Hi All,

Im trying to creating user and assign them to a role in dnn using c#, what i have keeps throwing object reference exception and un-enable to create the user. The Role that i need to assign the user is coming from a query string. when ever i execute the code, it doesnt insert into the user table and its gives the error below. Please i need your help if there is something i'm missing.

Thanks
