  • Learn the language and rules of development, understand WHY and WHAT mean mistakes, they are not just that you are issued. Unfortunately, nobody will do it for you. Common questions like "I have a mistake, what should I do?" do not carry any useful information to SO. Explain what you know, what is not, and what exactly you do not understand - then, you see, people will catch up. - Daniel Protopopov

In this case, the modifier

 public const

Applies only to the field string Sm = "Samsung"; . The following fields

 string Lg_ = "LG"; string Sn = "Sony";

They are ordinary class fields, not constants and not static.

To solve, you must either use this modifier for all three fields.

 public const string Sm = "Samsung"; public const string Lg_ = "LG"; public const string Sn = "Sony";

Or use a comma instead of a semicolon:

 public const string Sm = "Samsung", string Lg_ = "LG", string Sn = "Sony";
