Question

i have a structure defined, which contains a public field and a public property named _one and One respectively, now i instantiate the struct in the main function (not creating new object), and called the Property from the struct, i am getting the compile time error saying use of unassigned local variable One, however when i called the field _one, it works pretty expected here what i am doing:

 public struct myStruct
    {
        public int _one;
        public int One
        {
            get { return _one; }
            set { _one = value; }
        }
        public void Display()
        {
            Console.WriteLine(One);
        }
    }



static void Main(string[] args)
        {

            myStruct _struct;
            _struct.One = 2; // Does not works
            _struct._one = 2; // Works fine
        }

can anyone explain whats the reason behind this, could not understand the concept.

You need to initialize the struct in order for the property to be accessible – _struct has a default value otherwise:

myStruct _struct = new myStruct(); 

By the way – mutable value types are evil.
