在Access數據庫C＃上添加IP地址

Question

如何按照我想要的方式做呢？

我真正想要的是 ：添加IP Range ex。 起始IP文本框[192.168.1.1]-> Netmask文本框[24] =（192.168.1.1-192.168.1.254）IP已添加到數據庫中。

我還希望它檢查用戶是否輸入了正確的IP語法，而不僅僅是一個隨機數，如果錯誤，則顯示一條消息。

我只能用2個文本框來做到這一點：[開始ip]-> [結束ip]，然后單擊[添加按鈕]

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");

                            }
                            else
                            {

                                cmd.Connection = myConn;
                                myConn.Open();
                                cmd.ExecuteNonQuery();
                                actualAddingIps++;

                                myConn.Close();
                            }                             

                    }
                    if(actualAddingIps==totalIpAdding )
                                MessageBox.Show("New IP Range Added");

搜索后，我最終使用此代碼，它解決了我的問題。

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();

         }
