目的：C#调API创建窗口

注册窗口类：
ATOM RegisterClassEx（CONST WNDCLASSEX *Ipwcx）（这里参数怎么写？）
创建窗口：
HWND CreateWindowEx(
DWORD dwExStyle，
LPCTSTR IpClassName，
LPCTSTR lpWindowName，
DWORD dwStyle，
int x，
int y,
int nWidth，
int nHeight，
HWND hWndParent，
HMENUhMenu，
HANDLE hlnstance，
LPVOID lpParam）

贴下我现在的代码，求解答



[DllImport("User32.dll", EntryPoint = "CreateWindowEx")]

        public static extern IntPtr CreateWindowEx(

            ExWindowStyle dwExStyle,

            string lpClassName,

            string lpWindowName,

            WindowStyle dwStyle,

            int x,

            int y,

            uint nWidth,

            uint nherght,

            IntPtr hWndParent,

            IntPtr hMenu,

            IntPtr hlnstance,

            int lpParam);

[DllImport("user32.dll", EntryPoint = "RegisterClassEx")]

        public static extern int RegisterClassEx(

                  [In] ref WNDCLASSEX Ipwcx

                 );



WNDCLASSEX aWNDCLASSEX = new WNDCLASSEX();

            aWNDCLASSEX.cbSize = (int)Marshal.SizeOf(aWNDCLASSEX);

            aWNDCLASSEX.style = 0;

            aWNDCLASSEX.lpfnWndProc = new IntPtr();

            aWNDCLASSEX.cbClsExtra = 0;

            aWNDCLASSEX.cbWndExtra = 0;

            aWNDCLASSEX.hIcon = new IntPtr();

            aWNDCLASSEX.hCursor = new IntPtr();

            aWNDCLASSEX.hbrBackground = new IntPtr();

            aWNDCLASSEX.lpszMenuName = null;

            aWNDCLASSEX.lpszClassName = "WinClass";

            aWNDCLASSEX.hIconSm = new IntPtr();

            RegisterClassEx(ref aWNDCLASSEX);



            int lpParam = 0;

            IntPtr hWndParent = new IntPtr();

            IntPtr hMenu = new IntPtr();

            IntPtr i = CreateWindowEx (ExWindowStyle.WS_EX_CLIENTEDGE, "lpClassName", "lpWindowName", WindowStyle.WS_BORDER, 100, 100, 100, 100, hWndParent, hMenu, aWNDCLASSEX.hInstance, lpParam);

            ShowWindow(i, 1);

C# code

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]
public struct WNDCLASSEX
{
[MarshalAs(UnmanagedType.U4)]
public int cbSize;……

问下
RegisterClassEx注册窗口类
CreateWindowEx创建窗体
那 RegisterClassEx 怎么为将要创建的窗体注册，我实在有点晕
能不能帮忙写个例子啊，就是创建个窗体出来就行

你可以翻看.net 2.0 framework的源代码，看看form.show是如何调用api的。
