C# 改写VC代码

[wolf_Knight]

请哪位大侠帮忙用C#改写一下VC代码（环境Wince)

unsigned char* GetStorageID(LPCTSTR szDisk)
{
	BYTE *SerialNo ;
	HANDLE hDisk = CreateFile(szDisk ,GENERIC_READ,FILE_SHARE_READ | FILE_SHARE_WRITE , NULL , OPEN_EXISTING , 0 , NULL);
	PSTORAGE_IDENTIFICATION pStoreInfo = (PSTORAGE_IDENTIFICATION) new BYTE[3000];
	DWORD dwBytesRet;
	if(!DeviceIoControl(hDisk , IOCTL_DISK_GET_STORAGEID, NULL , 0 , pStoreInfo , 3000 , &dwBytesRet , NULL))
	{
		DWORD err = GetLastError();
		delete [] pStoreInfo;
		CloseHandle(hDisk);
		return FALSE;
		}
	else
	{
		SerialNo = (((BYTE *)pStoreInfo) + pStoreInfo->dwManufactureIDOffset); 

	}
	CloseHandle(hDisk);
	return SerialNo;
}

#define IOCTL_DISK_GET_STORAGEID CTL_CODE(FILE_DEVICE_DISK, 0x709,METHOD_BUFFERED,FILE_ANY_ACCESS)
typedef struct _STORAGE_IDENTIFICATION
{
	DWORD dwSize;
	DWORD dwFlags;
	DWORD dwManufactureIDOffset;
	DWORD dwSerialNumOffset;
} STORAGE_IDENTIFICATION, *PSTORAGE_IDENTIFICATION;

什么意思？没有看明白吗？

[mjp1234airen4385]

太郁闷了。
有要引入多个windowsapi，还要定义结构和常量，
不愿意整

哪位兄弟帮帮忙看看

[shangwei97]

没调试这段代码，看大概意思，你是从wince的文件中读取一个类似SN号的东西吗
你既然知道是要得到什么东西，可以直接用C#去实现这段代码，何必去改写。
改写的时间，你都可以直接把上面代码封装成动态库去调用了

using System;

public class GlobalMembers
{
	public static byte GetStorageID(string szDisk)
	{
		byte SerialNo = 0;
		IntPtr hDisk = CreateFile(szDisk,GENERIC_READ,FILE_SHARE_READ | FILE_SHARE_WRITE, null, OPEN_EXISTING, 0, null);
		_STORAGE_IDENTIFICATION[] pStoreInfo = (_STORAGE_IDENTIFICATION)(new byte[3000]);
		uint dwBytesRet = 0;
		if (! (DeviceIoControl(hDisk, IOCTL_DISK_GET_STORAGEID, null, 0, pStoreInfo, 3000, dwBytesRet, null)))
		{
			uint err = GetLastError();
			pStoreInfo = null;
			CloseHandle(hDisk);
			return 0;
		}
		else
		{
			SerialNo = ((Convert.ToByte(pStoreInfo)) + pStoreInfo.dwManufactureIDOffset);

		}
		CloseHandle(hDisk);
		return SerialNo;
	}
}

#define IOCTL_DISK_GET_STORAGEID
public class _STORAGE_IDENTIFICATION
{
	public uint dwSize;
	public uint dwFlags;
	public uint dwManufactureIDOffset;
	public uint dwSerialNumOffset;
}

太多不明确的地方，写一点给你，自己完成吧

        [DllImport("kernel32.dll ", EntryPoint = "CreateFile ")]
        public static extern int CreateFile(
        string lpFileName,
        int dwDesiredAccess,
        int dwShareMode,
        IntPtr lpSecurityAttributes,
        int dwCreationDisposition,
        int dwFlagsAndAttributes,
        int hTemplateFile
        );

        uint GENERIC_READ = (uint)0x80000000;
        uint GENERIC_WRITE = 0x40000000;
        int FILE_SHARE_READ = 0x00000001;
        int FILE_SHARE_WRITE = 0x00000002;
        int OPEN_EXISTING = 3;
//CreateFile可以按下面用
SafeHandle hDisk = CreateFile(szDisk, GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE, null, OPEN_EXISTING, 0, null);

兄弟，谢谢，API函数，我都知道。

[wolf_Knight]

这个 GetStorageID 函数，是用来获取SD卡序列号的，我是不知道函数下面几个地方不知道怎么改写

PSTORAGE_IDENTIFICATION pStoreInfo = (PSTORAGE_IDENTIFICATION) new BYTE[3000];
    DWORD dwBytesRet;
    if(!DeviceIoControl(hDisk , IOCTL_DISK_GET_STORAGEID, NULL , 0 , pStoreInfo , 3000 , &dwBytesRet , NULL))
    {
        DWORD err = GetLastError();
        delete [] pStoreInfo;
        CloseHandle(hDisk);
        return FALSE;
        }
    else
    {
        SerialNo = (((BYTE *)pStoreInfo) + pStoreInfo->dwManufactureIDOffset); 

    }
    CloseHandle(hDisk);
    return SerialNo;

另外这个API我是这样定义的，也不知道对不

[DllImport("coredll.dll", EntryPoint = "DeviceIoControl", SetLastError = true)]
        internal static extern int DeviceIoControlCE(
            int hDevice,
            UInt64 dwIoControlCode,
            byte[] lpInBuffer,
            int nInBufferSize,
            byte[] lpOutBuffer,
            int nOutBufferSize,
            ref int lpBytesReturned,
            IntPtr lpOverlapped);
