我写了一个ppc程序，用来给PDA安装CmpactFramwork2.0,代码如下：

public class ShellExecute

    {

        public static void Start(string fileName, string parameters)

        {

            int nSize;

            SHELLEXECUTEEX see;

            IntPtr pFile;

            IntPtr pParams;



            see = new SHELLEXECUTEEX();



            nSize = fileName.Length * 2 + 2;

            pFile = localAlloc(MemoryAllocFlags.LPtr, nSize);

            Marshal.Copy(Encoding.Unicode.GetBytes(fileName), 0, pFile, nSize - 2);



            nSize = parameters.Length * 2 + 2;

            pParams = localAlloc(MemoryAllocFlags.LPtr, nSize);

            Marshal.Copy(Encoding.Unicode.GetBytes(parameters), 0, pParams, nSize - 2);



            see.lpFile = pFile;

            see.lpParameters = pParams;



            ShellExecuteEx(see);



            LocalFree(pFile);

            LocalFree(pParams);

            //return   see.hProcess;   

        }



        public static void Start(string fileName)

        {

            Start(fileName, "");

        }



        private static IntPtr localAlloc(MemoryAllocFlags uFlags, int uBytes)

        {

            const int GMEM_FIXED = 0x0000;

            const int LMEM_ZEROINIT = 0x0040;

            const int LPTR = (GMEM_FIXED | LMEM_ZEROINIT);



            IntPtr ptr = LocalAlloc(LPTR, (uint)uBytes);

            if (ptr == IntPtr.Zero)

                throw new Exception("Out   of   memory!");

            return ptr;

        }



        private enum MemoryAllocFlags : int

        {

            Fixed = 0x00,

            ZeroInit = 0x40,

            LPtr = ZeroInit | Fixed

        }



        #region   APIs

        [DllImport("coredll.dll")]

        private static extern IntPtr LocalAlloc(uint uFlags, uint Bytes);



        [DllImport("coredll")]

        private static extern IntPtr LocalFree(IntPtr hMem);



        [DllImport("coredll")]

        private extern static int ShellExecuteEx(SHELLEXECUTEEX ex);



        private class SHELLEXECUTEEX

        {

            public UInt32 cbSize = 60;

            public UInt32 fMask = 0;

            public IntPtr hwnd = IntPtr.Zero;

        }

        #endregion
