Filtering data table using LINQ query

DataTable dtEmployees = new DataTable();
            
            //Columns of data table
            dtEmployees.Columns.Add("Name", typeof(string));
            dtEmployees.Columns.Add("Salary", typeof(double));

           //Adding some rows in the data table
            dtEmployees.Rows.Add("John", 50000);
            dtEmployees.Rows.Add("Joseph",25000);
            dtEmployees.Rows.Add("Jai", 15000);

var result = from row in dtEmployees.AsEnumerable()
                         where row.Field("Salary") > 20000
                         select row.Field("Name");

 foreach (string name in result)
            {
                Console.Write(name);
            }
