Solution 1

C# does not have, or use malloc in any way, shape or form.

.NET applications are Managed: which means they have their own memory management built in (via the new keyword) and which is tied into the Garbage Collection system. They do not use malloc, or free as the memory is handled by the system for you.

Griff is right (mostly) :)

99.999% of the time, working with objects in .NET you will only use the "new" operator, which works with managed memory.

However, there are rare circumstances that you need to allocate unmanaged memory, just like you would with malloc. .NET does provide a method for doing this with the Marshal class, specifically the Marshal.AllocHGlobal[^] and Marshal.FreeHGlobal[^].

Its also worth noting that you don't really want to use the above unless you are working with some specialized unmanaged code. Allocating memory and forgetting to free it creates memory leaks.
