C#利用win32 Api 修改本地系统时间、获取硬盘序列号，可以用于软件注册机制的编写！
代码如下:
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
namespace Fengyun
{
public class Win32
{
#region 修改本地系统时间
[DllImport("Kernel32.dll")]
private extern static void GetSystemTime(ref SYSTEMTIME lpSystemTime);
[DllImport("Kernel32.dll")]
private extern static uint SetLocalTime(ref SYSTEMTIME lpSystemTime);
[StructLayout(LayoutKind.Sequential)]
private struct SYSTEMTIME
{
public ushort wYear;
public ushort wMonth;
public ushort wDayOfWeek;
public ushort wDay;
public ushort wHour;
public ushort wMinute;
public ushort wSecond;
public ushort wMilliseconds;
}
/// <summary>
/// 将本地时间与sqlserver服务器时间同步
/// </summary>
/// <param name="SqlServerTime">时间</param>
public static void SetTime(DateTime SqlServerTime)
{
SYSTEMTIME st = new SYSTEMTIME();
st.wYear = Convert.ToUInt16(SqlServerTime.Year);
st.wMonth = Convert.ToUInt16(SqlServerTime.Month);
st.wDay = Convert.ToUInt16(SqlServerTime.Day);
st.wHour = Convert.ToUInt16(SqlServerTime.Hour);
st.wMilliseconds = Convert.ToUInt16(SqlServerTime.Millisecond);
st.wMinute = Convert.ToUInt16(SqlServerTime.Minute);
st.wSecond = Convert.ToUInt16(SqlServerTime.Second);
SetLocalTime(ref st);
}
#endregion
#region 获取硬盘序列号
[DllImport("kernel32.dll")]
private static extern int GetVolumeInformation(
string lpRootPathName,
string lpVolumeNameBuffer,
int nVolumeNameSize,
ref int lpVolumeSerialNumber,
int lpMaximumComponentLength,
int lpFileSystemFlags,
string lpFileSystemNameBuffer,
int nFileSystemNameSize
);
/// <summary>

public static string GetDiskVolume(string drvID)
{
const int MAX_FILENAME_LEN = 256;
int retVal = 0;
int lpMaximumComponentLength = 0;
int lpFileSystemFlags = 0;
string lpVolumeNameBuffer = null;
string lpFileSystemNameBuffer = null;
int i = GetVolumeInformation(
drvID + @":\",
lpVolumeNameBuffer,
MAX_FILENAME_LEN,
ref retVal,
lpMaximumComponentLength,
lpFileSystemFlags,
lpFileSystemNameBuffer,

return retVal.ToString("x");
}
