您可以在Windsor容器中注册一个类型的现有实例吗？

Question

在温莎国际奥委会容器中，是否可以注册一个我已经拥有实例的类型，而不是让容器创建它？

Answer 1

容器的Kernel属性上有一个AddComponentInstance方法。

从单元测试：

[Test] 
    public void AddComponentInstance() 
    { 
     CustomerImpl customer = new CustomerImpl(); 

     kernel.AddComponentInstance("key", typeof(ICustomer), customer); 
     Assert.IsTrue(kernel.HasComponent("key")); 

     CustomerImpl customer2 = kernel["key"] as CustomerImpl; 
     Assert.AreSame(customer, customer2); 

     customer2 = kernel[typeof(ICustomer)] as CustomerImpl; 
     Assert.AreSame(customer, customer2); 
    } 

    [Test] 
    public void AddComponentInstance_ByService() 
    { 
     CustomerImpl customer = new CustomerImpl(); 

     kernel.AddComponentInstance <ICustomer>(customer); 
     Assert.AreSame(kernel[typeof(ICustomer)],customer); 
    } 

    [Test] 
    public void AddComponentInstance2() 
    { 
     CustomerImpl customer = new CustomerImpl(); 

     kernel.AddComponentInstance("key", customer); 
     Assert.IsTrue(kernel.HasComponent("key")); 

     CustomerImpl customer2 = kernel["key"] as CustomerImpl; 
     Assert.AreSame(customer, customer2); 

     customer2 = kernel[typeof(CustomerImpl)] as CustomerImpl; 
     Assert.AreSame(customer, customer2); 
    }
