How do I get a distinct, ordered list of names from a DataTable using Linq

Answer 1

try the following

var names = (from dr in dataTable.Rows
             select (string)dr["Name"]).Distinct().OrderBy(name => name);

this should work for what you need

Answer 2

To make it more readable and maintainable, you can also split it up into multiple LINQ statements.

1. First, select your data into a new list, let's call it x1, do a projection if desired
2. Next, create a distinct list, from x1 into x2, using whatever distinction you require
3. Finally, create an ordered list, from x2 into x3, sorting by whatever you desire

Answer 3

var sortedTable = (from results in resultTable.AsEnumerable() select (string)results[attributeList]).Distinct().OrderBy(name => name);
