Object reference not set to instance of an object, While using Url.Action() method

Question

I am getting error: object reference not set to an instance of an object in this line of code in my Controller class method:

var ChangeEmailUrl = Url.Action("ChangeEmailConfirmation", "ManageAccount");

My objective is to get a URL path to an action 'ChangeEmailConfirmation' in controller 'ManageAccount'. The string link returned by the Url.Action() method would be sent in an email.

Also, I would like to know if there is any other way to get URL link. Any light on solving this problem would be appreciated.

Answer 1

If you wanted to get an absolute url (http://localhost:8385/MyController/DoThis):

  var ChangeEmailUrl = Url.Action("DoThis", "MyController",null,Request.Url.Scheme,null)

you can try with urlhelper or htmlhelper
