需要调用web.extent....

using System.Web.Script.Serialization;

JavaScriptSerializer json = new JavaScriptSerializer();

List<URL> urlList = new List<URL>();

json.Serialize(urlList);

public class URL
    {
        public int ID { get; set; }
        public string AD { get; set; }
        public int type { get; set; }
        public DateTime date { get; set; }
        public string time { get; set; }
        public string url { get; set; }
        public bool status { get; set; }
    }

添加服务器引用

NextEVWebservice.WebService websvc = new NextEVWebservice.WebService();
JavaScriptSerializer json = new JavaScriptSerializer();
List<URL> urlList = json.Deserialize<List<URL>>(websvc.GetURL(adName));

SPSecurity.RunWithElevatedPrivileges(delegate()
            {
                using (SPSite spSite = new SPSite(siteConfig.NEXTEVPortalWebUrl))
                {
                    using (SPWeb spWeb = spSite.OpenWeb())
                    {

                        SPList m_objList1 = spWeb.Lists["NextEV Contacts"];
                        SPQuery query = new SPQuery();
                        SPListItemCollection list = m_objList1.GetItems(query);
                        foreach (SPItem item in list)
                        {
                            //查
                            string name = item["Nickname"].ToString();

//改
                            spWeb.AllowUnsafeUpdates = true;
                            item["Nickname"] = "测试";
                            item.Update();
                            spWeb.AllowUnsafeUpdates = false;

//删
                            spWeb.AllowUnsafeUpdates = true;
                            item.Delete();
                            spWeb.AllowUnsafeUpdates = false;

break;
}

//增
                        SPList m_objList2 = spWeb.Lists["NextEV Contacts"];
                        SPItem spitem = m_objList2.AddItem();
                        spWeb.AllowUnsafeUpdates = true;
                        spitem["Nickname"] = "测试";
                        spitem.Update();
                        spWeb.AllowUnsafeUpdates = false;
                    }
                }
            });

private void Func()
        {
            System.Timers.Timer t = new System.Timers.Timer(40000); 毫秒
            t.Elapsed += new System.Timers.ElapsedEventHandler(Timer_Click); //Timer_Click是到达时间的时候执行事件的函数

//t.Elapsed += new ElapsedEventHandler((s, e) => OnTimedEvent(s, e, a));
            t.AutoReset = true; //设置是执行一次（false）还是一直执行(true)
            t.Enabled = true;
        }
        private void Timer_Click(Object sender, ElapsedEventArgs e)
        {
           ((System.Timers.Timer)sender).Enabled = false; //有不是时间短触发两次的试试
        }

如果要new带有UI控件的form时如带有webbrowser的form，需要加

BeginInvoke(new Action(() => { 创建或访问控件语句 }));

BeginInvoke(new Action(() =>
{
LetsShow Ls = new LetsShow(backUrl);
Ls.Show();
}));

UDP

发送端

别忘了CheckForIllegalCrossThreadCalls = false;

        private void button1_Click(object sender, EventArgs e)
        {
            System.Timers.Timer t = new System.Timers.Timer();
            t.Elapsed += new System.Timers.ElapsedEventHandler(Timer_Click); //Timer_Click是到达时间的时候执行事件的函数
            //t.Elapsed += new ElapsedEventHandler((s, e) => OnTimedEvent(s, e, a));
            t.AutoReset = true; //设置是执行一次（false）还是一直执行(true)
            t.Enabled = true;
        }

private void Timer_Click(Object sender, ElapsedEventArgs e)
        {
            string sendString = null;//要发送的字符串
            byte[] sendData = null;//要发送的字节数组
            UdpClient client = null;
            IPAddress remoteIP = IPAddress.Parse("192.168.1.102");
            int remotePort = 11000;
            IPEndPoint remotePoint = new IPEndPoint(remoteIP, remotePort);//实例化一个远程端点
            sendString = textBox1.Text;
            sendData = Encoding.Default.GetBytes(sendString);
            client = new UdpClient();
            client.Send(sendData, sendData.Length, remotePoint);//将数据发送到远程端点
            client.Close();//关闭连接
        }

接收

private void button1_Click(object sender, EventArgs e)
        {
            Thread th = new Thread(new ThreadStart(rec));
            th.Start();
        }
        public void rec()
        {
            UdpClient client = null;
            string receiveString = null;
            byte[] receiveData = null;
            //实例化一个远程端点，IP和端口可以随意指定，等调用client.Receive(ref remotePoint)时会将该端点改成真正发送端端点
            IPEndPoint remotePoint = new IPEndPoint(IPAddress.Parse("192.168.1.102"), 0);

while (true)
            {
                client = new UdpClient(11000);
                receiveData = client.Receive(ref remotePoint);//接收数据
                receiveString = Encoding.Default.GetString(receiveData);
                textBox1.Text = receiveString;
                client.Close();//关闭连接
            }
        }

因为webbrowser一般默认为IE5.5或者6 比较低级，js里的data都解析不了，所以需要迫使webbrowser强行加载本机最新IE内核

限制Textbox只能打数字

<asp:TextBox ID="JLR_COST_PRICE" CssClass="input inputwidth_210" runat="server" onkeyup="this.value=this.value.replace(/\D/g,'')" onafterpaste="this.value=this.value.replace(/\D/g,'')"></asp:TextBox>
/[^\d.]/g,'' 小数

/[^\-?\d.]/g,'' 负数小数

/^([1-9]\d*|0)(\.\d*[0-9])?$/

超长

SubStrLength: function (str, len) {
            var strstring = (str == null ? "null" : str);
            return (strstring.length > len ? strstring.substring(0, len) + "..." : strstring);
        }

天朝省市区选择淘宝js版

</div>

$(function () {
    $("#area").cityPicker({
        toolbarTemplate: '<header class="bar bar-nav">\
    <button class="button button-link pull-right close-picker">确定</button>\
    <h1 class="title">选择收货地址</h1>\
    </header>'
    });

});

设置延时

setTimeout(function () { location.href = "MyService.html"; }, 1000);

查询个数据库死锁

SELECT request_session_id spid,OBJECT_NAME(resource_associated_entity_id)tableName
FROM sys.dm_tran_locks
WHERE resource_type='OBJECT '

KILL 79

----------------------------------------------------------------------------------------------------------------------

取消外键约束查询

alter table tsb_user NOCHECK constraint all

---------------------------------------------------------------------------------------------------------------------

取消外键约束

1.查询外键约束
select name
from sys.foreign_key_columns f join sys.objects o on f.constraint_object_id=o.object_id
where f.parent_object_id=object_id('tsb_User')

2.拿到约束名,取消

alter table tsb_User drop constraint Reftsb_Shop12

----------------------------------------------------------------------------------------------------------------------

查看有哪些触发器

select * from sysobjects where xtype='TR'

我的第一个触发器

end

NetJsonjson转类

Newtonsoft.Json.JsonConvert.DeserializeObject<QueryParam>(RequertParams.ToString());

asp.NET .ashx文件使用server.mappath解决方法：

System.Web.HttpContext.Current.Server.MapPath

在类文件中使用：

System.Web.HttpServerUtility server = System.Web.HttpContext.Current.Server;
server.MapPath(...)
