{  

    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
