Here is a solution. It uses p/invoke, but seems to work well, 32 or 64 cpu: /// <summary> /// A utility class to determine a process parent. /// </summary> [StructLayout(LayoutKind.Sequential)] public struct ParentProcessUtilities { // These members must match PROCESS_BASIC_INFORMATION internal IntPtr Reserved1; internal IntPtr PebBaseAddress; internal IntPtr Reserved2_0; internal IntPtr Reserved2_1; internal IntPtr UniqueProcessId; … Read more
Because different languages and environments have different calling conventions, different layout conventions, different sizes of primitives (cf. char in C# and char in C), different object creation/destruction conventions, and different design guidelines. You need a way to get the stuff out of managed land an into somewhere where unmanaged land can see and understand it … Read more
The term “unmanaged resource” is usually used to describe something not directly under the control of the garbage collector. For example, if you open a connection to a database server this will use resources on the server (for maintaining the connection) and possibly other non-.net resources on the client machine, if the provider isn’t written … Read more
Managed Code Managed code is what Visual Basic .NET and C# compilers create. It runs on the CLR (Common Language Runtime), which, among other things, offers services like garbage collection, run-time type checking, and reference checking. So, think of it as, “My code is managed by the CLR.” Visual Basic and C# can only produce … Read more
This is a good article about the subject. To summarize, Managed code is not compiled to machine code but to an intermediate language which is interpreted and executed by some service on a machine and is therefore operating within a (hopefully!) secure framework which handles dangerous things like memory and threads for you. In modern … Read more
