Size is part of the set of value types, including Point and Rectangle, that are used to define basic drawing geometry. It uses integers to represent horizontal and vertical extent (such as the width and height of a Rectangle).

In addition to being able to retrieve the Width and Height, you can determine whether the Size value is Empty (which means both the Width and Height are equal to 0).

As with the other fundamental value types in the framework, there is an equivalent floating-point structure called SizeF. Three conversion functions (Round(), Truncate(), and Ceiling()) are provided to allow you to convert from the float representation to the integer, and there is an operator that allows you to cast the other way. You can also convert to a Point.

You are also provided with addition, subtraction, and comparison operators.

Note that there is no intrinsic performance advantage in using the integer version of this type over the floating-point equivalent. As of v1.0 of the .NET Framework, most drawing functions are implemented in terms of the floating-point version anyway.

public struct Size {
// Public Constructors
   public Size(int width, int height);
   public Size(Point pt);
// Public Static Fields
   public static readonly Size Empty;  // = {Width=0, Height=0}
// Public Instance Properties
   public int Height{set; get; }
   public bool IsEmpty{get; }
   public int Width{set; get; }
// Public Static Methods
   public static Size Ceiling(SizeF value);
   public static Size Round(SizeF value);
   public static Size Truncate(SizeF value);
   public static Size operator -(Size sz1, Size sz2);
   public static Size operator +(Size sz1, Size sz2);
   public static bool operator !=(Size sz1, Size sz2);
   public static bool operator ==(Size sz1, Size sz2);
   public static explicit operator Point(Size size);
   public static implicit operator SizeF(Size p);
// Public Instance Methods
   public override bool Equals(object obj);  // overrides ValueType
   public override int GetHashCode();  // overrides ValueType
   public override string ToString();  // overrides ValueType
}
