What is the purpose of IsFinal property in C# Reflection?

Answer:

The IsFinal property of MethodBase class gets a value indicating whether this method is final.It returns true if this method is final; otherwise, false. It is defined as

public bool IsFinal { get; }

e.g.

Suppose we have

public class Employee : IMyInterface

    {

        public int property1 { get; set; }       

        public int EmployeeId { get; set; }

        public string EmployeeName { get; set; }

        public virtual int EmployeeAge { private set;   get; } //read-only property

        public virtual string EmployeeSalary { set; private get; } //write-only property 

    }



    interface IMyInterface

    {

        int property1 { get; set; }

        

    }

And we want to get only the interface property name. Use the below code

typeof(Employee)

                .GetProperties()

                .Where(p => p.GetAccessors()[0].IsFinal)               

                 .ToList()

                .ForEach(i => Console.WriteLine(i.Name));
