Как узнать тип переменной C#

Для определения типа переменной в C# существует функция GetType()

Небольшая демонстрация

using System; public class MyBaseClass { } public class MyDerivedClass: MyBaseClass { } public class Test { public static void Main() { MyBaseClass myBase = new MyBaseClass(); MyDerivedClass myDerived = new MyDerivedClass(); object o = myDerived; MyBaseClass b = myDerived; Console.WriteLine("mybase: Type is {0}", myBase.GetType()); Console.WriteLine("myDerived: Type is {0}", myDerived.GetType()); Console.WriteLine("object o = myDerived: Type is {0}", o.GetType()); Console.WriteLine("MyBaseClass b = myDerived: Type is {0}", b.GetType()); } } // The example displays the following output: // mybase: Type is MyBaseClass // myDerived: Type is MyDerivedClass // object o = myDerived: Type is MyDerivedClass // MyBaseClass b = myDerived: Type is MyDerivedClass

int n1 = 12; int n2 = 82; long n3 = 12; Console.WriteLine("n1 and n2 are the same type: {0}", Object.ReferenceEquals(n1.GetType(), n2.GetType())); Console.WriteLine("n1 and n3 are the same type: {0}", Object.ReferenceEquals(n1.GetType(), n3.GetType())); // The example displays the following output: // n1 and n2 are the same type: True // n1 and n3 are the same type: False

Результат

n1 and n2 are the same type: True n1 and n3 are the same type: False

Хочу обратить Ваше внимание на то, что в языке Си такой функции нет.

В С++ есть похожая функция typeid().name()

В Python есть type() а также немного другая функция isinstance() с помощью которой можно решить эту же задачу.
