access office 365 Onedrive files/folders in Asp.Net Web Forms Application not an MVC application

Hi all,

I want to create a file/Folder in my office 365 OneDrive account using the Asp.Net Web Forms Application not an MVC application.

I have tried with Office 365 Api's and REST Api's but when generating the AccessToken I am facing the problem...

I do not identify any reference forums regarding this requirement(creating files in Office 365 Onedrive using Asp.Net Web Forms Application not an MVC Application).

I do not know how to write the code to Get the Access token...

If any body will provide the code to get the AccessToken using Asp.Net Web Forms Application in C#/Vb.Net language is appreciated...or atleast any reference links (only related to Asp.Net Web Forms not MVC please)

Thanks

Hanife
