C#如何优雅处理引用类型的深拷贝 （九）

几年前写过一个 bug根因很土该深拷贝的地方没深拷贝副本一改原件跟着变。排查的时候老板以为动的是库里的数据其实就是一个本地对象被共享了。先把词说清楚浅拷贝值类型复制一份引用类型复制的是引用两边还指着同一个子对象。你改副本里的引用成员原件也会变。只复制对象自身的一层字段/属性里如果是值类型会复制一份值如果是引用类型复制的是引用指针新旧对象仍指向同一块堆上的子对象。深拷贝引用链上也建新对象改副本不该动到原件的嵌套数据。从根对象开始递归地为引用类型也创建新实例并把内容复制过去直到整棵「对象图」在逻辑上独立。改拷贝不应意外改动原对象里的嵌套数据。ICloneable能深但接口不保证ICloneable只有一个object Clone()文档不会替你承诺浅还是深看实现。你想做深拷贝可以全写在Clone()里就行。浅拷贝场景下改拷贝里的引用类型字段往往会影响原对象反之亦然除非你再给那个字段赋一个新实例。https://github.com/kewarh1/dcobxt/blob/main/ZkbLpJmGkE_5665094.mdhttps://github.com/jrnov/xwieaw/blob/main/ayms63ULZ3_2221155.mdhttps://github.com/insbrangotekson/hbhkxt/blob/main/jU15iWdNrL_9009938.mdhttps://github.com/justinghove/tobnjf/blob/main/lFjge4vf9d_4889504.mdhttps://github.com/kewarh1/dcobxt/blob/main/IcmdNrLpJn_1116044.mdhttps://github.com/abdys-lono/gqwznj/blob/main/FtgHyOFzTx_4554983.mdhttps://github.com/jrnov/xwieaw/blob/main/HvFtDrelVz_7887765.mdhttps://github.com/insbrangotekson/hbhkxt/blob/main/TX8Px4oImG_7899837.mdhttps://github.com/jrnov/xwieaw/blob/main/v9aTHO8c6a_4554837.mdhttps://github.com/justinghove/tobnjf/blob/main/b8iPm3biSw_6664438.mdhttps://github.com/kewarh1/dcobxt/blob/main/9QU8S5t0kE_6609837.mdhttps://github.com/abdys-lono/gqwznj/blob/main/EySwPNneOs_6776509.mdhttps://github.com/insbrangotekson/hbhkxt/blob/main/29QxXiZJnH_3332266.mdhttps://github.com/justinghove/tobnjf/blob/main/EL5cgK7EyS_6776509.mdhttps://github.com/jrnov/xwieaw/blob/main/dneOsMqKoI_2382165.mdhttps://github.com/kewarh1/dcobxt/blob/main/ZquYsWJQAe_0056054.mdhttps://github.com/abdys-lono/gqwznj/blob/main/Yps0Kymsc6_0004988.mdhttps://github.com/kewarh1/dcobxt/blob/main/0HLzJwkrb5_3443872.mdhttps://github.com/jrnov/xwieaw/blob/main/C3Gh4LszjD_6660049.mdhttps://github.com/justinghove/tobnjf/blob/main/OYP9d7b5Z3_8888226.mdhttps://github.com/insbrangotekson/hbhkxt/blob/main/ak5pJnHlFj_2221105.mdhttps://github.com/abdys-lono/gqwznj/blob/main/KbfJdH4BvP_9009933.mdhttps://github.com/insbrangotekson/hbhkxt/blob/main/X48l3dneOs_3384482.mdhttps://github.com/justinghove/tobnjf/blob/main/YztCqelVzT_8998822.mdhttps://github.com/insbrangotekson/hbhkxt/blob/main/8zjDhBf9d7_5665460.mdhttps://github.com/abdys-lono/gqwznj/blob/main/RBgghEL5Z3_4599332.mdhttps://github.com/jrnov/xwieaw/blob/main/1evzAUeVFj_9443276.mdhttps://github.com/justinghove/tobnjf/blob/main/DKY59nahRv_1092531.mdhttps://github.com/insbrangotekson/hbhkxt/blob/main/R82M3xkrb5_1221594.mdhttps://github.com/kewarh1/dcobxt/blob/main/cF3AuvTaKo_5559932.mdhttps://github.com/abdys-lono/gqwznj/blob/main/iITJXUvmW0_0000948.mdhttps://github.com/jrnov/xwieaw/blob/main/PWjh81pQAe_0122105.mdhttps://github.com/justinghove/tobnjf/blob/main/Z9NoiVcMqK_4998876.mdhttps://github