Question

I’d like to create an array of unique items from a datatable column. I know how to create a dataview…

DataView view = new DataView(table);
DataTable distinctValues = view.ToTable(true, "Column1", "Column2" ...);

Is it a similar approach for an array? Thanks in advance.

You can use LINQ

DataTable myDataTable = new DataTable();
//......
string[] uniqueItems = myDataTable.AsEnumerable()
                                  .Select(r=> r.Field<string>("MyColumn"))
                                  .Distinct()
                                  .ToArray();
