Although Win32 still allows the DLL function to be accessed by ordinal, Microsoft has declared that it will not be supported in the future, a change that reflects how the system library is accessed. Also note: The current Delphi Windows unit has replaced the 16-bit Delphi Winprocs and wintypes units.callback functionThe objet Pascal support pr

in the heap. NET will perform garbage collection on a regular basis. The garbage collector recursively checks all object references in the application, and when it finds that the memory used by objects that are no longer valid is not accessible from the program, the memory can be reclaimed (except for fixed-keyword objects pinned in memory).　　But the value type allocates memory on the stack, and the reference type allocates memory on the managed heap, but it is a general statement.

What is the difference between "= =" and Equals method?For:The = = operator is specifically used to compare the values of two variables for equality, that is, to compare the memory stored in the variables corresponding to theto compare two basic types of data or two reference variables for equality, you can only use = = to manipulatecharacters. if the data that a variable points to is an object type, then it involves two blocks of memory, and the object itself occupies amemory (heap memory),

The = = operator is specifically used to compare the values of two variables, that is, whether the value stored in the memory used to compare the variables is the same, to compare two basic types of data or two reference variables equal, only with the = = operator.
