Question

我正在编写一个月历样式的控件，并需要显示一个字符串，指示今天的日期。因此，在英语文化的机器上，它会显示 Today: 11/02/2009 。

如果使用不同的文化，比如说法国文化，那么我会使用法语的“今天”（Aujourd'hui）。

.NET平台是否将此单词公开作为文化信息的一部分，以便我可以自动检索它？我找不到任何公开的东西，但可能我没有找到正确的地方。

Answer 1

旧但依然有用（多老？VB6 老）。

基本上，Windows会在Comctl32.dll中保留“今天”的本地化版本。您可以使用loadstringex调用找到它。

Private Const IDM_TODAY As Long = 4163
Private Const IDM_GOTODAY As Long = 4164

Public Function GetTodayLocalized(ByVal LocaleId As Long) As String
    Static hComCtl32 As Long
    Static hComCtl32Initialized As Boolean
    Static hComCtl32MustBeFreed As Boolean

    Dim s As String

    If Not hComCtl32Initialized Then
        hComCtl32 = GetModuleHandle("Comctl32.dll")
        If hComCtl32 <> 0 Then
            hComCtl32MustBeFreed = False
            hComCtl32Initialized = True
        Else
            hComCtl32 = LoadLibrary("Comctl32.Dll")
            If Not hComCtl32 = 0 Then
                hComCtl32MustBeFreed = True
                hComCtl32Initialized = True
            End If
        End If
    End If

    If hComCtl32Initialized = False Then
        s = "Today"
    Else
        s = LoadStringEx(hComCtl32, IDM_TODAY, LocaleId)
        If s = "" Then
            s = "Today"
        End If
    End If

    If hComCtl32MustBeFreed Then
        FreeLibrary hComCtl32
        hComCtl32MustBeFreed = False
        hComCtl32Initialized = False
        hComCtl32 = 0
    End If

    s = Replace(s, "&", "")
    If Right(s, 1) = ":" Then
        s = Left(s, Len(s) - 1)
    End If

    GetTodayLocalized = s
End Function

Answer 2

这是一个相当全面的 .Net 本地化概述。

简而言之，DateTime结构的方法将根据系统区域设置格式化日期。您可以通过指定自己的区域设置来覆盖默认区域设置。

Edit: Sorry, I misread your question. No, there is no such thing. You could use a translation site to get the translations of Today that you need to support, and keep them in a dictionary in your code. Upon closer examination, though, I would not recommend this at all, since the resulting string "Today: xx/xx/xxx" may feel awkward in other languages. While the German version: "Heute: 11.2.2009", or the French "Aujourd hui: 11.2.2009" seem to work ok in a calendar, I can t say for Chinese or Japanese. This illustrates the issues that you can run into when you think localization is just translation.
