Compares two Vector3D structures for equality.
public:
static bool operator ==(System::Windows::Media::Media3D::Vector3D vector1, System::Windows::Media::Media3D::Vector3D vector2);public static bool operator == (System.Windows.Media.Media3D.Vector3D vector1, System.Windows.Media.Media3D.Vector3D vector2);static member ( = ) : System.Windows.Media.Media3D.Vector3D * System.Windows.Media.Media3D.Vector3D -> boolPublic Shared Operator == (vector1 As Vector3D, vector2 As Vector3D) As BooleanParameters
Returns
true if the X, Y, and Z components of vector1 and vector2 are equal; false otherwise.
Examples
The following example shows how to use the overloaded equality operator to check if two Vector3D structures are equal.
// Checks if two Vector3D structures are equal using the overloaded equality operator.
Vector3D vector1 = new Vector3D(20, 30, 40);
Vector3D vector2 = new Vector3D(45, 70, 80);
Boolean areEqual;
areEqual = (vector1 == vector2);
// areEqual is False
' Checks if two Vector3D structures are equal using the overloaded equality operator.
Dim vector1 As New Vector3D(20, 30, 40)
Dim vector2 As New Vector3D(45, 70, 80)
Dim areEqual As Boolean
areEqual = (vector1 = vector2)
' areEqual is False
Remarks
Two Vector3D structures are equal if the values of their X, Y, and Z properties are the same.
Vector3D values are described using Double values. Because the value of a Double can lose precision when operated upon, a comparison between two Vector3D values that are logically equal might fail.
