怎么在VB.NET中，提取系统日期中的后的 月和日 的位数

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim a As Short = Date.Now.Month

Dim b As Short = Date.Now.Day

MessageBox.Show(a)

MessageBox.Show(b)

End Sub

上面是获取月份以及天数

'======================

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim a As Short = Date.Now.Month

Dim b As Short = Date.Now.Day

Dim c, d As String

If a 0 AndAlso a 10 Then

c = "1位数"

Else

c = "2位数"

End If

If b 0 AndAlso b 10 Then

d = "1位数"

Else

d = "2位数"

End If

MessageBox.Show(c)

MessageBox.Show(d)

End Sub

这个是获取位数的

Dim differadd As Integer = 1 - ThisWeekDay '相差的天数（星期1与当前星期几相差的天数）

Dim MyAdd As New TimeSpan(differadd, 0, 0, 0)

Dim MyYear As Integer = Format(Now, "yyyy") '获取当前日期的年份

Dim MyMonth As Integer = Format(Now, "MM") '获取当前日期的月份

Dim MyDay As Integer = Format(Now, "dd") '获取当前日期是几号
