Question

我想从数据库中选择一个句子，但我不知道如何编写代码。我将通过从文本框中读取行来搜索数字。

                for (int i = 0; i < lines.GetUpperBound(0); i++)
                {
                    OleDbCommand command = new OleDbCommand();
                    command.Connection = connection;
                    string query1 = "SELECT TOP 1 * FROM SolozinnenTabel WHERE Faciliteitnummer = " + lines[i] + " AND Paragraaf LIKE '" + AlineaKinderenNaam + "%' ORDER BY rnd(ID)";
                    command.CommandText = query1;
                    OleDbDataReader reader1 = command.ExecuteReader();
                    while (reader1.Read()) {
                        RichAccoText.Text = RichAccoText.Text + reader1["Zin"].ToString();
                        RichFacilityText.Lines = RichFacilityText.Lines.Where(line => line != lines[i]).ToArray();

                    }
                }

此代码有效但我只能搜索一行并在文本框中搜索它们。所以我想要这样的东西：

string query1 =＆＃34; SELECT TOP 1 * FROM CombizinnenTabel WHERE（Faciliteitnummer1 =＆＃34; + lines [a] +＆＃34; AND Faciliteitnummer2 =＆＃34; + lines [a] +＆＃34 ;）和Paragraaf LIKE＆＃39;＆＃34; + AlineaAccommodatieNaam +＆＃34;％＆＃39; ORDER BY rnd（ID）＆＃34 ;;

行[a] = 80，但我想搜索：

如果Faciliteitnummer1 = lines [80] en Faciliteitnummer2 = lines [48]和Faciliteitnummer3 = lines [18]，那么选择这句话......

如果（Faciliteitnummer1 = lines [80] en Faciliteitnummer2 = lines [10]和Faciliteitnummer3 = lines [0]，则选择这句话......
