用途：方便js操作查询json数据。

使用方法：只需要引用linq.js即可。
查询方法：
一、where查询
var myList = [
{ Name: "Jim", Age: 20 },
{ Name: "Kate", Age: 21 },
{ Name: "Lilei", Age: 18 },
{ Name: "John", Age: 14 },
{ Name: "LinTao", Age: 25 }
];
var arrRes = Enumerable.From(myList).Where("x=>x.Name=='Jim'").ToArray();
二、排序：OrderBy
var myList = [
{ Name: "Jim", Age: 20 },
{ Name: "Kate", Age: 21 },
{ Name: "Lilei", Age: 18 },
{ Name: "John", Age: 14 },
{ Name: "LinTao", Age: 25 }
];
var arrRes = Enumerable.From(myList).OrderBy("x=>x.Age").ToArray();//降序OrderByDescending()
三、去重：Distinct
var myList = [
{ Name: "Jim", Age: 20 },
{ Name: "Kate", Age: 20 },
{ Name: "Lilei", Age: 20 },
{ Name: "John", Age: 14 },
{ Name: "LinTao", Age: 25 }
];
var arrRes = Enumerable.From(myList).Distinct("x=>x.Age").ToArray();
四、遍历：ForEach
var myList = [
{ Name: "Jim", Age: 20 },
{ Name: "Kate", Age: 20 },
{ Name: "Lilei", Age: 20 },
{ Name: "John", Age: 14 },
{ Name: "LinTao", Age: 25 }
];
Enumerable.From(myList).ForEach(function(value, index){
document.write("值="+value+",索引="+index);
});
五、取唯一对象：First、FirstOrDefault、Last、LastOrDefault、Single、SingleOrDefault
var myList = [
{ Name: "Jim", Age: 20 },
{ Name: "Kate", Age: 20 },
{ Name: "Lilei", Age: 20 },
{ Name: "John", Age: 14 },
{ Name: "LinTao", Age: 25 }
];
var arrRes = Enumerable.From(myList).FirstOrDefault("x=>x.Age>18");
六、Skip、Take
Enumerable.Range(1,10).Skip(5)//结果[6,7,8,9,10]
Enumerable.Range(1,10).Take(5)//结果[1,2,3,4,5]
)
