Q: .Net DataTable Select as Sql Brackets Is there a wildcard form to assume İ and I as same characters for .net datatable.select function as sql brackets do?
For example this SQL query returns either 'JESSİCA' or 'JESSICA'
select * from Customers where name = 'JESS[Iİ]CA'.

A: Make your life easier and  use LINQ-TO-DataTable:
var query = from row in dataTable.AsEnumerable()
            let name = row.Field<string>("name")
            where name == "JESSİCA" || name == "JESSICA"
            select row;

If you want a new  DataTable use CopyToDataTable(), if you want a DataRow[] use ToArray().
If you want to compare case-insensitve and the list of accepted names can increase:
string names = { "JESSİCA", "JESSICA" };
var query = from row in dataTable.AsEnumerable()
            let name = row.Field<string>("name")
            where names.Contains(name, StringComparer.CurrentCultureIgnoreCase)
            select row;
