LINQ: Get all the values from a column in a DataTable in C#
You can get the values from a named column in the DataTable using a single line of code in LINQ.

Steps:

  1. Convert the DataTable object to Enumerable().
  2. Apply the select clause with the column name as field name.
  3. Cast it to a string array.
    C#
    string[] strSummCities = dtTemp1.AsEnumerable().Select(s => s.Field<string>("City")).ToArray<string>();

This is great, just wondering if there was a concise way of making it select distinct values?

cheers
