How to access memory in C#?

Question

C++ / C#

in Pascal there are arrays for direct memory access Mem, MemL, and MemW
is there such a thing in C#? if so, how?

Answer 1

C# has an excellent unsafe that allows you to do basic operations with memory, such as malloc, memcpy, etc. - this is all implemented through P / Invoke - calling Managed by the Unmanaged functions code (for example, HeapAlloc-HeapFree from kernel32, for working with memory, and any other unmanaged disgrace in the context of a managed assembly)
Here are a couple of links on the topic
