I have created a service to get user email. When I run a service I get user email. But, I want to authenticate user using API and for that user retrieve email , then how to do that?    

This is the code I have written to get email

[AllowAnonymous]

[HttpGet]

public HttpResponseMessage GetEmail(string username)

{

DotNetNuke.Entities.Users.UserInfo ui;

ui = DotNetNuke.Entities.Users.UserController.GetUserByName(username);

return Request.CreateResponse(HttpStatusCode.OK, ui.Email);

}

Help !

Example would be helpful
