What is the purpose of the “get” and “set” properties in C#

Question

I saw some get set method to set values. Can anyone tell me the purpose of this?

public string HTTP_USER_NAME
{
      get 
      {
            return UserNam         


        

Answer 1

Standard way to implement properties in C#. UserName and UserPwd are private member variables (string type) of the class where these 2 methods are defined.
