获取U盘序列号 是固定的那个 不要逻辑的

[hai291928193]

如题 谢谢了 别从网上找了 都是逻辑的

人呢 。。。。。Eleven大大在哪？

奉劝楼主不要把有限的生命浪费在无限的加密解密死循环中！

固定的，应该是硬件相关的，估计要USB相关驱动等才能获取到 或者DeviceIoControl试试，看能不能拿到

赵大大 你想多了 我只是想看看而已 什么加密解密对我来说太遥远

用IOCTL_STORAGE_QUERY_PROPERTY 可以获取硬盘的序列号, U盘的也行, 但是并不是所有的U盘都有序列号, 很多都没有, 以下代码参考, Info.szSerialNumber 就是序列号

BOOL	NUsb::GetDiskProp(HANDLE hDisk, _LogDiskInfo &Info)
{
	STORAGE_PROPERTY_QUERY		PropQuery;
	DWORD						dwSize, dwRead;
	BOOL						bRetVal;
	int							nError;

	memset(&PropQuery, 0, sizeof(PropQuery));
	PropQuery.PropertyId = StorageDeviceProperty;
	PropQuery.QueryType = PropertyStandardQuery;
	dwSize = sizeof(Info.DevDescrip) + sizeof(Info.bzDevDescripEx);
	bRetVal = ::DeviceIoControl(hDisk, IOCTL_STORAGE_QUERY_PROPERTY, &PropQuery, sizeof(PropQuery),	&Info.DevDescrip, dwSize, &dwRead, NULL);
	if(bRetVal == FALSE)
	{
		nError = GetLastError();
		if(nError != ERROR_INVALID_FUNCTION)
            assert(0);
	}
	if(Info.DevDescrip.VendorIdOffset)
		strcpy(Info.szVendorId, (CHAR *)&Info.DevDescrip + Info.DevDescrip.VendorIdOffset);
	if(Info.DevDescrip.ProductIdOffset)
		strcpy(Info.szProductId, (CHAR *)&Info.DevDescrip + Info.DevDescrip.ProductIdOffset);
	if(Info.DevDescrip.ProductRevisionOffset)
		strcpy(Info.szProductRevision, (CHAR *)&Info.DevDescrip + Info.DevDescrip.ProductRevisionOffset);
	if(Info.DevDescrip.SerialNumberOffset)
		strcpy(Info.szSerialNumber, (CHAR *)&Info.DevDescrip + Info.DevDescrip.SerialNumberOffset);

	memset(&PropQuery, 0, sizeof(PropQuery));
	PropQuery.PropertyId = StorageAdapterProperty;
	PropQuery.QueryType = PropertyStandardQuery;
	dwSize = sizeof(Info.AdpDescrip) + sizeof(Info.bzAdpDescripEx);
	bRetVal = ::DeviceIoControl(hDisk, IOCTL_STORAGE_QUERY_PROPERTY, &PropQuery, sizeof(PropQuery),	&Info.AdpDescrip, dwSize, &dwRead, NULL);
	if(bRetVal == FALSE)
	{
		nError = GetLastError();
		if(nError != ERROR_INVALID_FUNCTION)
			assert(0);
	}

	memset(&PropQuery, 0, sizeof(PropQuery));
	PropQuery.PropertyId = StorageDeviceIdProperty;
	PropQuery.QueryType = PropertyStandardQuery;
	dwSize = sizeof(Info.DevIdDescrip) + sizeof(Info.bzDevIdDescripEx);
	Info.DevIdDescrip.NumberOfIdentifiers = sizeof(Info.bzDevIdDescripEx);
	bRetVal = ::DeviceIoControl(hDisk, IOCTL_STORAGE_QUERY_PROPERTY, &PropQuery, sizeof(PropQuery),	&Info.DevIdDescrip, dwSize, &dwRead, NULL);
	if(bRetVal == FALSE)
	{
		nError = GetLastError();
		if(nError != ERROR_NOT_SUPPORTED &&
			nError != ERROR_INVALID_PARAMETER &&
			nError != ERROR_INVALID_FUNCTION)
			assert(0);
	}

	return TRUE;
}
