Question

我已经在图片中构建了一个数据表..我将在一个文本框中进行句子，如：＆＃34;男孩踢球＆＃34;我需要检查该句子中的每个单词，如果它存在于该表中，那么它将显示列表框中包含该单词的列的名称，例如：（=＆gt; Article）。我做了所有的步骤，但我在检查和显示包含单词的列的名称的最后一步停止.. 我只是一个初学者，所以我很难编程完成最后一步，任何人都可以帮助我吗？ datatable has three columns "Article","Noun","verb" and rows values:"the","boy","kick" and so on in other rows

 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();
        dataGridView1.DataSource = dt;


        string s = textBox1.Text;
        string[] st = s.Split(' ');

现在如何检查st []中的每个单词是否存在于表中他将在

中显示他找到的单词和列名

using System.Data;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            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");
                }
            }
        }
    }
}

输出：

Word = the Column = Article

Word = ball Column = Noun

Word = eat Column = Verb

Word = a Column = Article

Word = boy Column = Noun
