数据的绑定和IP的验证

      上次的IP映射还存在着两个问题，IP的验证和数据的更新。虽然数据绑定上了，可还是没有及时的更新需要刷新后才能看到更改过的地方。上次的ASPxGridView的数据绑定，

<dxwgv:ASPxGridView ID="ASPxGridView1" runat="server" AutoGenerateColumns="False"
                    CssFilePath="~/App_Themes/Soft Orange/{0}/styles.css" CssPostfix="Soft_Orange"
                    Width="100%" DataSourceID="ObjectDataSource1" KeyFieldName="id" OnRowUpdated="ASPxGridView1_RowUpdated">

数据源：

<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" DataObjectTypeName="ApplicationList.Model.AdressClass" DeleteMethod="delZDCAdress" InsertMethod="insZDCAdress" SelectMethod="getAllZDCAdress" TypeName="ApplicationList.BLL.ServerAdressClass" UpdateMethod="updZDCAdress" OldValuesParameterFormatString="original_{0}"></asp:ObjectDataSource> 

 

它是直接绑定ApplicationList.BLL.ServerAdressClass类中的方法的。我在绑定后修改了config文件但是grid没有及时的更新过来，用刷新后才能看到效果。这是由于我上面的getAllAdress方法中的读取config文件的代码的问题，string allIpStr = ConfigurationManager.ConnectionStrings["ServerAddress"].ConnectionString.ToString();这种方式读取的文件是编译时加载的config文件，修改后的config没有及时加载进去因此就出现问题了。当我把它修改成

            //打开config文件
            Configuration config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
            //找到属性connectionStrings
            ConnectionStringsSection conSection = (ConnectionStringsSection)config.GetSection("connectionStrings");
            //找到name为ServerAdress的string串
            string allIpStr = conSection.ConnectionStrings[connStr].ConnectionString;

后就没有问题了。这种方法是每次打开工程下的config文件然后再读取ConnectionString串。

      另外一个问题是IP的验证，直接贴代码了。。。

 public class IPValidateClass
 {
        private static Regex RegNumber = new Regex("^[0-9]+$");
        private static Regex RegIP = new Regex("//b((?!//d//d//d)//d+|1//d//d|2[0-4]//d|25[0-5])//.((?!//d//d//d)//d+|1//d//d|2[0-4]//d|25[0-5])//.((?!//d//d//d)//d+|1//d//d|2[0-4]//d|25[0-5])//.((?!//d//d//d)//d+|1//d//d|2[0-4]//d|25[0-5])//b");

        public IPValidateClass()
  {}

            char[] reg = { ':'};
            string[] lanNumArr = lanIp.Split(reg);
            string[] wanNumArr = wanIp.Split(reg);

            /*没有用正则表达式的判断

参数model是grid传过来的一行的数据。ASPxGridView挺好用的，可以研究一下。。。
