I cannot say I have a strong C background so I hear Handle very often these days. I know what a Pointer is (which stores address of the memory location like reference) but I am not really sure what Handle is and what the differences are between these two. And a sample code in C# would be great if you can provide one.By the way I googled this terms however many people gave different explanations so I think I get the best one from SO.EDIT:A quick heads-up for the other visitors: A handle is like a reference which points a resource. It can point at a memory address like a Pointer but Handle is more general term so it is more like a pseudo-pointer.

A file is a good example for this. A file can have an ID which OS can understand and use to find the file. So Handle can hold this ID (which may or may not be a Memory Address) and when we pass this Handle in, OS can find the file easily.Please refer to answers below for more detailed information.Edit:All the answers under this question are awesome and very explanatory. I am having a hard time to select one of them to mark it as answer. Sorry, no C# example, but:Pointer is a memory address, which in this case points to where the object is stored in memory.

This is a low level concept that C inherited from C.Regarding the handle:The term handle is used to mean any technique that lets you get to another object — a generalized pseudo-pointer. The term is (intentionally) ambiguous and vague.One more important term that is closely related is an object reference, which is an 'alias' for the object.You may get a rather clear and concise answers on. After thinking your answer. It made a huge sense to me right now. Handle is more general term. Could you please verify this: A Pointer must have a memory address to be called pointer.

Handle is more general term and it doesn't have to hold memory address but any integer value that kernel can understand. So a handle can store a 1234545 which is not memory address but kernel uses that number to identify a file in a table maybe. But Handle can also store memory address and can be used as Pointer too. Is that right?–May 22 '12 at 15:38.
