PInvoke problema (C#) !

[Nematjon]

u menya est struktura v C app .
typedef struct _Node_Ex
{
BOOL bFolder;
BOOL bHidden;

wchar_t wszName[256];
wchar_t wszFullPath[2048];

SYSTEMTIME stDateCreated;
SYSTEMTIME stDateModified;

int nCountOfChilds;

DWORD64 dwFileSize;
HTREEITEM hItem;


} Node_Ex;

i funksiya :
extern "C" __declspec(dllexport) Node_Ex GetNode_Ex(int n);
-----------------------------------

C# code :

[StructLayout(LayoutKind.Sequential,CharSet=CharSet .Unicode,Pack=1)]
public struct Node_Ex
{
public bool bFolder;
public bool bHidden;

[MarshalAsAttribute(UnmanagedType.LPWStr, SizeConst = 256)]
public string wszName;

[MarshalAsAttribute(UnmanagedType.LPWStr, SizeConst = 2048)]
public string wszFullPath;

public SYSTEMTIME stDateCreated;
public SYSTEMTIME stDateModified;

public int nCountOfChilds;

public int dwFileSize;
public HTREEITEM hItem; //IntPtr

};

[DllImport(DLLNAME)]
public static extern Node_Ex GetNode_Ex(int n);

kagda ya ispolzuyu etot funksiya , u menya oshibka vot tak

Method's type signature is not PInvoke compatible .

Kak reshit etogo problema ?
