我在這裏有一些問題,我不太清楚如何處理它。如果你能導致我在正確的方向,這將不勝感激:'公共函數'沒有類型參數,所以不能有類型參數。 VB.NET
Private Function Convert2YearTo4Year(ByVal str_DTG2Year As String) As String
Dim str_sys4Year As String
Dim i_sys2Year As Integer
Dim i_sys2Century As Integer
str_sys4Year = Right(Str$(Of Date), 4)
i_sys2Year = Val(Right(str_sys4Year, 2)) 'value of system 2-digit yr
i_sys2Century = Val(Left(str_sys4Year, 2)) 'value of system 2-digit century
If Val(str_DTG2Year) < i_sys2Year And i_sys2Year - Val(str_DTG2Year) > 50 Then 'next century
Convert2YearTo4Year = Trim$(Str$(i_sys2Century + 1) + str_DTG2Year)
ElseIf Val(str_DTG2Year) > i_sys2Year And Val(str_DTG2Year) - i_sys2Year > 50 Then 'prev century
Convert2YearTo4Year = Trim$(Str$(i_sys2Century - 1) + str_DTG2Year)
Else
Convert2YearTo4Year = Trim$(Str$(i_sys2Century) + str_DTG2Year) 'current century
End If
End Function
