在Linq中获取没有空属性的对象

Question

我想要pa但是空MG道具。

Parent pa = new Parent()
               {
                   MC = new Child[]
                            {
                                new Child() {M1 = 1},
                                new Child() {M1 = 2},
                                new Child() {M1 = 3},
                            },
                   MG = new GrandChild[]
                            {
                                new GrandChild() {M2 = "1"},
                                new GrandChild() {M2 = ""},
                                new GrandChild() {M2 = ""},
                                new GrandChild() {M2 = "4"},
                            },
                   MP = "just string prop",
               };

我知道这不是真的，但想要这样对待我的对象：

var vv = pa.MG.Where(_p=>_p.M2!="").Select(_k=>_k.**parent**) 

Answer 1

pa.MG = pa.MG.Where(gc => gc.M2 != "").ToArray();
