C# Winform 国际化

1、在Form的language属性选择中文，来制作中文界面

保存后，设置界面标题会变成如下所示，并且会出现一个zh-CN的资源文件，打开resx文件可看到相应内容

2、将Form的language属性改为英文，其余步骤如第1步，即可生成英文资源文件 

3、添加代码完成切换

    public partial class Form1 : Form
    {

        ComponentResourceManager resources = new ComponentResourceManager(typeof(Form1));
        // 遍历控件，并根据资源文件替换相应属性
        private void ApplyResource()
        {
            foreach (Control ctl in this.Controls)
            {
                resources.ApplyResources(ctl, ctl.Name); 
            }
            this.ResumeLayout(false);
            this.PerformLayout();
            resources.ApplyResources(this, "$this");
        } 

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            string s = System.Globalization.CultureInfo.InstalledUICulture.Name; //获取当前系统的语言
            Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo(s);
            ApplyResource();
        }

        private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            if (comboBox1.SelectedIndex == 0)
            {
                Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("zh-CN");
            }
            else
            {
                Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("en-GB");
            }
            ApplyResource();
        }
    }
}
