我可以将IntPtr传递给方法吗？ [英] Can I pass an IntPtr to a method ?

问题描述

我一直在为较低级别的WinAPI访问控制功能编写一些Pinvoke代码。我有一个指向与TOKEN_ACCESS_INFORMATION中的访问令牌关联的权限的指针，我正在查看权限。我有工作代码但决定将其中的一部分重构为一个泛型方法，该方法给出一个带有count属性的结构的指针，可以检索与该计数相关联的项目数组。问题是传递指针的泛型方法（第一行代码）中的以下代码不会返回一致的结果。从获得指针的方法中，它是预期的。



uint uiPrivilegeCount =（uint）Marshal.PtrToStructure（privilegePointer，typeof（uint） ））;



非常感谢

Hi,

I have been writing some Pinvoke code for lower level WinAPI Access Control functions. I have a pointer to Privileges associated with my access token from the TOKEN_ACCESS_INFORMATION and I am looking at the privileges. I have working code but decided to refactor part of it to a generic method that given a pointer to a structure with a count property could retrieve the array of items associated with the count. The problem is that the following code inside the generic method ( first line of code ) that is passed the pointer does not return a consistent result. From within the method that obtained the pointer it is as expected.

uint uiPrivilegeCount = (uint)Marshal.PtrToStructure(privilegePointer, typeof(uint));

Many thanks

Tony
