Question

command.ExecuteNonQuery();前面的connection,和sql语句都定义好了，可是怎么还报错哦，代码如下:

using System;using System.Collections.Generic;using System.Linq;
using System.Text.RegularExpressions;
using System.Reflection;
using System.Text;using System.Data.OleDb;using System.Data.OracleClient; using System.DataSystem.Data.OracleClient.OracleCommand;
namespace ConsoleApplication2{ class jlxy { static void Main(string[] args) { string connStr = "Data Source=pbex;Persist Security Info=True;User ID=pbex;Password=pbex;Unicode=True"; string sqlstr = "insert into jlxiaxin values( 'c',22);";

using (OracleConnection conn = new OracleConnection(connStr)) { OracleCommand command = new OracleCommand(sqlstr, conn); command.Connection.Open(); command.ExecuteNonQuery(); }}

Answer 1

OracleCommand command = new OracleCommand(sqlstr, conn); command.Connection.Open(); 错误应该在这里,应该是,conn.Open(command);

Answer 2

把具体报错的信息发上来看下。
