allocating “unmanaged” memory in c#

Question

I\'m writting a program in c# that uses a C++ library, and for some reason I need to allocate an unmanaged buffer to pass it to the lib. Is there a way to do this in c# ? Ba

Answer 1

This is how we need to assign and free unmanaged memory by using specific number of bytes.

// Demonstrate how to call GlobalAlloc and 
// GlobalFree using the Marshal class.
IntPtr hglobal = Marshal.AllocHGlobal(100);
Marshal.FreeHGlobal(hglobal)
