Hai, in my application i am using Pinvoke method from c# wpf to C++ dll.i created the same structure in c# which was in c++ dll and i am calling the method with ref of my struct from c# and then there is no problem.for some dynamic purpose i am using callback delegate method at that time i cant able to pass the ref of struct so i sent the Intptr to get the address from c++ dll,now i am getting the address of mystruct but now i need to get the values from the pointer value is it possible to do like these or any other method please suggest me.

What I have tried:

i have tried,i pass the ref struct from c# to c++ without callback,facing problemm when i use call back method.

C# uses garbage collection to compact the objects in the memory from time to time, so the address of objects may change. The address you saved might not be valid or pointing to the same object. Intptr pins the object during the pinvoke. After the intptr variable goes out of scope, the object is not pinned and may be moved during a GC. So instead of saving the address, you should save the index/position of that object in an array or List.
