Question

我已经阅读了有关如何在.Net中创建多语言程序的教程，并且它运行良好，但在这里我需要一个想法，使运行时的所有内容更容易。在运行时，用户单击该语言。我将文化改为选择的正确语言，例如：

Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("en");

然后调用一个函数，为我的表单布局设置Text：

private System.Resources.ResourceManager rm;
fileToolStripMenuItem1.Text =  rm.GetString("fileToolStripMenuItem1.Text");
settingsToolStripMenuItem.Text = rm.GetString("settingsToolStripMenuItem.Text");

因为看起来我在为程序的每个组件设置文本时由.Net构建的查找表等于应该设置的属性。换句话说，“fileToolStripMenuItem1.Text”传递给GetString（）函数，结果应该设置为fileToolStripMenuItem1.Text，所以我不知道我该怎么做，甚至不知道哪个工具可以迭代在rm的每个属性上，然后通过反射或其他东西将键的值赋给键。也就是说，假设“fileToolStripMenuItem1.Text”是查找表中的键，值为“A”，那么我该怎么做呢：将“fileToolStripMenuItem1.Text”的值“a”分配给fileToolStripMenuItem1.Text

我已经编写了一些测试winforms应用程序并尝试它并可以动态更改控件Text属性。如果需要，您可以扩展此解决方案。

            InitializeComponent();
        }

    //main logic of switching language of UI
    void ChangeCulture_Handler(CultureInfo culture)
    {
        //getting relative path of resource file for specific culture
        var resourcePath = GetLocalizedResourceFile(culture);
        //initialize new reader of resource file
        var reader = new ResXResourceReader(resourcePath);
        //getting enumerator
        var resourceEnumerator = reader.GetEnumerator();
        //enumerate each record in resource file
        while (resourceEnumerator.MoveNext())
        {
            string resKey = Convert.ToString(resourceEnumerator.Key);
            //we can add here some check if need 
            //(for example if in resource file exists not only controls resources with format <Control Name>.<Property>
            //if( resKey.Split(new char[] { '.' }, StringSplitOptions.RemoveEmptyEntries).Length == 2) 
            string resValue = Convert.ToString(resourceEnumerator.Value);
            //actually update property
            UpdateControl(resKey, resValue);

    }

    //main logic of updating property of one control
    private void UpdateControl(string resKey, string resValue)

        var controlName = strs[0];
        var controlProp = strs[1];

        //find control of form by its name
        var controls = this.Controls.Find(controlName, true);

        {
            //select first control
            var control = controls[0];
            //getting type of it
            var t = control.GetType();
            //getting property
            var props = t.GetProperty(controlProp);
            if (props != null)
            {
                //setting localized value to property
                props.SetValue(control, resValue, null);

        return cultureCode != "en" ? string.Format("Resource1.{0}.resx", cultureCode) : "Resource1.resx";
    }
