In .NET memory is allocated by the CLR as and when required. If there is insufficient memory remaining on the heap to store a new object then a garbage collection automatically takes place to free up memory that is no longer required by the process. Consequently there is no need for you to manage memory yourself such as in C or (unmanaged) C++. It is possible to allocate 'unmanaged' memory yourself (for interop purposes) using methods of the System.Runtime.InteropServices.Marshal class such as AllocHGlobal(): http://msdn2.microsoft.com/en-us/library/system.runtime.interopservices.marshal.allochglobal(vs.80).aspx In 'unsafe' code you can also allocate memory on the stack using the 'stackalloc' keyword: http://msdn2.microsoft.com/en-us/library/cx9s2sy4(VS.80).aspx
