Matrix.Equals Method (Matrix)


Determines whether the specified Matrix structure is identical to this instance.

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

public bool Equals(
	Matrix value


Type: System.Windows.Media.Matrix

The instance of Matrix to compare to this instance.

Return Value

Type: System.Boolean

true if instances are equal; 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);
