Size3D.Equality Operator

Compares two Size3D structures for equality. Two Size3D structures are equal if the values of their X, Y, and Z properties are the same.

Namespace:  System.Windows.Media.Media3D
Assembly:  PresentationCore (in PresentationCore.dll)

public static bool operator ==(
	Size3D size1,
	Size3D size2


Type: System.Windows.Media.Media3D.Size3D

The first Size3D structure to compare.

Type: System.Windows.Media.Media3D.Size3D

The second Size3D structure to compare.

Return Value

Type: System.Boolean
true if the X, Y, and Z components of size1 and size2 are equal; otherwise, false.

Because Double values can lose precision when arithmetic operations are performed on them, a comparison between two Size3D instances that are logically equal might fail.

The following example shows how to use the overloaded equality operator to check if two Size3D structures are equal.

                        // Checks if two Size3D structures are equal using the overloaded == operator.  
                        // Returns a Boolean. 

                        // Declaring Size3D structure without initializing x,y,z values
                        Size3D size1 = new Size3D();

                        // Declaring Size3D structure and initializing x,y,z values
                        Size3D size2 = new Size3D(5, 10, 15);
                        Boolean areEqual;

                        // Assigning values to size1
                        size1.X = 2;
                        size1.Y = 4;
                        size1.Z = 6;

                        // Checking for equality
                        areEqual = size1 == size2;

                        // areEqual is False 

                        // Displaying Results
                        syntaxString = " areEqual = size1 == size2;";
                        resultType = "Boolean";
						operationString = "Checking if two Size3D structures are equal";
						ShowResults(areEqual.ToString(), syntaxString, resultType, operationString);
