Public ReadOnly Property LengthSquared As Double

プロパティ値

この Vector3D 構造体の長さの四角形。The square of the length of this Vector3D structure.

次の例は、 Vector3D構造体の長さの2乗を取得する方法を示しています。The following example shows how to get the square of the length of a Vector3D structure.

// Gets the square of the length of a Vector3D.  
// Returns a Vector3D.

Vector3D vector1 = new Vector3D(20, 30, 40);
Double lengthSq;

lengthSq = vector1.LengthSquared;
// lengthSq is equal to 2900
' Gets the square of the length of a Vector3D.  
' Returns a Vector3D.

Dim vector1 As New Vector3D(20, 30, 40)
Dim lengthSq As Double

lengthSq = vector1.LengthSquared
' lengthSq is equal to 2900

注釈

Vector3D長さは、"大きさ" と呼ばれることもあります。The length of a Vector3D is sometimes referred to as the magnitude.
