Important

Determines whether the two specified Matrix structures are identical.

public:
 static bool operator ==(System::Windows::Media::Matrix matrix1, System::Windows::Media::Matrix matrix2);

public static bool operator == (System.Windows.Media.Matrix matrix1, System.Windows.Media.Matrix matrix2);

static member ( = ) : System.Windows.Media.Matrix * System.Windows.Media.Matrix -> bool

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

Parameters

matrix1: Matrix

The first Matrix structure to compare.

matrix2: Matrix

The second Matrix structure to compare.

Returns

Boolean

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

Examples

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);
}

Remarks

Note

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.
