這 Vector3D 棟建築的長度。

範例

以下範例說明如何取得結構的 Vector3D 長度。

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

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

length = vector1.Length;
// length is approximately equal to 53.85165

' Gets the length of a Vector3D.  
' Returns a Double.

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

length = vector1.Length
' length is approximately equal to 53.85165

備註

a Vector3D 的長度有時被稱為大小。
