lambda练手

public class Lambda { public Lambda() { Expression<Func<int, int>> exp = x => x / 8; int result = exp.Compile()(8888); DisplayHelper.ConInline("Lambda 表达树结果：" + result); //筛选姓名不为空，年龄>18的 Expression<Func<Persion, string>> exp3 = (Persion p) => !string.IsNullOrEmpty(p.name)&&p.age>18?"姓名：" + p.name + " 年龄：" + p.age+" 符合条件":p.name+"不符合条件"; //构造数据 List<Persion> list = new List<Persion>(); for (int i = 0; i < 5; i++) { Persion p1 = new Persion(); p1.name = "admin" + i; p1.age = 15 + i; list.Add(p1); } //筛选并打印结果 foreach (Persion p in list) { string str = exp3.Compile()(p); DisplayHelper.ConInline(str); } } } public class Persion { public string name { get; set; } public int age { get; set; } }
