在C# WinForms应用程序中实现多语言设计,通常涉及以下几个步骤:
首先,你需要为每种支持的语言创建一个资源文件(通常是.resx
文件)。例如,你可以创建以下资源文件:
Resources.resx
(默认语言)Resources.de.resx
(德语)Resources.fr.resx
(法语)每个资源文件中包含所有需要翻译的文本字符串。
创建一个资源管理器类来管理这些资源文件。这个类将负责加载和访问资源文件中的字符串。
public class ResourceManager
{
private readonly Dictionary<string, ResourceSet> _resourceSets;
public ResourceManager()
{
_resourceSets = new Dictionary<string, ResourceSet>();
}
public void AddResourceSet(string cultureName, ResourceSet resourceSet)
{
_resourceSets[cultureName] = resourceSet;
}
public string GetString(string key)
{
if (_resourceSets.TryGetValue(Thread.CurrentThread.CurrentCulture.Name, out var resourceSet))
{
return resourceSet.GetString(key);
}
else if (_resourceSets.TryGetValue(Thread.CurrentThread.CurrentCulture.TwoLetterISOLanguageName, out var defaultResourceSet))
{
return defaultResourceSet.GetString(key);
}
else
{
return key; // Fallback to key if not found
}
}
}
在应用程序启动时,初始化资源管理器并加载所有语言资源文件。
public class Program
{
[STAThread]
public static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
var cultureInfo = new CultureInfo("en-US"); // Default culture
var resourceManager = new ResourceManager();
// Load all language resources
LoadResources(resourceManager, cultureInfo);
Application.Run(new MainForm());
}
private static void LoadResources(ResourceManager resourceManager, CultureInfo cultureInfo)
{
var assembly = Assembly.GetExecutingAssembly();
var baseName = new AssemblyName(assembly.GetName().Name).Name;
var cultureName = cultureInfo.Name;
var resourceName = $"{baseName}.Resources.{cultureName}";
var resourceSet = new ResourceSet(new ResourceManager(resourceName).GetResourceSet(CultureInfo.CurrentCulture));
resourceManager.AddResourceSet(cultureName, resourceSet);
// Add other cultures if needed
}
}
在WinForms应用程序中使用资源字符串时,通过资源管理器获取字符串。
public partial class MainForm : Form
{
private readonly ResourceManager _resourceManager;
public MainForm()
{
InitializeComponent();
_resourceManager = new ResourceManager();
}
private void button1_Click(object sender, EventArgs e)
{
label1.Text = _resourceManager.GetString("WelcomeMessage");
}
}
为了支持语言切换,你可以添加一个菜单项或按钮来切换当前文化,并重新加载资源文件。
private void switchLanguage(object sender, EventArgs e)
{
var selectedCulture = (CultureInfo)menuItem1.SelectedItem;
var cultureName = selectedCulture.Name;
var assembly = Assembly.GetExecutingAssembly();
var baseName = new AssemblyName(assembly.GetName().Name).Name;
var resourceName = $"{baseName}.Resources.{cultureName}";
var resourceSet = new ResourceSet(new ResourceManager(resourceName).GetResourceSet(CultureInfo.CurrentCulture));
_resourceManager.AddResourceSet(cultureName, resourceSet);
// Update UI elements with new language strings
label1.Text = _resourceManager.GetString("WelcomeMessage");
}
为了记住用户选择的语言,你可以将选择的语言存储在配置文件(如app.config
或web.config
)中,并在应用程序启动时读取它。
<configuration>
<appSettings>
<add key="UserLanguage" value="en-US"/>
</appSettings>
</configuration>
在应用程序启动时读取这个设置:
var cultureInfo = new CultureInfo((string)ConfigurationManager.AppSettings["UserLanguage"]);
var resourceManager = new ResourceManager();
LoadResources(resourceManager, cultureInfo);
通过以上步骤,你可以在C# WinForms应用程序中实现多语言设计。
