vb中水准记录与计算代码

在Visual Basic (VB) 中，水准记录通常用于处理测量数据，比如高度差、水平距离等。以下是一个简单的示例，展示了如何创建一个类来存储测量点以及计算高程差：

Public Class LevelRecord
    Private _pointName As String
    Private _elevation1 As Double
    Private _elevation2 As Double

    ' 构造函数
    Public Sub New(pointName As String, elevation1 As Double, elevation2 As Double)
        Me._pointName = pointName
        Me._elevation1 = elevation1
        Me._elevation2 = elevation2
    End Sub

    ' 记录数据属性
    Property PointName() As String
        Get
            Return _pointName
        End Get
        Set(value As String)
            _pointName = value
        End Set
    End Property

    Property Elevation1() As Double
        Get
            Return _elevation1
        End Get
        Set(value As Double)
            _elevation1 = value
        End Set
    End Property

    Property Elevation2() As Double
        Get
            Return _elevation2
        End Get
        Set(value As Double)
            _elevation2 = value
        End Set
    End Property

    ' 计算高程差
    Function HeightDifference() As Double
        Return Math.Abs(_elevation1 - _elevation2)
    End Function
End Class

你可以通过这样的类来操作测量数据，例如：

Dim record1 As New LevelRecord("A", 100, 150)
Dim record2 As New LevelRecord("B", 140, 170)

Dim diff1 = record1.HeightDifference()
Dim diff2 = record2.HeightDifference()

Console.WriteLine("Point A to B height difference: " & diff1)
Console.WriteLine("Point B to C height difference: " & diff2)
