你可以说是 reference type vs value type 的区别。但其实精确一点, Python 本身是只有 reference type,区别只是这个 reference type 是可变还是不可变的。 我感觉 SO 上面的一些回答也很有启发,比如: This is a long-winded way to say that when people call integers "value types" in Python they are prob...
Value typesand reference types are the two main categories of C# types. A variable of a value type contains an instance of the type. This differs from a variable of a reference type, which contains a reference to an instance of the type. By default, on assignment, passing an argument to...
As per Microsoft, "Variables of reference types store references to their data (objects), while variables of value types directly contain their data. With reference types, two variables can reference the same object; therefore, operations on one variable can affect the object referenced by the oth...
One area likely to cause confusion for those coming from a Java or VB6 background is the distinction between value types and reference types in C#.In particular, C# provides two types—class and struct, which are almost the same except that one is a reference type while the other is a va...
Value Type VS Reference Type 找了个比较清晰的图片来比较.NET中的两个基本类型在内存分配上的区别。 由此可以看出: 1. 值类型是分配在堆栈上的,而引用类型是分配到托管堆上的。 2. 引用类型有方法表,所以通过方法表可以实现继承,多态等,而值类型则不能。
(.NET Framework/Core & Mono) ,those implementation details are super important,especially in high-performance programming(fe. taking advantage of stack/registers with the help of struct/ref struct). My clue is, it is much better tounderstand the rationalebehind value types vs reference types ...

Value vs. reference types This module focuses on the two kinds of types in C#: reference types and value types. Variables of reference types store references to their data (objects), that is they point to data values stored somewhere else. In comparison, variables of value types directly cont...
Value types are bytes of data that contain values in memory, reference types are addresses to bytes of data in memory. Reference types are pointers (C/C++) to an address, and variables/fields store data. @isoiso1371 man code monkey is truly a code silverback gorilla @thedeltastrat This is...
