如何在 C# 中使用属性实现依赖注入?

将耦合(依赖)对象注入(转换)到解耦(独立)对象的过程称为依赖注入。
依赖注入的类型
DI 有四种类型 −
构造函数注入
Setter 注入
基于接口的注入
服务定位器注入
Setter 注入
Getter 和 Setter 注入通过使用默认的公共属性过程(例如 Gettter(get(){}) 和 Setter(set(){}))来注入依赖项。
示例
public interface IService{
string ServiceMethod();
}
public class ClaimService:IService{
public string ServiceMethod(){
return "ClaimService is running";
}
}
public class AdjudicationService:IService{
public string ServiceMethod(){
return "AdjudicationService is running";
}
}
public class BusinessLogicImplementation{
private IService _client;
public IService Client{
get { return _client; }
set { _client = value; }
}
public void SetterInj(){
Console.WriteLine("Getter and Setter Injection ==>
Current Service : {0}", Client.ServiceMethod());
}
}
消费
BusinessLogicImplementation ConInjBusinessLogic = new BusinessLogicImplementation(); ConInjBusinessLogic.Client = new ClaimService(); ConInjBusinessLogic.SetterInj();
