Filter one DataTable and store it another DataTable

Dear friend 
Here you can see that a First data is store in DataTable (dt) but i want to filter that DataTable where value "SAM" is not present.

so you follow this way.

int i=0;
          DataTable dtt=new DataTable();
            dtt.Columns.Add("SSN", typeof(string));
            dtt.Columns.Add("NAME", typeof(string));
            dtt.Columns.Add("ADDR", typeof(string));
            dtt.Columns.Add("AGE", typeof(int));

            DataTable dt = new DataTable();
            dt.Columns.Add("SSN", typeof(string));
            dt.Columns.Add("NAME", typeof(string));
            dt.Columns.Add("ADDR", typeof(string));
            dt.Columns.Add("AGE", typeof(int));
            // Showing how to set Primary Key(s) in a Data table (Although it's not compulsory to have one)
            DataColumn[] keys = new DataColumn[1];
            keys[0] = dt.Columns[0];
            dt.PrimaryKey = keys;
            dt.Rows.Add("203456876", "John", "12 Main Street, Newyork, NY", 15);
            dt.Rows.Add("203456877", "SAM", "13 Main Ct, Newyork, NY", 25);
            dt.Rows.Add("203456878", "Elan", "14 Main Street, Newyork, NY", 35);
            dt.Rows.Add("203456879", "Smith", "12 Main Street, Newyork, NY", 45);
            dt.Rows.Add("203456880", "SAM", "345 Main Ave, Dayton, OH", 55);
            dt.Rows.Add("203456881", "Sue", "32 Cranbrook Rd, Newyork, NY", 65);
            dt.Rows.Add("203456882", "Winston", "1208 Alex St, Newyork, NY", 65);
            dt.Rows.Add("203456883", "Mac", "126 Province Ave, Baltimore, NY", 85);
            dt.Rows.Add("203456884", "SAM", "126 Province Ave, Baltimore, NY", 95);
          //  DataRow[] DataTable.Select(string filterExpression, string sort)
            foreach (DataRow o in dt.Select("NAME <> 'SAM'"))
              //  Console.WriteLine("\t" + o["SSN"] + "\t" + o["NAME"] + "\t" + o["ADDR"] + "\t" + o["AGE"]);
                string aa = o["SSN"].ToString();
                string ab = o["NAME"].ToString();
                string ac = o["ADDR"].ToString();
                string ad = o["AGE"].ToString();

                //for (int i = 0; i < dt.Rows.Count; i++)
                    dtt.Rows[i][0] = aa;
                    dtt.Rows[i][1] = ab;
                    dtt.Rows[i][2] = ac;
                    dtt.Rows[i][3] = ad;
                    i = i + 1;
