异常：ORA-01036: 非法的变量名/编号

代码

C# code

private string DoInsert(HttpContext context)        {            string result = "";            string name=context.Request.Params["name"];            string parentid = context.Request.Params["parentid"];            if (name != null && parentid != null)            {                OracleConnection conn = new OracleConnection("Data Source=wgyx;user=wgyx;password=wgyx;");                OracleCommand cmd = new OracleCommand("INSERT INTO newclass ( cName, parentid ) VALUES(name,parentid)", conn);                cmd.Parameters.AddWithValue("name", name);                cmd.Parameters.AddWithValue("parentid", int.Parse(parentid));                try                {                    conn.Open();                    cmd.ExecuteNonQuery();                    conn.Close();                    cmd.CommandText = "Select max(id) from newclass";                    cmd.Parameters.Clear();                    conn.Open();                    result = cmd.ExecuteScalar().ToString();                    conn.Close();                }                catch (Exception ex)                {                    result = "-1";                }                finally                {                    conn.Close();                }            }            else            {                result = "-1";            }            return result;        }

不知道上面的代码哪里出错了？

[解决办法]
int.Parse(parentid) 改
Convert.ToInt32(parentid)
[解决办法]
values里面改为values(@name,@parentid)试试
