Matrix.Equals Method

Definition

Namespace:

System.Windows.Media

Assembly:

WindowsBase.dll

Determines whether the two specified Matrix structures have the same values.

Overloads

Equals(Object)	Determines whether the specified Object is a Matrix structure that is identical to this Matrix.
Equals(Matrix)	Determines whether the specified Matrix structure is identical to this instance.
Equals(Matrix, Matrix)	Determines whether the two specified Matrix structures are identical.

Examples

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

C#

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

Huomautus

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.

Equals(Object)

Determines whether the specified Object is a Matrix structure that is identical to this Matrix.

C#

public override bool Equals(object o);

Parameters

o

Object

The Object to compare.

Returns

Boolean

true if o is a Matrix structure that is identical to this Matrix structure; otherwise, false.

Examples

{

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

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

Equals(Matrix)

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

C#

public bool Equals(System.Windows.Media.Matrix value);

Parameters

value

Matrix

The instance of Matrix to compare to this instance.

Returns

Boolean

true if instances are equal; otherwise, false.

Examples

{

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

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