WP8里dll类库(SDK)实现多语言多主题_移动开发_编程开发_程序员俱乐部

近日在做一个sdk项目，因为要实现多语言切换，单独类库多语言这方面的实现不是很多，故整理如下。

1.添加AppResource.resx(英文)和AppResource-zh-CN.resx 

假设我们默认语言是英文，添加这两个文件。两个资源文件中均添加 UserCenter_Title 字段，并给其赋值。注意访问修饰符设置成public。

如果是要实现多主题的话，可相应添加图片等资源。

2.添加LocalizedStrings类

继承INotifyPropertyChanged并实现，最终代码可能如下

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 class="csharp keyword">public class AdeasygoLocalizedStrings : INotifyPropertyChanged     {         private static AppResource _localizedResources = new AppResource();           public AppResource AdeasygoLocalizedResource         {               get             {                   return _localizedResources;               }               set             {                   _localizedResources = value;                   NotifyPropertyChanged("AdeasygoLocalizedResource");               }           }           public event PropertyChangedEventHandler PropertyChanged;         public void NotifyPropertyChanged(string propertyName)         {             if (this.PropertyChanged != null)             {                 this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName));             }         }     }

3.修改AppResource.Designer.cs

这一步非常重要，添加ResourceManager属性的Set方法，以支持语言的动态切换：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 /// <summary>         ///   返回此类使用的缓存的 ResourceManager 实例。         /// </summary>         [global::System.ComponentModel.EditorBrowsableAttribute(global::System.ComponentModel.EditorBrowsableState.Advanced)]         public static global::System.Resources.ResourceManager ResourceManager {             get {                 if (object.ReferenceEquals(resourceMan, null)) {                     global::System.Resources.ResourceManager temp = new global::System.Resources.ResourceManager("Adeasygo.Community.Sdk.Resources.AppResource", typeof(AppResource).Assembly);                     resourceMan = temp;                 }                 return resourceMan;             }             set { resourceMan = value; }         }

4.控制语言(主题)切换

1 2 3 4 5 6 7 8 9 10 11 12 13 14 public static void Init(string lang = "en")         {             ResourceManager resManager;             switch (lang)             {                 case "zh":                     resManager = new ResourceManager("Sdk.Resources.AppResource-zh-CN", Assembly.Load("Sdk"));                     break;                 default:                     resManager = new ResourceManager("Sdk.Resources.AppResource", Assembly.Load("Sdk"));                     break;             }             AppResource.ResourceManager = resManager;         }

如此就实现了类库中动态的语言切换，图像资源等，也可以定义在resx中实现根据语言变化或者多主题切换。
