DIAttribute

Replace service registration and acquisition with attributes to simplify code writing.
用特性替代服务注册和获取，简化代码写法。

• [DIRegister]
  Used to initialise the registration service. 用于初始化注册服务。
• [DIInject]
  Used in place of the injection write method to obtain services directly. 用于代替注入写法直接获取服务。

English Description

1. [DIRegister]

native writing style

• registering for a service list:

var services = new ServiceCollection();
services.AddSingleton<TestService1>();
services.AddSingleton<ITestService2,TestService2>();
//...
var provider = services.BuildServiceProvider();

• services:

class TestService1
{
  //...
}
class TestService2
{
  //...
}
interface ITestService2 {}

current writing

• registering for a service list:

var services = new ServiceCollection();
services.RegisterCurrentAssembly(); // just add this, or services.RegisterAssembly(assmbly);
var provider = services.BuildServiceProvider();

• services:

[DIRegister] //add attribute if need register
class TestService1
{
  //...
}
[DIRegister(typeof(ITestService2))] // if use interface
class TestService2
{
  //...
}
interface ITestService2 {}

2.[DIInject]

native writing style

class TestService1
{
    ITestService2 _service2 { get; set; }

    public TestService1(ITestService2 service2 /*,TestService3 service3...*/)
    {
        _service2 = service2;
        //_service3 = service3;

        _service2.Method();
    }
}

current writing

• registering for a service list:

var services = new ServiceCollection();
//...
var provider = services.BuildServiceProvider().ForDIInject(this); //add method

• class property: You can get the service value even if the current class is not involved in the injection

class TestService1 : ServiceSetter // Inheriting this class automatically injects property values
{
    [DIInject] //add attribute if need inject
    ITestService2 _service2 { get; set; }

    public TestService1()
    {
        _service2.Method(); // can get service in constructor
    }
}

If you don't want to inherit from this base class, you can also call the property injection method manually:

class TestService1
{
    [DIInject] //add attribute if need inject
    ITestService2 _service2 { get; set; }

    public TestService1()
    {
        ServiceSetter.InjectServices(this);// manually call without inherit class
        _service2.Method(); // get service after InjectServices
    }
}

中文介绍

1.[DIRegister]

原生写法

• 初始化注册服务到集合：

var services = new ServiceCollection();
services.AddSingleton<TestService1>();
services.AddSingleton<ITestService2>();
//...
var provider = services.BuildServiceProvider();

• service服务示例：

class TestService1
{
  //...
}
class TestService2
{
  //...
}
interface ITestService2 {}

现在写法

• 初始化注册服务到集合：

var services = new ServiceCollection();
services.RegisterCurrentAssembly(); // 只要添加这行, 或者指定 services.RegisterAssembly(assmbly);
var provider = services.BuildServiceProvider();

• service服务示例：

[DIRegister] // 如果要注册的服务就添加特性
class TestService1
{
  //...
}
[DIRegister(typeof(ITestService2))] // 如果有接口则指定
class TestService2
{
  //...
}
interface ITestService2 {}

2.[DIInject]

原生写法

class TestService1
{
    ITestService2 _service2 { get; set; }

    public TestService1(ITestService2 service2 /*,TestService3 service3...*/)
    {
        _service2 = service2;
        //_service3 = service3;

        _service2.Method();
    }
}

现在写法

• 初始化注册服务到集合：

var services = new ServiceCollection();
//...
var provider = services.BuildServiceProvider().ForDIInject(this); //补充调用方法用于后续注入获取

• 类写法: 即使当前类不参与注入也可以获取到服务值

class TestService1 : ServiceSetter //继承这个类会自动给有特性的属性赋值
{
    [DIInject] //如果需要注入添加这个特性
    ITestService2 _service2 { get; set; }

    public TestService1()
    {
        _service2.Method();//服务可以在构造函数中获取到
    }
}

如果不想要继承这个基类，也可以手动调用属性注入方法：

class TestService1
{
    [DIInject] //如果需要注入添加这个特性
    ITestService2 _service2 { get; set; }

    public TestService1()
    {
        ServiceSetter.InjectServices(this);// 手动调用注入属性服务
        _service2.Method(); //服务在注入后可以获取到
    }
}
