如何覆盖Resources.Designer.cs中的默认System.Resources.ResourceManager？

Question

我想从Resources.Designer.cs文件中覆盖System.Resources.ResourceManager以实现自定义的ResourceManager.GetString（...）方法功能。这可能吗？

我相信你在这里问两个单独的问题。你当然可以覆盖ResourceManager.GetString。但是，您不能在自动生成的Resource.Designer.cs代码中使用该覆盖。要使用它，你必须编写你自己的Resource设计师课程。

public class MyResourceManager : System.Resources.ResourceManager 
    { 
    // override 
    public override GetString(string name) 
     { 
     // custom code 
     } 
    } 

public class MyResourceDesigner 
    { 
     // use your custom class with override 
     private static MyResourceManager resourceManager; 
     private static CultureInfo resourceCulture; 

     public static MyResourceManager ResourceManager 
     { 
      if (object.ReferenceEquals(resourceManager, null)) 
       { 
        // Resource is just the name of the .resx file 
        // be sure to include relevant namespaces 
        var temp = new MyResourceManager(
        "MyProject.Resource", 
        typeof(MyResourceDesigner).Assembly); 
        resourceManager = temp; 
       } 

      return resourceManager; 
     } 

     public static CultureInfo Culture 
     { 
     get 
     { 
      return resourceCulture; 
     } 

     set 
     { 
      resourceCulture = value; 
     } 
     } 

     // start adding strongly-typed objects 
     public static string Foo 
     { 
     get 
     { 
      // use your override 
      return ResourceManager.GetString("Foo", resourceCulture); 
     } 
     } 
    } 

Answer 2

我创建了一个CustomResourceManager，它覆盖GetString()调用像这样：

public class CustomResourceManager : ResourceManager 
{ 
    public CustomResourceManager(Type resourceSource) 
     :base(resourceSource) 
    { 
    } 

    public CustomResourceManager(string baseName, Assembly assembly) 
     : base(baseName, assembly) 
    { 
    } 

    public CustomResourceManager(string baseName, Assembly assembly, Type usingResourceSet) 
     : base(baseName, assembly, usingResourceSet) 
    { 
    } 

    public override string GetString(string name) 
    { 
     // your business logic 
    } 

    public override string GetString(string name, CultureInfo culture) 
    { 
     // your business logic 
    } 
} 

然后我在生成加入了预生成步骤，我的项目替换System.Resources.ResourceManager的创建与我CustomResourceManagerResource.Designer.cs file：

powershell -command "(gc ..\Resources\Resource.Designer.cs).Replace(\"new global::System.Resources.ResourceManager\", \"new CustomResourceManager\") | set-content ..\Resources\Resource.Designer.cs -Encoding UTF8" 

我们走吧！
