C# Tips

I will give a few c# tips.

1) You can form objects via casting

class Tip1

    {

        public void Method1()

        {

            var entity = new Entity() { Name = "Mehmet", SureName = "Yoldaş" };

            var formedEntity = (FormedEntity)entity;

        }

    }

    public class FormedEntity

    {

        public string FullName { get; set; }

        public static explicit operator FormedEntity(Entity entity)

        {

            return new FormedEntity() { FullName = entity.Name + " " + entity.SureName };

        }

    }

    public class Entity

    {

        public string Name { get; set; }

        public string SureName { get; set; }

    }

2)  There is no nessesary null check operation when calling handler method. You could set empty delegate  to handler method.

    public delegate void MyEventHandler(object sender, int value);

        public event MyEventHandler Handle = delegate { };

        public void Method1() //use this method instead of Method2

        {

            Handle(this, -1);

        }

        public void Method2()

        {

       

            MyEventHandler handle = Handle;

            if (handle != null)

            {

                handle(this, -1);

            }

        }
3) If you do not use event args and sender information you should use directly method same as code below.

 public void method()

        {

            Button btn = new Button();

            btn.Click += btn_Click; //bad

            btn.Click += (o, a) => Save();//good

        }

        void Save()

        {

        }

        void btn_Click(object sender, EventArgs e)

        {

            Save();

        }
