfully when I open pdf file it showing 0kb file size. This same code works for an image but when I try to use to convert for pdf file it is not working. in my code I have created a method called 'NewBase64' in that I'm converting pdf file to base64 can any tell me where I'm gone wrong.

"I'm not able to convert pdf file to base64 string..."

Using the debugger, have you stepped through the code to find out why?
