delphi Using records as key in TDictionary

Question

Can you use a record as a Key value in TDictionary? I want to find objects based on combination of string, integer and integer.

TUserParKey=record
  App:string;
         


        

Answer 1

My best approach should be to joint the default hash code of the base types.

For instance:

Value.App.GetHashCode + Value.ID.GetHashCode + Value.Nr.GetHashCode;
