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.
public:
bool Equals(System::Windows::Vector value);public bool Equals (System.Windows.Vector value);override this.Equals : System.Windows.Vector -> boolPublic Function Equals (value As Vector) As BooleanParameters
- value
- Vector
The vector to compare with this vector.
Returns
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.
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.

- vector1
- Vector
The first vector to compare.
- vector2
- Vector
The second vector to compare.
Returns
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.
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)
public:

- o
- Object
The vector to compare.
Returns
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.
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;
