32 | 33 | 34 |
35 | 36 | --- 37 | 38 | ### 静态使用 39 | 40 | 当你在项目中使用`.resx`文件作为语言文件时，你可以使用`Antelcat.I18N.Attributes.ResourceKeysOfAttribute`来自动生成资源键： 41 | 42 | ```csharp 43 | using Antelcat.I18N.Attributes; 44 | 45 | namespace MyProject 46 | 47 | //Auto generated class should be partial 48 | [ResourceKeysOf(typeof(My.Resource.Designer.Type))] 49 | public partial class LangKeys 50 | { 51 | } 52 | ``` 53 | 54 | 然后在你的`.xaml`文件中使用`x:Static`来为你的控件提供资源键 55 | 56 | 如果你已经在你的`.resx`文件中有 57 | 58 | ```xml 59 | 60 | 61 | 语言 62 | 63 | ``` 64 | 65 | 你可以像这样使用： 66 | 67 | ```xaml 68 | 69 | ``` 70 | 71 | 然后你可以使用这个键来绑定语言源 72 | 73 | ```xaml 74 | 75 | ``` 76 | 77 | 当你想要改变语言时，只需要调用 78 | 79 | ```csharp 80 | using System.Windows; 81 | 82 | I18NExtension.Culture = new CultureInfo("language code"); 83 | ``` 84 | 85 | 你可以看到文本在语言之间变化。 86 | 87 | --- 88 | 89 | ### 动态使用 90 | 91 | 有时你的源文本并不是在你的应用程序中定义的，而是从其他来源（如网络）接收到的，你可以使用`I18N`直接绑定文本。 92 | 93 | 如果你收到了一个像这样的json： 94 | 95 | ```json 96 | { 97 | "message": "This is a message" 98 | } 99 | ``` 100 | 101 | 并且你已经在`.resx`中将他翻译成了另一种语言 102 | 103 | ```xml 104 | 105 | 106 | 这是一条消息 107 | 108 | ``` 109 | 110 | 你肯定会设计一个`ViewModel`并且将他设置到属性`Message`中，你可以像这样绑定： 111 | 112 | ```xaml 113 | 114 | 115 | ``` 116 | 117 | 每当`Message`属性被改变或者语言源被改变时，文本都会自动更新。 118 | 119 | --- 120 | 121 | ### 多个文本组合和格式化 122 | 123 | 有些情况下，你需要将多个文本组合起来，或者对文本进行格式化，你可以使用`I18N`和`LanguageBinding`来实现。 124 | 125 | 如果你已经有了如下翻译的`.resx`文件： 126 | 127 | ```xml 128 | 129 | 130 | 当前的 {0} 是 {1} 131 | 132 | 133 | 语言 134 | 135 | 136 | 中文 137 | 138 | ``` 139 | 140 | 并且在`.xaml`中 141 | 142 | ```xaml 143 | 144 | 145 | 146 | 147 | 148 | 149 | 150 | 151 | ``` 152 | 153 | 此时 `I18N.Key` 是字符串的模板，其中的 `LanguageBinding` 和 `Binding` 会提供模板的参数，他们会被按顺序格式化成最终的文本。同时保持整体的响应性。 -------------------------------------------------------------------------------- /README.en.md: -------------------------------------------------------------------------------- 1 |

32 | 33 | 34 |
35 | 36 | 37 | ### Static using 38 | When using `.resx` language file in your project, you can 39 | automatically generate resource keys by using `Antelcat.I18N.Attributes.ResourceKeysOfAttribute`: 40 | 41 | ```csharp 42 | using Antelcat.I18N.Attributes; 43 | 44 | namespace MyProject 45 | 46 | //Auto generated class should be partial 47 | [ResourceKeysOf(typeof(My.Resource.Designer.Type))] 48 | public partial class LangKeys 49 | { 50 | } 51 | ``` 52 | 53 | Then in your `.xaml` file you can use `x:Static` to provide resource key to your control 54 | 55 | if you already have 56 | ```xml 57 | 58 | Language 59 | 60 | ``` 61 | in your `.resx` file, you can use it like this: 62 | ```xaml 63 | 64 | ``` 65 | 66 | Then you can use the key to bind the language source using `I18N` 67 | 68 | ```xaml 69 | 70 | ``` 71 | 72 | When you want to change the language, just call 73 | 74 | ```csharp 75 | using System.Windows; 76 | 77 | I18NExtension.Culture = new CultureInfo("language code"); 78 | ``` 79 | You can see the text is changing among the languages. 80 | 81 | --- 82 | 83 | ### Dynamic using 84 | 85 | Sometimes your source text is not defined in your application but received from other source like network, you can use `I18N` to bind the text directly. 86 | 87 | If you receive a json like this: 88 | ```json 89 | { 90 | "message": "This is a message" 91 | } 92 | ``` 93 | and you have translated it into another language in `.resx` like 94 | ```xml 95 | 96 | 这是一条消息 97 | 98 | ``` 99 | 100 | then you put the json into a `Message` property in your view model, you can bind it like this: 101 | 102 | ```xaml 103 | 104 | 105 | ``` 106 | 107 | Each time when the `Message` property is changed or the language source is changed, the text will be updated automatically. 108 | 109 | --- 110 | 111 | ### Combination and StringFormat 112 | 113 | Somebody may want to combine several language sources into one text, you can also use `I18N` and `LanguageBinding` to do this 114 | 115 | If you have source text in `.resx` file like this: 116 | ```xml 117 | 118 | 当前的 {0} 是 {1} 119 | 120 | 121 | 语言 122 | 123 | 124 | 中文 125 | 126 | ``` 127 | 128 | and in `.xaml` 129 | 130 | ```xaml 131 | 132 | 133 | 134 | 135 | 136 | 137 | 138 | 139 | ``` 140 | 141 | `I18N.Key` is the `string` template, content accepts `LanguageBinding` and `Binding` to provide the args. -------------------------------------------------------------------------------- /src/Avalonia/Avalonia/I18NExtension.cs: -------------------------------------------------------------------------------- 1 | using System.Collections.ObjectModel;
