My goto is Console WriteLine  Serialize dictionary ToList         Make sure you include the package using static System Text Json JsonSerializer

There are so many ways to do this  here is some more  string Join Environment NewLine  dictionary Select a   gt    quot  a Key    a Value  quot     dictionary Select a   gt    quot  a Key    a Value  Environment NewLine  quot    Aggregate  a b   gt a b   new String dictionary SelectMany a   gt    quot  a Key    a Value   Environment NewLine  quot   ToArray     Additionally  you can then use one of these and encapsulate it in an extension method  public static class DictionaryExtensions       public static string ToReadable lt T V gt  this Dictionary lt T  V gt  d           return string Join Environment NewLine  d Select a   gt    quot  a Key    a Value  quot                 And use it like this  yourDictionary ToReadable
