在C＃中为Windows设置和获取DHCP选项

Question

Using C#, I'm trying to set dhcp option 12 using ManageDHCP.dll . In a nutshell, this is what I'm doing:

var dhcpManager = new DHCPManager(dhcpServerName)
var hostRecord = new HostInfo
               {
                  Name = deviceDhcpName,
                  IPv4 = deviceIpAddress,
                  IsReserved = true,
                  MAC = deviceMacAddress
               };

dhcpManager.SetRecord(dhcpServerScope, hostRecord);

String hostName = deviceDhcpName + "." + dnsZoneName;
var hostnameOpt = new Option
                  {
                     ID = 12,
                     Values = new List<string> { hostName }
                  };
dhcpManager.SetOption(hostnameOpt, dhcpServerScope, deviceIpAddress);

The thing is, is that it just dies at this point and the logs don't record an exception. So I was thinking maybe the format I'm sending it is not correct. So I went to try and get an option. So instead, after creating the reservation, with SetRecord function above - I called this instead, just to try an see if I could get an option to see the correct format:

Option test = dhcpManager.GetOption(3, dhcpServerScope, deviceIpAddress);

Which throws this exception:

ManageDHCP.DhcpException: DhcpGetOptionInfo at ManageDHCP.DHCPManager._GetOption(OptionTarget target, UInt32 optionID, String subnet, String reservedIP)

I'm new to C# and I'm not really sure what's causing this exception. Here is a link to the source code for ManageDHCP. What am I doing wrong? Is my format incorrect?

似乎32位dll的setOption函数不起作用（DhcpGetOptionInfo引发异常），因此我切换到64位dll。
