我们有时候需要对用户输入的网站(URL)进行有效性检查，复制代码 代码如下:function CheckUrl(str) {    var RegUrl = new RegExp();    RegUrl.compile("^[A-Za-z]+://[A-Za-z0-9-_]+\.[A-Za-z0-9-_%&?/.=]+$");    if (!RegUrl.test(

第一种字符串流：try            {                var url = "http://paas-logger-openops.myalauda.cn/api/core/logger/log.json";                var httpClient = new HttpClient();                var ht

HttpClient httpClient = new HttpClient();            httpClient.DefaultRequestHeaders.Add("KeepAlive", "false");            var result = httpClient.GetAsync(apiurl + url + "/" + id).Result.Content

HttpClient httpClient = new HttpClient();            httpClient.DefaultRequestHeaders.Add("KeepAlive", "false");            var requestJson = JsonConvert.SerializeObject(model);            HttpC

public class Update    {        private static string UPDATE_SQL = @"UPDATE {0} SET {1} WHERE {2}";//更新语句        private DbHelper _DbHelper = null;  //数据操作类        private string _TableNam

public class Sql    {        #region Class Members        ///         /// DB 帮助对象        ///         private DbHelper _DbHeler;        ///         /// 查询语句        ///         p

public class Select    {        #region Class Members        private static string SELECT_PAGE_SQL = "SELECT TOP {0} * FROM ( SELECT ROW_NUMBER() OVER ({1}) AS ROW , {2} FROM {3} WHERE {4} )

public class Delete    {        private static string DELETE_SQL = @"DELETE FROM {0} WHERE {1}";//删除语句        private DbHelper _DbHelper = null;//数据操作类        private string _TableName = s

public class Insert    {        private DbHelper _DbHelper = null;  //数据操作类        private string INSERT_SQL = @"INSERT INTO {0} ({1}) VALUES ({2})";  //新增语句        private string _Tab

public class DbHelper    {        #region 资源定义        ///         /// 数据库连接        ///         public DbProviderFactory _DbProviderFactory;    //数据库连接        ///         /// 读写连接字符串 

因为你当前环境代码页是437，是美国英语的字符编码你把你环境设置成936就是简体中文字符编码环境了//你当前的是这个Console.OutputEncoding = Encoding.GetEncoding(437);//设置成这样就支持中文编码了Console.OutputEncoding = Encoding.GetEncoding(936);   Console.

全局定时定期执行某些操作看起来是多么自动化的一个问题不过在.net的Global.asax文件中稍微配置即可实现，详细配置如下，感兴趣的朋友可以参考下哈 //引入类库 //add by chairuirui 2013-3-26 void Application_Start(object sender, EventArgs e) { //在应

本文实例讲述了C#检查Windows是否安装了某个服务的方法。分享给大家供大家参考。具体如下：C#代码如下：?1234567891011public static void ISWindowsServiceInstalled(string serviceName){  // get

webAPI方法调用，路由的配置简单小例：1、前台AJAX调用：  $.ajax({            type: "GET",            url: "/openapi/v3/Question/GetTable",            dataType: 'json',            data: {
