Question

I have a class library project. I have a property there like below. It’s not a read only property

 private   Int32 ABC  ;
public Int32   ABCD
        {
            set
            {
                this.ABC = value;
            }
            get
            {
                return this.ABC;
            }
        }

My question is, Is it necessary to declare the private variable for the same and the getter / setter ?

EDIT

I mean could it be like below ?

public Int32 ABCD {}

Answer 1

Automatic property declarations require the get; set; statements in the braces (which is what you had in your original question):

public Int32 ABCD { get; set; }

An empty property block isn’t valid.
