c# - 型の既存のインスタンスを Windsor Container に登録できますか?

Question

Windsor IOC コンテナーでは、コンテナーで作成する代わりに、既にインスタンスを取得している型を登録することはできますか?

Answer 1

Container の Kernel プロパティに AddComponentInstance メソッドがあります。

単体テストから:

[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);
}
