Filtering Datatable with Select Conditions and Sorting in C#.NET

We can filter data in Datatable using Datatable.Select method. We can also sort the filtered data.
We can also apply AND , OR conditions while filtering and sorting. 

Sample Datatable

private DataTable FillDatatoGrid()
            DataTable dt = new DataTable("Emp");

            //Adding columns to table Emp
            DataColumn colEmpid = new DataColumn("Empid", typeof(System.Int32));
            DataColumn colName = new DataColumn("Name", typeof(System.String));
            DataColumn colDept = new DataColumn("Department", typeof(System.String));

            //Adding columns to datatable
            dt.Columns.AddRange(new DataColumn[] { colEmpid, colName, colDept });

            //Adding data
            dt.Rows.Add(1000, "John Smith Brown", "Finance");
            dt.Rows.Add(1001, "Carry Brown", "Engineering");
            dt.Rows.Add(1002, "Candle Pencil", "Marketing");
            dt.Rows.Add(1003, "Graham Bell", "Engineering");
            dt.Rows.Add(1004, "Peter Kevin", "Finance & Engineering");

            return dt;

Example program to Filtering Data using Datatable.Select Method , AND, OR Conditions and Sorting

//Fill data into datatable. FillDatatoGrid method is defined above
        DataTable dataTable=FillDatatoGrid();

         //using Datatable.Select Method
        DataRow[] rowsFiltered = dataTable.Select("Empid=1000");

        DataRow[] rowsFilteredSorting = dataTable.Select("Empid=1000","Empid desc" );

         //Filtering datatable with OR Conditoin and Sorting
        DataRow[] rowsFilteredConditionOR = dataTable.Select("Empid=1000 OR Empid=1001", "Empid desc");

        //Filtering datatable with AND Conditoin
         //Strings should be enclosed with single quotes
        DataRow[] rowsFilteredConditionAND = dataTable.Select("Empid=1001 AND Name='Carry Brown'", "Empid desc");

Please note, strings should be enclosed with single quotes while filtering data using Datatable.Select method.
