        {
            InitializeComponent();

            DataTable dt = new DataTable();
            DataColumn article = new DataColumn("Article", typeof(string));
            dt.Columns.Add(article);
            DataColumn noun = new DataColumn("Noun", typeof(string));
            dt.Columns.Add(noun);
            DataColumn verb = new DataColumn("Verb", typeof(string));
            dt.Columns.Add(verb);
            DataRow dr = dt.NewRow();
            dr["Article"] = "the";
            dr["Noun"] = "boy";
            dr["Verb"] = "kick";
            dt.Rows.Add(dr);
            dr = dt.NewRow();

            DataRow dd = dt.NewRow();
            dd["Article"] = "a";
            dd["Noun"] = "ball";
            dd["Verb"] = "eat";
            dt.Rows.Add(dd);
            dd = dt.NewRow();

            string s = "the boy eat the ball"; //textBox1.Text;
            string[] st = s.Split(' ');
        
            foreach (var str in st)
            {
                foreach (DataRow rows in dt.Rows)
                {
                    if(str == rows["Article"].ToString())
                        Console.WriteLine("Word=" + str + "    Column=Article");
                    else if (str == rows["Noun"].ToString())
                        Console.WriteLine("Word=" + str + "    Column=Noun");
                    else if (str == rows["Verb"].ToString())
                        Console.WriteLine("Word=" + str + "    Column=Verb");
                }
            }
        }
    }
}

Output:

Word=the Column=Article

Word=ball Column=Noun

Word=eat Column=Verb

Word=a Column=Article

Word=boy Column=Noun
