It's "just" creating a pinned local variable in il and everything this variable is pointing to is considered pinned by the gc. you can read more about this here . now i wonder: is it possible to pin a field of a class or struct so that the object it points to is assumed as pinned by the gc without using gchandle or so.

Instead of using new operator, we are able to allocate arrays with the help of two methods: 1. 2. gc.allocatearray<t>( arraylength, pinned: true); gc.allocateuninitializedarray<t>( arraylength, pinned: true); as we see, the new allocation api allows us specify that we want to have this object pinned. and this fact allows to allocate it directly. The best case scenario is when you pin something for a short period of time that the gc doesn't notice. if there isn't a gc, objects aren't moved around. therefore whether something is pinned or not has no effect. and, of course, maintaining control can be tough at times. alternatively, you can pin objects that aren't going to move. The easiest way to do this is to specify managed type directly on the p invoke method: directly using "mytype" as parameter type. [dllimport("nativelib") ] private static extern void do something(mytype mytype); then call this method: gchandle handle = gchandle.alloc(objecttobepinned, gchandletype.pinned);.
