本篇文章主要介紹了分享兩種實(shí)現(xiàn)Winform程序的多語(yǔ)言支持的多種解決方案，小編覺(jué)得挺不錯(cuò)的，現(xiàn)在分享給大家，也給大家做個(gè)參考。一起跟隨小編過(guò)來(lái)看看吧。

二次封裝這些控件的目的是：1.暴露統(tǒng)一的屬性，便于直接遍歷并賦值（僅當(dāng)直接改變文本內(nèi)容語(yǔ)言時(shí)需要）；2.當(dāng)文本內(nèi)容或子控件文本內(nèi)容或新增子控件發(fā)生改變時(shí)，能夠根據(jù)語(yǔ)言緩存字典，快速直接的自我簡(jiǎn)繁轉(zhuǎn)換，無(wú)需再次遍歷；
五.LanguageHelper：語(yǔ)方轉(zhuǎn)換公共類(lèi)，與方案一原理相同，但相對(duì)方案一要簡(jiǎn)單很多，代碼如下：
public class LanguageHelper
{
#region 控件內(nèi)容簡(jiǎn)繁體轉(zhuǎn)換
/// <summary>
/// 設(shè)置控件的語(yǔ)言
/// </summary>
/// <param name="parent"></param>
public static void SetControlLanguageText(System.Windows.Forms.Control ctrl)
{
if (ctrl.HasChildren)
{
foreach (Control item in ctrl.Controls)
{
if (item is IMultiLanguageControl)
{
IMultiLanguageControl il = item as IMultiLanguageControl;
string value = GetLanguageText(il.DefaultLangText);
il.CurrentLangText = value;
}
if (item is IMultiLanguageContainerControl)
{
IMultiLanguageContainerControl lic = item as IMultiLanguageContainerControl;
Dictionary<object, string> dic = new Dictionary<object, string>();
foreach (var v in lic.DefaultLangTexts)
{
dic.Add(v.Key, GetLanguageText(v.Value));
}
lic.CurrentLangTexts = dic;
lic.ChildrenChanged += (s, e) =>
{
List<object> keyList = new List<object>();
foreach (var key in e.LangTexts.Keys)
{
keyList.Add(key);
}
keyList.ForEach(x =>
{
e[x] = GetLanguageText(e[x]);
});
keyList = null;
};
}
if (item.HasChildren)
{
SetControlLanguageText(item);
}
}
}
else
{
IMultiLanguageControl il = ctrl as IMultiLanguageControl;
string value = GetLanguageText(il.DefaultLangText);
il.CurrentLangText = value;
}
}
/// <summary>
/// 根據(jù)語(yǔ)言標(biāo)識(shí)符得到轉(zhuǎn)換后的值
/// </summary>
/// <param name="languageFlag"></param>
/// <param name="value"></param>
/// <returns></returns>
public static string GetLanguageText(string value)
{
string languageFlag = Thread.CurrentThread.CurrentUICulture.Name;
if (value == null || value == string.Empty)
{
return value;
}
switch (languageFlag.ToUpper())
{
case "ZH-CHT":
{
return ToTraditional(value);
}
default:
{
return ToSimplified(value);
}
}
}
/// <summary>
/// 簡(jiǎn)體轉(zhuǎn)換為繁體
/// </summary>
/// <param name="str">簡(jiǎn)體字</param>
/// <returns>繁體字</returns>
private static string ToTraditional(string str)
{
if (string.IsNullOrEmpty(str))
return str;
return ChineseConverter.Convert(str, ChineseConversionDirection.SimplifiedToTraditional);
}
/// <summary>
/// 繁體轉(zhuǎn)換為簡(jiǎn)體
/// </summary>
/// <param name="str">繁體字</param>
/// <returns>簡(jiǎn)體字</returns>
private static string ToSimplified(string str)
{
if (string.IsNullOrEmpty(str))
return str;
return ChineseConverter.Convert(str, ChineseConversionDirection.TraditionalToSimplified);
}
#endregion
}
Common.IsChsLanguage方法定義如下:
public static bool IsChsLanguage()
{
return System.Threading.Thread.CurrentThread.CurrentUICulture.Name.Equals("zh-CHS", StringComparison.OrdinalIgnoreCase);
}
多語(yǔ)言支持的容器類(lèi)控件的實(shí)現(xiàn)難點(diǎn)是：捕獲子控件文本內(nèi)容的改變，由于沒(méi)有現(xiàn)成的事件或方法，故需要通過(guò)其它的途徑來(lái)實(shí)現(xiàn)文本內(nèi)容改時(shí)能夠進(jìn)行處理。
以上就是本文的全部?jī)?nèi)容，有人可能會(huì)說(shuō)，為何不采用資源文件的形式，原因文章一開(kāi)頭就說(shuō)明了，是在原有的系統(tǒng)上，且不能改變?cè)械木幋a風(fēng)格，故才花了這么大的力氣來(lái)實(shí)現(xiàn)這個(gè)簡(jiǎn)繁轉(zhuǎn)換的功能，我公司經(jīng)領(lǐng)導(dǎo)確認(rèn)最終采用的方案二。文中若有不足，歡迎交流，謝謝！
注：控件的實(shí)現(xiàn)代碼都貼出來(lái)了，大家若需要的話，可以直接COPY走，另外為了系統(tǒng)安全，簡(jiǎn)繁體的系統(tǒng)截圖我就不貼出來(lái)了，大家可以自行測(cè)試。
