我又回来了。 我之前问过一个类似的问题，但即使在上一个答案的帮助下并用问号尝试它，或者我尝试过 AddWithValue 而不是 AddWithValue 我没有任何运气。

我试图将 txt_Naam 更改为 txt_Naam.Text，没有。

还把 [] 放在列名周围，没有运气。它不断给我这个“INSERT INTO 语句中的语法错误。”。

这次我用下面的代码一无所获。可能是小东西，但我无法弄清楚。（再次...）

        protected void btn_final_Click(object sender, EventArgs e)
    {

        string fact_adres = txt_Naam.Text + "," + txt_Anaam.Text + "," + txt_Adres.Text + "," + txt_Toevoeg.Text + "," + txt_Pcode.Text + "," + txt_Plaats.Text + "," + txt_Email.Text ;
        string fact_adres1 = txt_Naam1.Text + "," + txt_Anaam1.Text + "," + txt_Adres1.Text + "," + txt_Toevoeg1.Text + "," + txt_Pcode1.Text + "," + txt_Plaats1.Text + "," + txt_Email1.Text;

        string a = "1";

        OleDbConnection conn = new OleDbConnection();
        conn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0; "
            + "Data Source=|DataDirectory|webwinkel.accdb";

        OleDbCommand cmd = new OleDbCommand();
        cmd.Connection = conn;
        cmd.CommandText = "INSERT INTO Order (factuur_adres_id, verzend_adres_id, totaalprijs) VALUES (?, ?, ?);";

        cmd.Parameters.Add("@factuur_adres", OleDbType.VarChar, 125).Value = fact_adres;
        cmd.Parameters.Add("@verzend_adres", OleDbType.VarChar, 125).Value = fact_adres1;
        cmd.Parameters.Add("@totaal_prijs", OleDbType.VarChar, 7).Value = a;

        try
        {
            conn.Open();
            OleDbDataReader reader = cmd.ExecuteReader();
            reader.Close();
        }

        catch (Exception exc)
        {
            Label1.Text = exc.Message;
        }

        finally
        {
            conn.Close();
            Session["Winkelwagen"] = null;
        }

    }

你的命令文本应该是

cmd.CommandText = "INSERT INTO Order (factuur_adres_id, verzend_adres_id, totaalprijs)   VALUES (@factuur_adres,@verzend_adres, @totaal_prijs)";

更新答案：使用设置参数运行代码，直接传递值并检查它是否有效

    cmd.CommandText = "INSERT INTO Order (factuur_adres_id, verzend_adres_id, totaalprijs)   VALUES ('abc','def','adf')";

当你插入时，你不必使用

cmd.ExecuteNonQuery()

而不是 cmd.ExecuteReader() ??
