C#中的浅复制(shallow copy),深复制(deep copy) 及 ICloneable 当复制一个单纯的值类型源的时候,问题就比较简单,直接复制源内容,在栈上重新生成一份拷贝即可。无所谓浅复制,深复制。 但是当复制源是一个引用类型的对象,比如 string 对象,那么就有两种复制法了,一种是直接生成另一个引用,然后指向同一块堆内存。
Deep Copy Shallow Copy Deep Copy This a method of copying contents from one object to another object. In this copying technique, the changes made in the copied object are not reflected in the original object. This shows that the new object copy created and the original object do not share ...
shallow copy和deep copy的区别 问题:shallow copy和deep copy的区别回答: 浅拷贝的意思是每个数组元素包含了与原数组元素相同的引用。 deep copy是则是创建一个新的实例,返回一个不同的对象。©2022 Baidu |由 百度智能云 提供计算服务 | 使用百度前必读 | 文库协议 | 网站地图 | 百度营销 ...
Python的拷贝有一个专门的模块,叫做copy。 浅拷贝 importcopy;>>> l=[1,2,3,[4,5],6]>>> c=copy.copy(l)>>>id(l)39195912L >>>id(c)39238600L 从内存引用里清晰的显示,至少内存地址不一样了,对l进行内容变更应该不会影响到c。 >>> l.append('z')>>>l [1, 2, 3, [4, 5], 6,'z...

Rather, in C#, when you say: MyObject X = new MyObject(); MyObject Y = new MyObject(); X = Y; //what does this '=' mean? Is "X=Y" a shallow copy? I think it is. So is X=Y above equivalent to using ICloneable to produce a shallow copy clone ("return (this.Memberwis...
Shallow copy = Bitwise copy. Deep copy = Memberwise copy. Long story short, a shallow copy only copies the binary, in memory, print of a class. A deep copy "dives into" the members, and copy their logical data. Example: If you've got a class with one member, which is a pointer...
