类出来了，用它读写Mac地址就是小菜一碟了，下面是读写Mac地址的示例代码：
private void btnRead_Click(object sender, EventArgs e)
{
txtMAC1.Text = reg.ReadValue(YFReg.HKEY.HKEY_LOCAL_MACHINE, @"Comm\DM9CE1\Parms", "SoftwareMacAddress0");
txtMAC2.Text = reg.ReadValue(YFReg.HKEY.HKEY_LOCAL_MACHINE, @"Comm\DM9CE1\Parms", "SoftwareMacAddress1");
txtMAC3.Text = reg.ReadValue(YFReg.HKEY.HKEY_LOCAL_MACHINE, @"Comm\DM9CE1\Parms", "SoftwareMacAddress2");
txtMAC4.Text = reg.ReadValue(YFReg.HKEY.HKEY_LOCAL_MACHINE, @"Comm\DM9CE1\Parms", "SoftwareMacAddress3");
txtMAC5.Text = reg.ReadValue(YFReg.HKEY.HKEY_LOCAL_MACHINE, @"Comm\DM9CE1\Parms", "SoftwareMacAddress4");
txtMAC6.Text = reg.ReadValue(YFReg.HKEY.HKEY_LOCAL_MACHINE, @"Comm\DM9CE1\Parms", "SoftwareMacAddress5");
}
private void btnWrite_Click(object sender, EventArgs e)
{
int intRet = 0;
intRet += reg.WriteValue(YFReg.HKEY.HKEY_LOCAL_MACHINE, @"Comm\DM9CE1\Parms", "SoftwareMacAddress0", txtMAC1.Text);
intRet += reg.WriteValue(YFReg.HKEY.HKEY_LOCAL_MACHINE, @"Comm\DM9CE1\Parms", "SoftwareMacAddress1", txtMAC2.Text);
intRet += reg.WriteValue(YFReg.HKEY.HKEY_LOCAL_MACHINE, @"Comm\DM9CE1\Parms", "SoftwareMacAddress2", txtMAC3.Text);
intRet += reg.WriteValue(YFReg.HKEY.HKEY_LOCAL_MACHINE, @"Comm\DM9CE1\Parms", "SoftwareMacAddress3", txtMAC4.Text);
intRet += reg.WriteValue(YFReg.HKEY.HKEY_LOCAL_MACHINE, @"Comm\DM9CE1\Parms", "SoftwareMacAddress4", txtMAC5.Text);
intRet += reg.WriteValue(YFReg.HKEY.HKEY_LOCAL_MACHINE, @"Comm\DM9CE1\Parms", "SoftwareMacAddress5", txtMAC6.Text);
if (intRet > 0)
{
MessageBox.Show("更改失败");
}
}
