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?。

如何设置连接到主机PC的设备的IP地址?C#窗体

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。。。
