DevExpress WinForm 控件汉化方法

使用DevExpress控件开发时，汉化一直是一个很纠结的问题，各种方法均存在很多不足，在此不作评论。
现将本人实际使用中找到的方法提出共享，多提宝贵意见。
一、本地化对象。DevExpress的文档中列出的是14个。

Product	Localizer Class	Resource String Enumeration
XtraBars	BarLocalizer	BarString
XtraCharts	ChartLocalizer	ChartStringId
XtraEditors	Localizer	StringId
XtraGauges	GaugeCoreLocalizer	GaugeCoreStringId
XtraGrid	GridLocalizer	GridStringId
XtraLayoutControl	LayoutLocalizer	LayoutStringId
XtraNavBar	NavBarLocalizer	NavBarStringId
XtraPivotGrid	PivotGridLocalizer	PivotGridStringId
XtraPrinting	PreviewLocalizer	PreviewStringId
XtraReports	ReportLocalizer	ReportStringId
XtraScheduler	SchedulerLocalizer	SchedulerStringId
XtraSpellChecker	SpellCheckerLocalizer	SpellCheckerStringId
XtraTreeList	TreeListLocalizer	TreeListStringId
XtraVerticalGrid	VGridLocalizer	VGridStringId

另外还有：

DevExpress.Accessibility.AccLocalizer	AccStringId
DevExpress.XtraRichEdit.Localization.XtraRichEditLocalizer	XtraRichEditStringId
DevExpress.XtraWizard.Localization.WizardLocalizer	WizardStringId
DevExpress.XtraScheduler.Localization.SchedulerExtensionsLocalizer	SchedulerExtensionsStringId
DevExpress.XtraRichEdit.Localization.RichEditExtensionsLocalizer	RichEditExtensionsStringId

二、资源字符串枚举。需要确切取得所有的Resource String Enumeration成员及其值（英语），才能汉化。首先可以到源码中查找，如可以在C:\Program Files (x86)\DevExpress 2011.2\Components\Sources\DevExpress.XtraBars\DevExpress.XtraBars中找到Localizer.cs文件，有一个protected override void PopulateStringTable()过程，里面的代码是加入枚举字符串的值：

AddString(BarString.None, "");

AddString(BarString.PopupMenuEditor, "Popup Menu Editor");

AddString(BarString.AddOrRemove, "&Add or Remove Buttons");

AddString(BarString.ResetBar, "Are you sure you want to reset the changes made to the '{0}' toolbar?");

AddString(BarString.ResetBarCaption, "Customize");

AddString(BarString.ResetButton, "&Reset Toolbar");

AddString(BarString.CustomizeButton, "&Customize ...");

AddString(BarString.ToolBarMenu, "&Reset$&Delete$!&Name$!Defau< style$&Text Only (Always)$Text &Only (in Menus)$" +

"Image &and Text$!Begin a &Group$&Visible$&Most recently used");

AddString(BarString.ToolbarNameCaption, "&Toolbar Name:");

AddString(BarString.NewToolbarCaption, "New Toolbar");

AddString(BarString.NewToolbarCustomNameFormat, "Custom {0}");

AddString(BarString.NewMenuName, "Main menu");

AddString(BarString.NewToolbarName, "Tools");

AddString(BarString.NewStatusBarName, "Status bar");

AddString(BarString.RenameToolbarCaption, "Rename Toolbar");

AddString(BarString.CustomizeWindowCaption, "Customization");

AddString(BarString.MenuAnimationSystem, "(System default)");

......

