从MS Access数据库获取数据并将其显示在列表框中

Question

如何读取ms访问数据库中的数据并将其显示在列表框中.我这里有代码,但我有错误.

 private void button3_Click(object sender, EventArgs e)
    {
        using (OleDbConnection conn = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=\\Sisc-stronghold\mis!\wilbert.beltran\DataBase\DataStructure.accdb"))
        using(OleDbCommand cmd = new OleDbCommand(" SELECT * from TableAcct", conn))
        {
            conn.Open();
            OleDbDataReader Reader = cmd.ExecuteReader();
            //if (Reader.HasRows)
            if (Reader.HasRows)
            {
                Reader.Read();
                listBox1.Text = Reader.GetString("FirstName");
            }
        } 

错误在这里:1.错误1'System.Data.Common.DbDataReader.GetString(int)'的最佳重载方法匹配有一些无效的参数.2.错误2参数'1':无法从'string'转换为'int'

尝试这个,

       List<String> firstName = new List<String>();
       List<String> lastName = new List<String>();

       private void loadButton_Click(object sender, EventArgs e)
       {
                cn.Open();
                OleDbDataReader reader = null;
                cmd = new OleDbCommand("select* from Records", cn);
                reader = cmd.ExecuteReader();
                while (reader.Read())
                {
                    firstName.Add(reader["FirstName"].ToString());
                    lastName.Add(reader["LastName"].ToString());
                }
                cn.Close();
       }

然后在搜索按钮中插入,

private void searchButton_Click(object sender, EventArgs e)
        {
            clearSearchResult();
            try
            {
                int totalItems = FirstName.Count;
                int count = 0;
                while (count < totalItems)
                {
                    if (textBox6.Text == FirstName[count].ToString())
                    {
                        listBox1.Items.Add(FirstName[count].ToString());
                        count = 100;
                    }
                    else
                    {
                        count++;
                    }

这是很好的,当你想展示的信息使用"FirstName"的listBox1_SelectedIndexChanged,如果你想要的.这是一个例子,

private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
                int totalItems = lastName.Count;
                int count = 0;
                while (count < totalItems)
                {
                    if ((listBox1.SelectedItem.ToString()) == firstName[count].ToString()))
                    {
                        textBox1.Text = firstName[count].ToString();
                        textBox2.Text = lastName[count].ToString();
                        count = 100;
                    }
                    else
                    {
                        count++;
                    }
               }

希望这可以帮助,
