C#中如何用comBox控件被点击后所对应的项查找数据库后输出相应的值？？

控件代码如下

    private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
    {
        sqlcon = new SqlConnection(strcon);
        sqlcon.Open();
        SqlCommand sqlcmd = new SqlCommand();
        sqlcmd.Connection = sqlcon;
        string name = "";
        name = comboBox1.Text.ToString();
        Console.WriteLine(comboBox1.Text.ToString());
        sqlcmd.CommandText = "select Money from nini where Name = " + name.ToString(). Trim();
        sqlcmd.CommandType = CommandType.Text;
        SqlDataReader reader = sqlcmd.ExecuteReader();
        while (reader.Read())
        {
            listView1.Items.Add(reader[0].ToString());
            textBox1.Text = reader[0].ToString();
        }
    }

你的那个列名值在SQL语句里没有用单引号括住

sqlcmd.CommandText = "select Money from nini where Name = '" + name.ToString(). Trim()+"'";
