Linq自学系列（一）

1，首先是匿名变量及类型          private   void  var1()         {              // 匿名变量，定义时必须赋值，不能为null             var age  =   26 ;             var username  =   " zhuye " ;             var userlist  =   new [] {  " a " ,  " b " ,  " c "  }; // 字符串数组              // 匿名类型             var data  =   new  { name  =   " LIN " , age  =   26  };              string  s  =  data.name; // 可给对应类型赋值              int  i  =  data.age;         } 2，自动属性，懒人的最爱          public   class  User         {              private   int  _id;              private   string  _name;              private   int  _age;              public   int  Id             {                  get  {  return  _id; }                  set  { _id  =  value; }             }              public   string  Name             {                  get  {  return  _name; }                  set  { _name  =  value; }             }              public   int  Age             {                  get  {  return  _age; }                  set  { _age  =  value; }             }         }          public   class  User1         {              public   int  Id {  get ;  set ; }              public   string  Name {  get ;  set ; }              public   int  Age {  get ;  set ; }         }