.com/insbrangotekson/hbhkxt/blob/main/AhIVwqdkUy_4504438.mdhttps://github.com/kewarh1/dcobxt/blob/main/VC6Q4ryiCg_9910509.mdhttps://github.com/abdys-lono/gqwznj/blob/main/wjJ0uioY2W_1111599.mdhttps://github.com/jrnov/xwieaw/blob/main/vLCPqkXeOs_8887327.mdhttps://github.com/justinghove/tobnjf/blob/main/NH4izZkbLp_9009933.mdhttps://github.com/insbrangotekson/hbhkxt/blob/main/MQXoMTDhBf_0004337.mdhttps://github.com/kewarh1/dcobxt/blob/main/5zJxHuipZ3_5504483.mdhttps://github.com/jrnov/xwieaw/blob/main/XBzctUeVFj_3443226.mdhttps://github.com/abdys-lono/gqwznj/blob/main/1yPJdH4BvP_2221105.mdhttps://github.com/insbrangotekson/hbhkxt/blob/main/ubVnuBipZ3_0559832.mdhttps://github.com/justinghove/tobnjf/blob/main/E5JGhbOVFj_8998872.mdhttps://github.com/kewarh1/dcobxt/blob/main/MdAlStjTxR_7771054.mdhttps://github.com/jrnov/xwieaw/blob/main/v2nKN1pwgA_0943721.mdhttps://github.com/abdys-lono/gqwznj/blob/main/2cndroF6qK_6666549.mdhttps://github.com/insbrangotekson/hbhkxt/blob/main/QDr8CpdkUy_6150115.mdhttps://github.com/justinghove/tobnjf/blob/main/dUEiCgAe8c_7226600.mdhttps://github.com/kewarh1/dcobxt/blob/main/0xuIdneOsM_5615591.mdhttps://github.com/jrnov/xwieaw/blob/main/WKRhFpzqa4_7998721.mdhttps://github.com/abdys-lono/gqwznj/blob/main/xXhYmj90kE_5665094.mdhttps://github.com/insbrangotekson/hbhkxt/blob/main/NhsjTxRuOs_5555435.mdhttps://github.com/justinghove/tobnjf/blob/main/A71LWrb5Z3_5000938.mdhttps://github.com/kewarh1/dcobxt/blob/main/8Mnh1eSZJn_8809938.mdhttps://github.com/jrnov/xwieaw/blob/main/VPjMAH1VzT_2221105.mdhttps://github.com/abdys-lono/gqwznj/blob/main/CdXKRBf9d7_7887716.mdhttps://github.com/insbrangotekson/hbhkxt/blob/main/zMdAH1VzTx_6666509.mdhttps://github.com/justinghove/tobnjf/blob/main/BwwxUbLpJn_3322382.mdhttps://github.com/kewarh1/dcobxt/blob/main/dR5Mw6xhBf_1665499.mdhttps://github.com/jrnov/xwieaw/blob/main/jGqXuBjqa4_2221155.mdhttps://github.com/abdys-lono/gqwznj/blob/main/CMDuLgQuOs_3822600.mdhttps://github.com/justinghove/tobnjf/blob/main/TaLswZNUEi_2276605.mdhttps://github.com/insbrangotekson/hbhkxt/blob/main/OIcGaD18sM_3888226.mdhttps://github.com/kewarh1/dcobxt/blob/main/CghiFM64Y2_5665591.mdhttps://github.com/abdys-lono/gqwznj/blob/main/5F6JHhYImG_1159559.mdhttps://github.com/jrnov/xwieaw/blob/main/r9jtkUySwQ_9011555.mdhttps://github.com/justinghove/tobnjf/blob/main/Lw9aUHO8c6_9998844.mdhttps://github.com/insbrangotekson/hbhkxt/blob/main/vPPQy5pJmG_2211554.mdhttps://github.com/kewarh1/dcobxt/blob/main/41vFPjulVz_5776605.mdhttps://github.com/abdys-lono/gqwznj/blob/main/qqNyf6xhBf_7777615.mdhttps://github.com/jrnov/xwieaw/blob/main/cCtKBvtNrL_7726099.mdhttps://github.com/justinghove/tobnjf/blob
