在反射和泛型中经常会使用到Type类,获取Type的最常用的方法是 obj.GetType(),和typeof(T).在获取泛型的type时有些小坑. public static void Main(string[] args) { A a = new B { a = "a", b = "b", c = "c", }; B c = new B { a = "a", b = "b", c = "c&
c# GetType()和typeof()的区别 C#中任何对象都具有GetType()方法,返回Type类型的当前对象的类型. GetType()是基类System.Object的方法,因此只有建立一个实例之后才能够被调用. typeof(x)中的x,必须是具体的类名.类型名称等,不可以是变量名称: The typeof operator is used to obtain the System.Type object for a type. typeof的参数只能是int,string,
typeof: The typeof operator is used to obtain the System.Type object for a type. 运算符,获得某一类型的 System.Type 对象. Type t = typeof(int); GetType: Gets the Type of the current instance. 方法,获取当前实例的类型. int i = 10;Console.WriteLine(i.G
typeof: 是运算符,获得某一类型的 System.Type 对象. Int32 t = new Int32(); Type t = typeof(int); GetType: 是方法,获取当前实例的类型. int i = 10; Console.WriteLine(i.GetType()); 区别: GetType()是基类System.Object的方法,因此只有建立一个实例之后才能够被调用(初始化以后) Typeof()的参数只能是int,string,String,自定义类型,且不能

之前我老大去网上找了一个DAL里面操作数据库的通用类: public class DALHelper { public static List<T> Search<T>() where T : SH_SetBase { using (var db = new ShopContext()) { var dbSet = GetDBSet(db, typeof(T)) as DbSet<T>; if (typeof(T).IsSubclassOf(typeof(SH_SetB
