Question

如何按我想要的方式完成？

我真正想要的是什么：添加IP范围ex。启动IP文本框[192.168.1.1] - ＆gt;网络掩码文本框[24] =（192.168.1.1 - 192.168.1.254）在数据库中添加了IP。

此外，我希望它检查用户是否使用正确的IP语法而不是随机数字，如果错误则显示消息。

我只是设法用2个文本框[start ip] - ＆gt; [结束ip]然后[添加按钮]

if (CheckIPValid(txtstartip.Text)&&(CheckIPValid(txtendip.Text)))
            {

                    if (!(txtstartip.Text.StartsWith("0"))&&(!(txtstartip.Text.StartsWith("0"))))
                    {
                            string startip = txtstartip.Text;
                            string endip = txtendip.Text;
                    string insertinip = "";
                            string usingip = startip.Substring(0, startip.LastIndexOf(".") + 1);
                            startip = startip.Substring(startip.LastIndexOf(".") + 1);
                            endip = endip.Substring(endip.LastIndexOf(".") + 1);

                            int endipCount = Convert.ToInt16(endip);
                            int startipCount = Convert.ToInt16(startip);
                            if (endipCount > startipCount)
                            {
                        int totalIpAdding = endipCount - startipCount;
                        int actualAddingIps = 0;
                    for (int i = startipCount; i <= endipCount; i++)
                    {
                            insertinip = "";
                            insertinip  = usingip + "" + i.ToString();
                            if(checkDuplicateIP(insertinip))
                            {

                                MessageBox.Show("The IP "+ insertinip + " is already in Database");

搜索后我最终使用此代码，它解决了我的问题。

IPSegment ip = new IPSegment(txtip.Text.ToString(), SubNetMask());

                Console.WriteLine(ip.NumberOfHosts);
                Console.WriteLine(ip.NetworkAddress.ToIpString());
                Console.WriteLine(ip.BroadcastAddress.ToIpString());
                Console.WriteLine("===");

foreach (var host in ip.Hosts())
                    {

                 string query = "insert into tblIPAddress(IP_Address) values('" + host.ToIpString() + "')";
                 OleDbCommand cmd = new OleDbCommand(query);
                 cmd.Connection = myConn;
                 myConn.Open();
                 cmd.ExecuteNonQuery();
                 myConn.Close();

         }
