C#的Winform多语言实现(resx文件)
1. 简体中文
2. 繁体中文
3. 英文
下面子丰介绍一下实现的过程:
1. 为每个窗口创建相应语言的resx文件。子丰以英文为例,右键->添加->新建项->资源文件,文件名为窗口名.en-US,如上面的两个窗口,分别为LoginForm.en-US.resx和PasswordForm.en-US.resx。简体中文为LoginForm.zh-CN.resx和PasswordForm.zh-CN.resx,繁体中文为LoginForm.zh-CHT.resx和PasswordForm.zh-CHT.resx。下面给出LoginForm.en-US.resx文件的截图。
2. 在项目的Properties的Settings.settings中添加变量DefaultLanguage,用于保存当前设置的默认语言。当下次启动程序时,会读取该变量,从而将程序的语言设置为上次程序关闭时的语言。
3. 创建一个静态类(MultiLanguage.cs)用于编写与切换语言相关的变量和代码。
(1)变量DefaultLanguage,用于保存当前默认语言
(2)函数SetDefaultLanguage修改当前默认语言
/// <summary> /// 修改默认语言 /// </summary> /// <param name="lang">待设置默认语言</param> public static void SetDefaultLanguage(string lang) { System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo(lang); DefaultLanguage = lang; Properties.Settings.Default.DefaultLanguage = lang; Properties.Settings.Default.Save(); }
(3)函数LoadLanguage用于加载语言或切换语言
/// <summary> /// 加载语言 /// </summary> /// <param name="form">加载语言的窗口</param> /// <param name="formType">窗口的类型</param> public static void LoadLanguage(Form form, Type formType) { if (form != null) { System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(formType); resources.ApplyResources(form, "$this"); Loading(form, resources); } } /// <summary> /// 加载语言 /// </summary> /// <param name="control">控件</param> /// <param name="resources">语言资源</param> private static void Loading(Control control, System.ComponentModel.ComponentResourceManager resources) { if (control is MenuStrip) { //将资源与控件对应 resources.ApplyResources(control, control.Name); MenuStrip ms = (MenuStrip)control; if (ms.Items.Count > 0) { foreach (ToolStripMenuItem c in ms.Items) { //遍历菜单 Loading(c, resources); } } } foreach (Control c in control.Controls) { resources.ApplyResources(c, c.Name); Loading(c, resources); } } /// <summary> /// 遍历菜单 /// </summary> /// <param name="item">菜单项</param> /// <param name="resources">语言资源</param> private static void Loading(ToolStripMenuItem item, System.ComponentModel.ComponentResourceManager resources) { if (item is ToolStripMenuItem) { resources.ApplyResources(item, item.Name); ToolStripMenuItem tsmi = (ToolStripMenuItem)item; if (tsmi.DropDownItems.Count > 0) { foreach (ToolStripMenuItem c in tsmi.DropDownItems) { Loading(c, resources); } } } }
4. 在主窗口的Load事件中读取Properties.Settings.Default.DefaultLanguage,并将ComboBox赋值为当前默认语言,即简体中文、繁体中文或英文。
private void LoginForm_Load(object sender, EventArgs e) { //设置combobox的值 string language = Properties.Settings.Default.DefaultLanguage; if (language == "zh-CN") { languageTxt.Text = "简体中文(默认)"; } else if (language == "zh-CHT") { languageTxt.Text = "繁體中文"; } else if (language == "en-US") { languageTxt.Text = "English"; } }
5. 在每个窗口的Load事件中调用函数MultiLanguage.LoadLanguage,使窗口在出现时即显示为当前默认语言。
private void PasswordForm_Load(object sender, EventArgs e) { //加载语言 MultiLanguage.LoadLanguage(this, typeof(PasswordForm)); }
6. 编写用于切换语言的ComboBox的SelectedIndexChanged事件,使得当用户选择对应的语言时,程序会切换到该语言。
//切换语言 private void languageTxt_SelectedIndexChanged(object sender, EventArgs e) { languageTxt.Enabled = false; if (languageTxt.Text == "简体中文(默认)") { //修改默认语言 MultiLanguage.SetDefaultLanguage("zh-CN"); //对所有打开的窗口重新加载语言 foreach (Form form in Application.OpenForms) { LoadAll(form); } } else if (languageTxt.Text == "繁體中文") { //修改默认语言 MultiLanguage.SetDefaultLanguage("zh-CHT"); //对所有打开的窗口重新加载语言 foreach (Form form in Application.OpenForms) { LoadAll(form); } } else if (languageTxt.Text == "English") { //修改默认语言 MultiLanguage.SetDefaultLanguage("en-US"); //对所有打开的窗口重新加载语言 foreach (Form form in Application.OpenForms) { LoadAll(form); } } languageTxt.Enabled = true; } private void LoadAll(Form form) { if (form.Name == "LoginForm") { MultiLanguage.LoadLanguage(form, typeof(LoginForm)); } else if (form.Name == "PasswordForm") { MultiLanguage.LoadLanguage(form, typeof(PasswordForm)); } }
