winform 国际化多语言

要在C#中实现国际化，需要相关资源文件，比如要在一个软件中支持英文、中文、繁体三种语言，那么就必须有这三种语言的资源文件，这在C#中可以采用资源文件（后缀名为.resx）来实现，我们不妨定义英文资源文件名称为Resource.en-US.resx，中文资源文件名称一般默认为Resource.resx（也可以是Resource.zh-CN.resx），繁体资源文件名称为：Resource.zh-CHT.resx，三种资源文件所涉及的ID都应该是一样的（这对于其他更多的资源文件均是一样的），只不过是展示的名称不同罢了。

 1.下面是多语言类，放到跟窗体一个程序集下：

（

SetLang(string lang, Form form, Type formType) 设置语言根据实际项目去设置语言

）

2.在选择语言的窗体页面选择时，设置语言

// 中文简体： zh-CN  英文：en-US 繁体：zh-CHT
 ChangLanguage.SetLang("zh-CN", this, typeof(窗体名称));

 

 3. 在每个窗体的 _Load(object sender, EventArgs e)方法中加入以下代码：

ChangLanguage.SetLang(this, typeof(窗体名称));
