unsafe code

If the structure is managed it must be "fixed" struct Blah {....}; fixed (blah *pBlah = myBlah) { // use pBlah here... }

"How should I write it so that I can declare pointer variables of the above structure" I attempted to write a .Net struct equivalent of the posted C structure. No problem there. But when you try to declare a pointer to an instance of the structure, even in an unsafe context, VS will issue an error. I'm not sure how to write a managed structure, then write a pointer to an instance of such.

firstly, you could use a structure for the same in C#. secondly, for unsafe code, something like public unsafe struct Node { public int Value; public Node* Left; public Node* Right; } also, you could precede your statement/method with 'unsafe' keyword. You could refer the .NET documentation which has good info( a tutorial) of using unsafe Irfan
