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

我想从Resources.Designer.cs文件覆盖System.Resources.ResourceManager以实现自定义ResourceManager.GetString（…）方法function。 这可能吗？

Answer 1

我相信你在这里问两个不同的问题。 您当然可以覆盖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，您必须编写自己的Resource设计器类。

 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来覆盖GetString()调用，如下所示：

 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 } } 

然后我在我的项目中添加了一个预构建步骤，用生成的Resource.Designer.cs文件中的CustomResourceManager替换System.Resources.ResourceManager的创建：

 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！
