以下是我用来向Access 2007数据库添加新行的代码块。这段代码不在我的db.open和db.close代码之外。我之前收到连接错误，但我注释掉了db.dispose行，现在它给了我一个语法错误。我尝试过做一个rDS.InsertCommand。这没有返回任何错误，但它没有将新行插入数据库。我之前从未在我的代码中做过这样的事情，所以如果我以正确的方式解决这个问题，我就无法做到这一点。我想知道问题是否是在我的Form1_Load中建立数据库连接的时候。我使用了Microsoft.ACE.OLEDB.12.0，但在搜索我的错误的帮助时，似乎大多数人一直在使用Microsoft.JET.OLEDB.4.0。我尝试切换到那个，但这也给了我一个错误。我真的不确定问题是什么，我希望我能得到一些帮助。过去几天我一直盯着我的电脑，想要自己解决这个问题。但我没有运气。

            string path = "c:\\" + textBox269.Text + "_" + id + ".wav";

            //Add recording to the listview
            item = new ListViewItem(textBox269.Text);
            item.SubItems.Add(richTextBox11.Text);
            item.SubItems.Add(DateTime.Now.ToString());
            item.SubItems.Add(path);
            listView1.Items.Add(item);

            System.Data.OleDb.OleDbCommandBuilder cb;
            cb = new System.Data.OleDb.OleDbCommandBuilder(rAD);

            DataRow rRow2 = rDS.Tables["Recordings"].NewRow();

            rRow2[1] = id;
            rRow2[2] = textBox269.Text;
            rRow2[3] = richTextBox11.Text;
            rRow2[4] = DateTime.Now.ToString();
            rRow2[5] = path;

            //rRow2["RefID"] = id;
            //rRow2["RecName"] = textBox269.Text;
            //rRow2["Desc"] = richTextBox11.Text;
            //rRow2["DateAdded"] = DateTime.Now.ToString();
            //rRow2["FileLocation"] = path;

            rDS.Tables["Recordings"].Rows.Add(rRow2);

            rMaxRows = rMaxRows + 1;
            rInc = rInc + 1;

            rAD.Update(rDS, "Recordings"); <--this line is where the error occurs

Answer 1

替换

rAD.Update(rDS, "Recordings");

用这个：

rAD.Update(rDS.Tables["Recordings"]);

Answer 2

要在ms-access中插入行，请尝试调整以下代码以满足您的需求：

public void InsertRow()
{
  try
  {
    using (OleDbConnection con = new OleDbConnection())
    {
      con.ConnectionString =  Users.GetConnectionString(); // your ms-access connection string
      con.Open();
      OleDbCommand cmd = new OleDbCommand();
      cmd.Connection = con;
      cmd.CommandType = CommandType.Text;
      cmd.CommandText = "INSERT INTO Recordings(RecName,Desc,DateAdded, FileLocation) VALUES(id,textBox269.Text,richTextBox11.Text,DateTime.Now,path)";
      cmd.ExecuteNonQuery();
    }
  }
  catch (Exception ex)
  {
    throw new Exception(ex.Message);
  }
}

INSERT INTO语句中的语法错误。谁能帮我这个？