也就是说，如果你可以重新编译源码，可以直接在这里翻译后编译。当然本人未采用这种方法。但是不同的控件使用的程序文件名不太一致，或是位置不太一致，所以有的也不太好找，或是不全。后来发现每个Localizer 一般会提供一个CreateDefaultLocalizer.WriteToXml方法，但XtraPivotGrid控件的好象没有，还好又找到一个Localizer.Active.WriteToXml可能用，效果相同。

试着导出一看是这样的：

<?xml version="1.0" encoding="utf-8"?>

<root>

<data name="BarString.None">

<value>

</value>

</data>

<data name="BarString.PopupMenuEditor">

<value>Popup Menu Editor</value>

</data>

<data name="BarString.AddOrRemove">

<value>&Add or Remove Buttons</value>

</data>

<data name="BarString.ResetBar">

<value>Are you sure you want to reset the changes made to the '{0}' toolbar?</value>

</data>

<data name="BarString.ResetBarCaption">

<value>Customize</value>

</data>

<data name="BarString.ResetButton">

<value>&Reset Toolbar</value>

</data>

<data name="BarString.CustomizeButton">

<value>&Customize ...</value>

</data>

......

用这个方法导出所有字符串枚举名称及值到.XML文件中。

三、翻译。上面的内容有了，剩下就是翻译了，我相信大家都会想，不会这么全都重新开始吧，当然，原来可用资源应当用上才对。如官方汉化。我是这样做的，如下：

（1）在数据库建立一个表，包括name,EN(原文，英语)，CN(中文简体)，TW(中文繁体)等字段。将上述XML文件内容全部导入。

（2）编写一段代码。将官方汉化的资源文件的内容取出（当然是不全啦）。我写的是VB代码，谨供参考啦（如有需要C#请自己改一下吧）。

Private Sub SimpleButton1_Click(sender As System.Object, e As System.EventArgs) Handles SimpleButton1.Click

OpenFileDialog1.Filter = "resx文件|*.resx"

If OpenFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then

resxfilename = OpenFileDialog1.FileName

End If

rsxr = New ResXResourceReader(resxfilename)

If Not IsNothing(rsxr) Then

resxdt = getDTread("SELECT * FROM Localizer WHERE name LIKE '" & TextEdit1.Text.Trim & "%' AND CN='' ORDER BY ID")

‘getDTread是读取表过程。

Dim d As DictionaryEntry

Dim s As Integer = 0

Dim dtrow() As DataRow

Dim cr As Integer = -1

MemoEdit1.Text = ""

Dim str As String = ""

For Each d In rsxr

If InStr(d.Key.ToString, TextEdit1.Text.Trim) > 0 Then

dtrow = resxdt.Select("name ='" & d.Key.ToString & "'")

If dtrow.Length > 0 Then

cr = resxdt.Rows.IndexOf(dtrow(0))

If cr >= 0 Then

resxdt.Rows(cr).Item("CN") = d.Value.ToString()

s += 1

str += d.Key.ToString() + ":" + ControlChars.Tab + d.Value.ToString() + Chr(13) + Chr(10)

End If

End If

End If

Next d

MemoEdit1.Text = str

If s > 0 Then

getDTsave("Localizer", 1, resxdt.GetChanges)

‘getDTsave是提交表过程

End If

XXshow("共" & s.ToString.Trim & "行", Me)

MemoEdit1.Focus()

End If

rsxr.Close()

End Sub

在打开文件对话框中找到官方汉化包中的LocalizationRes.zh-CHS.resx 文件，把已经有的汉化内容存入数据库表中。可以同时将繁体中文（LocalizationRes.zh-CHT.resx）也取出存入，便于以后使用或用来参照，并且它还比简体中文内容多一些，但也缺很多。

这样处理之后，完成了一半左右。

（3）查询未经翻译的记录并导入到EXCEL文件。这样在参考繁体时可以块复制再简繁体转换，同时利于使用使用bing翻译，方法是将英文列块复制到WORD文档中，然使用WORD的全文翻译，之后在网页复制结果可成块粘贴到EXCEL中，之后再修改。

四、对象汉化代码。编写下列代码（示例）。重写GetLocalizedString方法。

Imports System.Resources

Imports System.Reflection

Imports DevExpress.XtraBars

Imports DevExpress.XtraBars.Localization

Public Class XLocallizerBar

Inherits DevExpress.XtraBars.Localization.BarLocalizer

Public Overrides ReadOnly Property Language() As String

Get

Return "Chinese"

End Get

End Property

Public Overrides Function GetLocalizedString(ByVal id As DevExpress.XtraBars.Localization.BarString) As String

Dim ret As String = ""

Select Case id

Case BarString.AddOrRemove : Return "添加或删除按钮(&A)" '&Add or Remove Buttons

Case BarString.BarAllItems : Return "(所有项)" '(All Items)

Case BarString.BarUnassignedItems : Return "(未设定项)" '(Unassigned Items)

Case BarString.CloseButton : Return "关闭" 'Close

Case BarString.CustomizeButton : Return "自定义(&C)..." '&Customize ...

