Visual studio 2010 数学，四舍五入变量？Visual basic

我正在为我的visual basic类编写一个程序，计算每磅罐头的价格。我正在运行程序，但我需要把美分凑成最接近的美元。如何在vb中实现这一点？可以将十进制变量四舍五入吗

如果这听起来很愚蠢，我很抱歉，我是个新手

这是我的密码

Public Class Form1

    Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click
        'Variables
        Dim cans As Integer
        Dim canPounds As Integer
        Dim canPoundTotal As Decimal
        Dim canWorth As Decimal = 0.75
        Dim cansNeeded As Integer

        'Conversions

        cans = Convert.ToInt32(txtGoal.Text)

        'Calculation

        canPounds = cans / 24

        canPoundTotal = canPounds * canWorth

        cansNeeded = 33000 - cans


        If cboNeed.SelectedIndex = 0 Then
            lblOutput.Text = cansNeeded.ToString + " cans need to be collected to reach your goal"

        ElseIf cboNeed.SelectedIndex = 1 Then
            lblOutput.Text = canPoundTotal.ToString("C") & " will be earned by collecting cans for recycling"


        End If




    End Sub


    Private Sub cboNeed_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboNeed.SelectedIndexChanged

        If cboNeed.SelectedIndex = 0 Then

            lblDesc.Text = "Target Goal Amount"
            btnCalculate.Text = "Find Target Amount of Cans"

        ElseIf cboNeed.SelectedIndex = 1 Then

            lblDesc.Text = "Cans Collected"
            btnCalculate.Text = "Find Amount Earned"

        End If

    End Sub
End Class

您可以使用函数：Math.Round（value）

因此如果结果是99.75美元。数学，上限是100美元吗？
