Howto Convert NOTIFYICONDATA Into NotifyIcon

Question

I'm trying to convert a struct I have defined to match the NOTIFYICONDATA in C++(I think I have it right) and I am trying to convert this into a NotifyIcon object in C#. First I am receiving the SHELLTRAYDATA that an application sends with Shell_NotifyIcon. My SHELLTRAYDATA was defined as such:

C++

public struct NID_XX
{
    public UInt32 cbSize;
    public IntPtr hWnd;
    public uint uID;
    public uint uFlags;
    public uint uCallbackMessage;
    public IntPtr hIcon;
}
public struct PSHELLTRAYDATA
{
    public UInt32 dwUnknown;
    public UInt32 dwMessage;
    public NID_XX nid;
}

Now from my understanding NID_XX is equivalent to NOTIFYICONDATA but I can't seem to find out how to convert this into a NotifyIcon. I am working mostly in C# but I do have a C++ DLL I am using to receive this data, so if something else needs to be done in C++ that won't be an issue.

use DllImport attribute to call the Shell_NotifyIcon() API, and marshal the patameter to CLR type

check this link Platform Invoke Data Types[^]

C#

// BOOL Shell_NotifyIcon(
//  __in  DWORD dwMessage,
//  __in  PNOTIFYICONDATA lpdata
//);
[DllImport("Shell32.dll", CharSet = CharSet.Unicode)]
public static extern Int32 Shell_NotifyIcon(UInt32 message, ref NotifyIconData iconData);
