Returning values

Question

I have a method like below

public List<aspnet_Roles> GetAllRoles()
{
  var rolesList = _dbProfile.aspnet_Roles.ToList();
  return rolesList;
}

In this method first all the roles from database (LINQ to SQL) has been retrieved and assigned to a variable rolesList of type var.

I want to know if returning value directly is better instead of assigning it to other variables first and then returning it.

Is the below method is better than above version:

public List<aspnet_Roles> GetAllRoles()
        {
            return _dbProfile.aspnet_Roles.ToList();
        }

Will the above two methods compile in IL as same or second version is better? Second version doesn't have the unnecessary variable declaration.

Answer 1

First method will help you with debugging. Right now, AFAIK, there is no way to watch return value of a method while debugging.

Other than that, there is no difference.
