Answer 1

Request.Insureds没有设置程序（甚至没有私有设置程序），因此AutoMapper无法执行任何操作。 通过添加一个私有的setter可以轻松地对其进行修复（因为随后可以通过反射对其进行设置）。

    public virtual List<Insured> Insureds {
        get {
            return this._insureds;
        }
        set {
            this._insureds = value;
        }
    }

当然，这适用于请求对象上的所有集合，没有任何类型的设置器，它们将不会被映射。
