Visual Basic .NET编程基础：循环、数组与过程详解

1. 日期计算代码示例

在Visual Basic .NET中，有一段用于计算所选日期是星期几的代码。以下是 btnCalculate 按钮点击事件的代码：

Private Sub btnCalculate_Click(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles btnCalculate.Click
    Dim dtChosenDay As New DateTime _
        (cboYears.SelectedIndex + BASEYEAR, _
        cboMonths.SelectedIndex + 1, _
        cboDays.SelectedIndex + 1)
    Select Case dtChosenDay.DayOfWeek
        Case DayOfWeek.Sunday
            lblDayOfWeek.Text = "Sunday"
        Case DayOfWeek.Monday
            lblDayOfWeek.Text = "Monday"
        Case DayOfWeek.Tuesday
            lblDayOfWeek.Text = "Tuesday"
        Case DayOfWeek.Wednesday
            lblDayOfWeek.Text = "Wednesday"
