我给出了以下代码示例：

public static class A
{
    private static B _b;

    public static B GetB
    {
        get
        {
            if(_b == null)
            {
                _b = B.load();
            }
            return _b;
        }

    }

    public static void Save()
    {
        if(_b == null)
        {
            _b = B.load();
        }
        _b.Save()
    }
}

public class B
{
    public string Value{ get; set;}

    public void Save()
    {
        //value is being save to somewhere
    }

    public static B load()
    {
        B b = new B();

        // .....
        //b.Value is loaded …
