在运行时更改语言的应用程序

Question

我已经阅读了关于如何在.Net中创建多语言程序的教程，它运行良好，但在这里我需要一个让运行时的所有内容更容易的想法。 在用户点击语言时的运行时。我改变文化，以例如选择适当的语言：

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

，然后调用它设置文本为我的布局形式的函数：

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

，因为它似乎在查表当我为我的程序的每个组件设置文本时，它已经由.Net构建，与应该设置的属性相同。换句话说，“fileToolStripMenuItem1.Text”传递给GetString（）函数，并且结果应该设置为fileToolStripMenuItem1.Text，所以我不知道我该怎么做，甚至无法使用哪个工具来迭代在rm的每个属性上，然后通过反射或其他方法将密钥的值分配给密钥。也就是说，假设“fileToolStripMenuItem1.Text”是查找表中的关键字，值是“A”，那么我该如何做到这一点：将“fileToolStripMenuItem1.Text”的值为“A”赋值给fileToolStripMenuItem1.Text

我写了一些测试winforms应用程序，并尝试它，并可以更改控制文本属性动态地罚款。如果需要，您可以扩展此解决方案。

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

     //find control of form by its name 
     var controls = this.Controls.Find(controlName, true); 
     if (controls.Length > 0)

    string GetLocalizedResourceFile(CultureInfo ci)

     //for english language is default, so we don't have a need to add "en" part in path 
     return cultureCode != "en" ? string.Format("Resource1.{0}.resx", cultureCode) : "Resource1.resx";

    private void button1_Click(object sender, EventArgs e)
