问使用接口调用2个方法

EN

public interface IExample
{
    void DoSomething(string parameter1);
}

public class ExampleImpl : IExample
{
    private IExample actualImplementation;

    public ExampleImpl(IExample actualImplementation)
    {
        this.actualImplementation = actualImplementation;
    }

    public void DoSomething(string parameter1)
    {
        //Code to log function begin here

        this.actualImplementation.DoSomething(parameter1);

        //Code to log function end here
    }
}

IExample thisObjectLogsFunctionCalls = new ExampleImpl(new AnotherProgrammersImplementation());

thisObjectLogsFunctionCalls.DoSomething("test string");
