Matrix.Equality Operator (Matrix, Matrix)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Determines whether the two specified Matrix structures are identical.

Namespace:   System.Windows.Media
Assembly:  WindowsBase (in WindowsBase.dll)

Public Shared Operator = (
	matrix1 As Matrix,
	matrix2 As Matrix
) As Boolean


Type: System.Windows.Media.Matrix

The first Matrix structure to compare.

Type: System.Windows.Media.Matrix

The second Matrix structure to compare.

Return Value

Type: System.Boolean

true if matrix1 and matrix2 are identical; otherwise, false.


A Matrix stores its values as doubles. Because the value of a Double can lose precision when arithmetic operations are performed on it, a comparison between two Double structures that are logically equal might fail.

The following example shows how to check two Matrix structures for equality.

private void equalityExample()

    Matrix matrix1 = new Matrix(5, 10, 15, 20, 25, 30);
    Matrix matrix2 = new Matrix(5, 10, 15, 20, 25, 30);

    Boolean result;

    // result is true.
    result = (matrix1 == matrix2);            

    // result is false.
    result = (matrix1 != matrix2);
