代码改变生活

1、Linq语法基础 var number = 2008; var strs = new string[] { "2008", "08", "05" }; var ui = new UserInfo(); ui.ID = 1; ui.Name = "数据"; //对象初始化

1、Linq与lambda使用 http://www.cnblogs.com/knowledgesea/p/3897665.html

1、Linq https://docs.microsoft.com/zh-cn/dotnet/csharp/linq/query-expression-basics https://docs.microsoft.com/zh-cn/dotnet/csharp/linq/write-linq-queries

LINQ查询操作符 ZKWebForm1219_20180114Entities db = new ZKWebForm1219_20180114Entities(); protected void Button1_Click(object sender, EventArgs e) { //.First -返回集合中的第一个元素；不延迟

1、Linq基本语法 //====== ZKWebForm1219_20180114Entities db = new ZKWebForm1219_20180114Entities(); protected void Button1_Click(object sender, EventArgs e) { var ss =

//这么一个LIST， 最终想得到的结果如下： List list = new List(); list.Add(new TestData() { Name="A", Count=3,BatNum="001"}); list.Add(new TestData() { Name = "A", Count = 3,BatNum="001"

1、测试类  (vs2013) public class models { public int id { set; get; } public string Name { set; get; } public string Phone { set; get; } public string Address { set

1.一对多关系查询： var q=from c in db.Students       from n in c.orders       where c.City=='wuhan'       select  n; 2.多对多关系查询：  var q=from e in db.Students        from et in e.name        where e

1、 ZKWebForm1219_20171128Entities db = new ZKWebForm1219_20171128Entities(); protected void Button1_Click(object sender, EventArgs e) { //where:简单形式=================

1、 //IsDigit()：指定的字符是否在十进制数字 string datatSource = "Visual Studio 2010 team"; var values = from u in datatSource where char.IsDigit(u)

1、数据查询 using System; using System.Collections.Generic; using System.Data; using System.Linq; using System.Text; using System.Threading.Tasks; namespace ConsoleApp1 { class Program { ...
