In C#, there are several commonly used dependency injection methods:<\/p>\n

    \n
  1. Constructor Injection: Passing dependency objects in the class’s constructor.<\/li>\n<\/ol>\n
    public<\/span> class<\/span> MyClass<\/span>\r\n{\r\n    private<\/span> readonly<\/span> IDependency _dependency;\r\n\r\n    public<\/span> MyClass<\/span>(IDependency dependency<\/span>)<\/span>\r\n    {\r\n        _dependency = dependency;\r\n    }\r\n\r\n    \/\/ ...<\/span>\r\n}\r\n<\/code><\/pre>\n
      \n
    1. Property injection: Injecting dependent objects through properties.<\/li>\n<\/ol>\n
      public<\/span> class<\/span> MyClass<\/span>\r\n{\r\n    public<\/span> IDependency Dependency { get<\/span>; set<\/span>; }\r\n\r\n    \/\/ ...<\/span>\r\n}\r\n<\/code><\/pre>\n
        \n
      1. Method Injection: Injecting dependency objects through methods.<\/li>\n<\/ol>\n
        public<\/span> class<\/span> MyClass<\/span>\r\n{\r\n    public<\/span> void<\/span> SetDependency<\/span>(IDependency dependency<\/span>)<\/span>\r\n    {\r\n        \/\/ ...<\/span>\r\n    }\r\n\r\n    \/\/ ...<\/span>\r\n}\r\n<\/code><\/pre>\n
          \n
        1. Interface injection: Injecting dependency objects by implementing specific interfaces.<\/li>\n<\/ol>\n
          public<\/span> class<\/span> MyClass<\/span> : IDependencyInjection<\/span>\r\n{\r\n    public<\/span> void<\/span> SetDependency<\/span>(IDependency dependency<\/span>)<\/span>\r\n    {\r\n        \/\/ ...<\/span>\r\n    }\r\n\r\n    \/\/ ...<\/span>\r\n}\r\n<\/code><\/pre>\n
            \n
          1. Service Locator: Resolves dependency objects through a centralized container.<\/li>\n<\/ol>\n
            public<\/span> class<\/span> MyClass<\/span>\r\n{\r\n    private<\/span> readonly<\/span> IDependency _dependency;\r\n\r\n    public<\/span> MyClass<\/span>()<\/span>\r\n    {\r\n        _dependency = ServiceLocator.Resolve<IDependency>();\r\n    }\r\n\r\n    \/\/ ...<\/span>\r\n}\r\n<\/code><\/pre>\n
            Note: The above are just some common ways of dependency injection, in actual applications, different methods can be combined to meet specific needs. Additionally, third-party dependency injection containers (such as Autofac, Unity, Ninject, etc.) can also be used to simplify the dependency injection process.<\/p>\n","protected":false},"excerpt":{"rendered":"
