Struct in C# Example

C# > Types > Struct

A struct type is a value type and is typically used for representing lightweight objects (color, zip, point).

• cannot inherit from another struct or class
• can be instantiated without using a new operator.
• can implement an interface
• can contain fields, constructors, methods, operators and events, but
• if many members are required  you should make your type a class instead

Note:  Struct might be more efficient than a class in some scenarios. Using array of thousand of objects will be allocate more memory for referencing each object, so in this case, a struct would is more efficient and less expensive.






Example

        public struct strColor
        {
            public int r, g, b;
            public strColor(int p1, int p2, int p3)
            {
                r = p1;
                g = p2;
                b = p3;
            }
        }

       // Initialize using default and parameterized constructor

       strColor color1 = new strColor();
       strColor color2 = new strColor(10, 20, 30);

      // Declare object. It creates object without using the new  operator

       strColor color;

      //Initialize

       color.r = 10;
       color.g = 20;
       color.b = 30;
