为什么数据库可以连接上,却写不进数据库东西啊

UUxin ()

代码如下.
谢谢帮忙看下啊
    protected void Page_Load(object sender, EventArgs e)
    {
        String StrConn = "provider=Microsoft.Jet.OLEDB.4.0;data source='" + Server.MapPath(ConfigurationManager.AppSettings["dns"]) + "'";
        //连接本地数据库
        Conn = new OleDbConnection(StrConn);
        //Response.Write(Conn.State);
    }
    protected void post_Click(object sender, EventArgs e)
    {
        Conn.Open();
        Comm = new OleDbCommand("insert into User (Uname) values ('"+Convert.ToString(Uname.Text.Trim())+"')", Conn);
        //Comm.ExecuteNonQuery();
        Comm.Dispose();
        Conn.Close();
        Response.Write("");
        Label3.Text = Uname.Text + "ok";
        Response.Write(Uname.Text);
    }
}

Comm = new OleDbCommand("insert into User (Uname) values ('"+Convert.ToString(Uname.Text.Trim())+"')", Conn);
USER这个表名应该用中括号括起来，改成：
Comm = new OleDbCommand("insert into [User] (Uname) values ('"+Convert.ToString(Uname.Text.Trim())+"')", Conn);
