public void gotoActivity(Class activityClassReference)

    Intent i = new Intent(this,activityClassReference);

    public void StartAuthenticatedActivity(System.Type activityType)
    {
        var intent = new Intent(this, activityType);
        StartActivity(intent);
    }

    public void StartAuthenticatedActivity<TActivity>() where TActivity: Activity
    {
        StartAuthenticatedActivity(typeof(TActivity));
    }

You can then add in the where TActivity : YourBaseActivityis a base activity that you have created

I know the question may be outdated but I have a different approach, with an external class for a general call action towards any existing activity:

I know the question may be outdated but I have a different approach, with an external class for a general call action towards any existing activity:

public static class GeneralFunctions
    {
        public static void changeView(Activity _callerActivity, Type activityType)
        {
            ContextWrapper cW = new ContextWrapper(_callerActivity);
            cW.StartActivity(intent);
        }
    }

Button redirectButton = FindViewById<Button>(Resource.Id.RedirectButton);

redirectButton.Click += delegate
{
    GeneralFunctions.changeView(this, typeof(LoginView));
};
