Matrix.Equality Operator

Determines whether the two specified Matrix structures are identical.

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

public static bool operator ==(
	Matrix matrix1,
	Matrix matrix2
)

Parameters

matrix1
Type: System.Windows.Media.Matrix
The first Matrix structure to compare.
matrix2
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.

NoteNote

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);

}
