Vector.Length 屬性

定義

得到這個向量的長度。

public:
 property double Length { double get(); };
public double Length { get; }
member this.Length : double
Public ReadOnly Property Length As Double

屬性值

這個向量的長度。

範例

以下範例說明如何利用此特性取得向量長度。

private Double lengthExample()
{  

    Vector vector1 = new Vector(20, 30);

    // Get the length of the vector.
    // length is approximately equal to 36.0555
    Double lengthResult = vector1.Length;

    return lengthResult;
}
Private Function lengthExample() As Double

    Dim vector1 As New Vector(20, 30)

    ' Get the length of the vector.
    ' length is approximately equal to 36.0555
    Dim lengthResult As Double = vector1.Length

    Return lengthResult

End Function

備註

向量的長度有時也被稱為大小。
