C 中英文切换

简介：

        一个项目如果要面对外国的客户时，需要语言切换。本文使用XML，XML是可扩展标记语言（Extensible Markup Language）的缩写，仅用于存储数据。

1.使用

1. 新建三个文件。文件的路径和格式需要和MultiLanguage类对应。
2. readme.xml存放的是记录选择的语言类型。
3. Chinese.xml是窗体控件对应的中文。
4. English.xml是窗体控件对应的英文。

2. 原理

1. 窗体的Name，需要根据当前窗体的实际名称进行更改。不管是任何窗体，按照如下格式即可。
2. 控件的Name和Text，根据实际情况填写。不管是任何控件，按照如何格式即可。

3.代码

1. 读取readme.xml的语言类型，加载对应的语言配置文件。
2. 通过菜单的Click事件，选择语言类型。
3. MultiLanguage类展示。

• 加载

 private void Form1_Load(object sender, EventArgs e) { LanguageInit(); } private void LanguageInit() { string lang = MultiLanguage.GetDefaultLanguage(); LanguageSwitch(this, lang); }

• 选择

 private void languageToolStripMenuItem_Click(object sender, EventArgs e) { ToolStripMenuItem menu = sender as ToolStripMenuItem; string lang = ""; if (menu == chineseToolStripMenuItem) { lang = Enum.GetName(typeof(enumLanguage), 0); } else if (menu == englishToolStripMenuItem) { lang = Enum.GetName(typeof(enumLanguage), 1); } LanguageSwitch(this, lang); } private void LanguageSwitch(Form form, string lang) { if (!MultiLanguage.LoadLanguage(form, lang)) { return; } MultiLanguage.SetDefaultLanguage(lang); if (lang == Enum.GetName(typeof(enumLanguage), 0)) { chineseToolStripMenuItem.Checked = true; englishToolStripMenuItem.Checked = false; } else if (lang == Enum.GetName(typeof(enumLanguage), 1)) { chineseToolStripMenuItem.Checked = false; englishToolStripMenuItem.Checked = true; } }