Case BarString.CustomizeRibbon : Return "自定义功能区（&R）..." 'Customize the &Ribbon...

Case BarString.CustomizeWindowCaption : Return "自定义" 'Customization

Case BarString.HelpButton : Return "帮助" 'Help

Case BarString.MaximizeButton : Return "最大化" 'Maximize

Case BarString.RenameToolbarCaption : Return "重命名工具栏" 'Rename Toolbar

Case BarString.ResetBarCaption : Return "自定义" 'Customize

......

Case Else

ret = id.ToString

End Select

Return ret

End Function

End Class

其中的CASE语句从数据库查询自动生成,生成时带上原文，便于以后修改：

SELECT 'CASE '+name+': RETURN "' + CN + '" '''+EN as case语句

FROM Localizer where name LIKE 'BarString%'

ORDER BY name;

五、完成Localizer的替换。在主程序中加入下列代码：

DevExpress.Accessibility.AccLocalizer.Active = New XLocallizerAcc

DevExpress.XtraBars.Localization.BarLocalizer.Active = New XLocallizerBar

DevExpress.XtraCharts.Localization.ChartLocalizer.Active = New XLocallizerCharts

DevExpress.XtraEditors.Controls.Localizer.Active = New XLocallizerEditors

DevExpress.XtraGauges.Core.Localization.GaugesCoreLocalizer.Active = New XLocallizerGauges

DevExpress.XtraGrid.Localization.GridLocalizer.Active = New XLocallizerGrid

DevExpress.XtraLayout.Localization.LayoutLocalizer.Active = New XLocallizerLayout

DevExpress.XtraNavBar.NavBarLocalizer.Active = New XLocallizerNavBar

DevExpress.XtraPivotGrid.Localization.PivotGridLocalizer.Active = New XLocallizerPivotGrid

DevExpress.XtraPrinting.Localization.PreviewLocalizer.Active = New XLocallizerPrinting

DevExpress.XtraReports.Localization.ReportLocalizer.Active = New XLocallizerReports

DevExpress.XtraRichEdit.Localization.XtraRichEditLocalizer.Active = New XLocallizerRichEdit

DevExpress.XtraRichEdit.Localization.RichEditExtensionsLocalizer.Active = New XLocallizerRichEditExtensions

DevExpress.XtraScheduler.Localization.SchedulerLocalizer.Active = New XLocallizerScheduler

DevExpress.XtraScheduler.Localization.SchedulerExtensionsLocalizer.Active = New XLocallizerSchedulerExtensions

DevExpress.XtraSpellChecker.Localization.SpellCheckerLocalizer.Active = New XLocallizerSpellChecker

DevExpress.XtraTreeList.Localization.TreeListLocalizer.Active = New XLocallizerTreeList

DevExpress.XtraVerticalGrid.Localization.VGridLocalizer.Active = New XLocallizerVerticalGrid

DevExpress.XtraWizard.Localization.WizardLocalizer.Active = New XLocallizerWizard

总结。这种看上去麻烦，实际比较简单实用，后面发现错误时，可在源代码中搜索并替换，比较方便。当然其他方法也可以使用。由于本人是开发工程中完成的，代码也比较长，所以暂时不能提供完整的程序包，如果网友有需要，请在留言中留下QQ号码，可以提供源码。文中有哪些错漏，亦请各位指正。

在DEVEXPRESS使用中，发现功能确实不错，便运行速度还是很慢，不知哪位有好的办法吗？
