Checking if the object is of same type

Question

Hello I need to know how to check if the object of the same type in C#.

Scenario:

class Base_Data{}  class Person : Base_Data { } class Phone  : Base_data { }  class AnotherClass {    public void CheckObject(Base_Data data)    {          if (data.Equals(Person.GetType()))          { //<-- Visual Studio 2010 gives me error, says that I am using 'Person' is a type and not a variable.          }     } }

You could use the is operator:

if (data is Person) {     // `data` is an instance of Person } 

Another possibility is to use the as operator:

var person = data as Person; if (person != null) {     // safely use `person` here } 

Or, starting with C# 7, use a pattern-matching form of the is operator that combines the above two:

if (data is Person person) {     // `data` is an instance of Person,     // and you can use it as such through `person`. }
