我有一个Modbus TCP/IP到Modbus RTU转换器,默认IP为192.168.0.1。我需要开发一个小型c#Winform应用程序,将该设备的IP地址更改为任何所需的IP地址。我该怎么做?。
您可以使用WMI(Windows Management Instrumentation)来完成此操作。
首先,您必须将System.Management
的引用添加到您的项目中。
其次,您需要按名称查找网络连接的NetworkInterface
:
using System.Net.NetworkInformation;
using System.Management;
public class NetworkManager
{
public static NetworkInterface GetNetworkInterface(string sName)
{
NetworkInterface NetInterface = null;
// Precondition
if (sName == "") return null;
NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface ni in interfaces)
{
if (ni.Name == sName)
{
NetInterface = ni;
break;
}
}
return NetInterface;
}
第三,您必须为NetworkInterface
:创建一个ManagementObject
public static ManagementObject GetNetworkAdapterManagementObject(NetworkInterface NetInterface)
{
ManagementObject oMngObj = null;
// Precondition
if (NetInterface == null) return null;
string sNI = NetInterface.Id;
ManagementClass oMC = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection oMOC = oMC.GetInstances();
foreach (ManagementObject oMO in oMOC)
{
string sMO = oMO["SettingID"].ToString();
if (sMO == sNI)
{
// Found
oMngObj = oMO;
break;
}
}
return oMngObj;
}
Fours,你可以设置ipad与:
public static bool SetIPAdress(ManagementObject oMO, string[] saIPAdress, string[] saSubnetMask)
{
bool bErg = false;
try
{
// Precondition
if (oMO == null) return false;
if (saIPAdress == null) return false;
if (saSubnetMask == null) return false;
// Get ManagementBaseObject
ManagementBaseObject oNewIP = null;
oNewIP = oMO.GetMethodParameters("EnableStatic");
oNewIP["IPAddress"] = saIPAdress;
oNewIP["SubnetMask"] = saSubnetMask;
// Invoke
oMO.InvokeMethod("EnableStatic", oNewIP, null);
// Alles ok
bErg = true;
}
catch (Exception ex)
{
Console.WriteLine("SetIPAdress failed: " + ex.Message);
}
return bErg;
}
}
现在您可以使用它,例如在按钮点击事件处理程序中:
private void button1_Click(object sender, EventArgs e)
{
string sConn = "LAN-Verbindung";
NetworkInterface oNI = NetworkManager.GetNetworkInterface(sConn);
ManagementObject oMO = NetworkManager.GetNetworkAdapterManagementObject(oNI);
string sIPAdress = "192.168.1.1";
string sSubnetMask = "255.255.255.0";
string[] saIPAdress = {sIPAdress};
string[] saSubnetMask = {sSubnetMask};
if (NetworkManager.SetIPAdress(oMO, saIPAdress, saSubnetMask))
{
Console.WriteLine("Yes...");
}
}
根据您电脑上的策略,您可能必须以管理员身份运行程序。。。
