Vector.Length 属性

定义

命名空间:

System.Windows

程序集:

WindowsBase.dll

获取此向量的长度。

public:
 property double Length { double get(); };

public double Length { get; }

member this.Length : double

Public ReadOnly Property Length As Double

属性值

Double

此向量的长度。

示例

以下示例演示如何使用此属性获取向量长度。

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

注解

矢量的长度有时称为数量级。
