推荐答案

此代码将但是如果它不超过28，它将不包含当前日期，如果你不需要保存这个适合你的日期。

This code will work but it will not contain the current date if it's bigger than 28, if you don't require to save the date this will work for you.

DateTimePicker1.Format = DateTimePickerFormat.Custom
    DateTimePicker1.CustomFormat = "MMMM yyyy"
    DateTimePicker1.ShowUpDown = True
    Dim getdate As String = My.Computer.Clock.LocalTime.Date.Day
    If getdate > 28 Then
        DateTimePicker1.Value = DateTimePicker1.Value.AddDays(-3)
    End If
