对于某些情况,使用StructureMap将不同的对象注入构造函数

public interface IExample
{
    void DoSomething();
}

public class Example1 : IExample
{
    public void DoSomething()
    {
        Console.WriteLine("Example 1");
    }
}

public class Example2 : IExample
{
    public void DoSomething()
    {
        Console.WriteLine("Example 2");
    }
}

public class MyClass
{
    private readonly IExample _example;

    public MyClass(IExample example)
    {
        _example = example;
    }

    public void DoSomething()
    {
        _example.DoSomething();
    }
}

public class Program
{
    public static void Main(string[] args)
    {
        var container = new Container(cfg =>
        {
            cfg.For<IExample>().Use<Example1>();
        });

        var myClass = container.GetInstance<MyClass>();
        myClass.DoSomething(); // 输出 "Example 1"
    }
}
