1.
发布时需要包括下面的dll
http://www.189works.com/article-58367-1.html
或者下载oracle ODAC 的xcopy版，运行install.bat all c:\oracle odac 进行安装

2.
可以使用EF,参数化查询时使用:paramName

View Code

        private void button4_Click(object sender, EventArgs e)

        {

            var cmdText=@"select e.empno, e.ename, e.hiredate, d.dname from scott.emp e inner join scott.dept d

                         on e.deptno=d.deptno 

                         where d.deptno=:deptno";

            var ctx = new Entities();

            var list= ctx.ExecuteStoreQuery<EmpInfo>(cmdText,20).ToList();

        }

    }





    public class EmpInfo

    {

        public int EMPNO { get; set; }

        public string EName { get; set; }

        public DateTime HireDate { get; set; }

        public string DName { get; set; }

    }

3.
连接可以这么写:
string connstring = "Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.30)(PORT=1521)) (CONNECT_DATA=(SID=ORCL)));User Id=scott;Password=password;"
也可以这样:
string connstring = "Data Source=192.168.1.30:1521/ORCL;User Id=scott;Password=password;"
以管里员身份登录:
 string connstring = "Data Source=192.168.1.30:1521/ORCL;User Id=Sys;Password=admin;DBA Privilege=SYSDBA;";

4.
使用 Oracle Net Configuration Assistant 可以配置Oracle连接端口，老连不上的话，可以用这个试试
