Taswar Bhatti May 28, 2020 No Comments

In C#7 there are Expression Bodied Accessors which allows you to write getter and setters somewhat more functional way like lambda’ish. Let me show you an example. You may remember the old way of writing getter and setters like below.

public class Automobile 
{
  private string _brand;
  public string Brand 
  {
    get { return _brand; }
    set { _brand = value; }
  }
}

Taswar Bhatti May 6, 2020 No Comments

public Tuple<string, string> GetUserName(int userid)
{
    var firstname = db.GetFirstname(userid);
    var lastname = db.GetLastname(userid);
