Vector.Equals Method

Definition

Namespace:

System.Windows

Assembly:

WindowsBase.dll

Compares two vectors for equality.

Overloads

Equals(Vector)	Compares two vectors for equality.
Equals(Vector, Vector)	Compares the two specified vectors for equality.
Equals(Object)	Determines whether the specified Object is a Vector structure and, if it is, whether it has the same X and Y values as this vector.

Remarks

A vector's X and Y properties are described using Double values. 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(Vector)

Compares two vectors for equality.

C#

public bool Equals(System.Windows.Vector value);

Parameters

value

Vector

The vector to compare with this vector.

Returns

Boolean

true if value has the same X and Y values as this vector; otherwise, false.

Examples

The following example shows how to use this method to check whether two Vector structures are equal.

C#

private Boolean equalsExample2()
{

    Vector vector1 = new Vector(20, 30);
    Vector vector2 = new Vector(20, 30);
    Boolean areEqual = false;

    // areEqual is True.  Both parameters are Vector structures, 
    // and they are equal.
    if (vector1.Equals(vector2))
    {
        areEqual = true;
    }

    return areEqual;
}

Remarks

A vector's X and Y properties are described using Double values. Because the value of a Double can lose precision when arithmetic operations are performed on it, a comparison between two Vector structures that are logically equal might fail.

Equals(Vector, Vector)

Compares the two specified vectors for equality.

C#

public static bool Equals(System.Windows.Vector vector1, System.Windows.Vector vector2);

Parameters

vector1

Vector

The first vector to compare.

vector2

Vector

The second vector to compare.

Returns

Boolean

true if the X and Y components of vector1 and vector2 are equal; otherwise, false.

Examples

The following example shows how to use this method to check whether two Vector structures are equal.

C#

private Boolean equalsExample1()
{

    Vector vector1 = new Vector(20, 30);
    Vector vector2 = new Vector(20, 30);
    Boolean areEqual = false;

    // areEqual is True
    if (Vector.Equals(vector1, vector2))
    {
      areEqual = true;
    }

    return areEqual;
}

Equals(Object)

Determines whether the specified Object is a Vector structure and, if it is, whether it has the same X and Y values as this vector.

C#

public override bool Equals(object o);

Parameters

o

Object

The vector to compare.

Returns

Boolean

true if o is a Vector and has the same X and Y values as this vector; otherwise, false.

Examples

The following example shows how to use this method to check whether a Vector and an Object are equal.

C#

private Boolean equalsExample2()
{

    Vector vector1 = new Vector(20, 30);
    Vector vector2 = new Vector(20, 30);
    Boolean areEqual = false;

    // areEqual is True.  Both parameters are Vector structures, 
    // and they are equal.
    if (vector1.Equals(vector2))
    {
        areEqual = true;
    }

    return areEqual;
}
