建立對應的json字典對照表

{
"测试":"Test",
"语言":"Language",
"设置":"Set",
"中文(默认)":"Chinese (default)",
"英文":"English",
"标签测试":"Label Test",
"主界面-标题":"Main Title",
"组合框":"group box",
"选择框":"checkBox",
"单选按钮":"radioButton",
"列标题1":"ColumnHeader1",
"列标题2":"ColumnHeader2",
}

載入對應json文件

/// <summary>
/// 当前项目文件夹Debug\Language\参数文件夹
/// </summary>
/// <param name="language">配置文件所在文件夹名</param>
public static void LoadLanguage(TransType transType, string language = "")
{
    if (string.IsNullOrEmpty(language))

    }
 
    resources = new Dictionary<string, string>();
 
    string dir = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, 
                              string.Format("Language/{0}.json", language));
    if (File.Exists(dir))
    {
        LoadFile(transType, dir);
    }
}
 
/// <summary>
/// 配置文件加载
/// </summary>
/// <param name="path">配置文件绝对路径（包括文件本身）</param>
public static void LoadFile(TransType transType, string path)
{
    var content = File.ReadAllText(path, Encoding.UTF8);
    if (!string.IsNullOrEmpty(content))
    {
        var dict = JsonConvert.DeserializeObject<Dictionary<string, string>>(content);
        foreach (string key in dict.Keys)
        {
            if(transType == TransType.cn_en)
            {
                // 中文转英文
                if (!resources.ContainsKey(key))
                {
                    resources.Add(key, dict[key]);
                }
                else
                    resources[key] = dict[key];
            }
            else if(transType == TransType.en_cn)
            {

                var value = dict[key];
                if (!resources.ContainsKey(value))
                {

    }
}

設定視窗語言

public static void InitLanguage(Control control)
{
    SetControlLanguage(control);

    foreach (Control ctrl in control.Controls)
    {

    }
 
    //工具栏 或者菜单动态构建窗体或者控件的时候，重新对子控件进行处理
    control.ControlAdded += (sender, e) =>
    {
        InitLanguage(e.Control);
    };
}
 
/// <summary>
/// 控件及子控件翻译
/// </summary>
/// <param name="control">需要翻译的控件</param>
public static void SetControlLanguage(Control control)
{
    if (control is ComboBox)
    {
        // ComboBox 转换
        ComboBox combox = control as ComboBox;
        int curSelect = combox.SelectedIndex;
        string[] NewItems = new string[combox.Items.Count];
        for (int i = 0; i < combox.Items.Count; i++)
        {
            if (resources.ContainsKey(combox.Items[i].ToString()))
            {
                NewItems[i] = resources[combox.Items[i].ToString()];
            }
            else

        }
 
        combox.Text = (resources.ContainsKey(combox.Text)) ? resources[combox.Text] : combox.Text;
 
        combox.Items.Clear();
        combox.Items.AddRange(NewItems);
 
        combox.SelectedIndex = curSelect;
    }
     
    else if (control is TreeView)
    {
        //control is 其他控件或者特殊控件 如：TreeView
    }
    else if(control is ListView)

            }
        }
         
    }
    else

    }
}
