Question

Is there any way to get some list of all Sql Data Types on c#?

I know that we have a Enum called SQlDbType which contains all Sql Data Types, but can we convert an Enum to an array of strings?

I only want to get some list with all Sql Data Types, instead of writing them one by one and adding them into my array of strings.

Answer 1

Enum to an array of strings is pretty easy:

var names = Array.ConvertAll((SqlDbType[]) Enum.GetValues(typeof(SqlDbType)),
                             type => type.ToString());

or using LINQ:

var names = Enum.GetValues(typeof(SqlDbType))
                .Cast<SqlDbType>()
                .Select(x => x.ToString())
                .ToArray();

Or more pleasantly using my Unconstrained Melody library, either as an array or (more efficiently) an immutable list:

string[] names = Enums.GetNamesArray<SqlDbType>();

IList<string> namesList = Enums.GetNames<SqlDbType>();
