C#调用oracle存储过程最简单的实例
　　Oracle方面
１．创建Oracle过程存储
create or replace procedure proce_test(paramin in varchar2,paramout out varchar2,paraminout in out varchar2)
as
varparam varchar2(28);
begin
varparam:=paramin;
paramout:=varparam|| paraminout;
end;
２．测试过程存储
declare
param_out varchar2(28);
param_inout varchar2(28);
begin
param_inout:='ff';  
proce_test('dd',param_out,param_inout);  
dbms_output.put_line(param_out);
end;
　　C#方面
引用Oracle组件
 

using System;

using System.Data;

using System.Data.OracleClient;  

 

namespace WebApplication4

{

     public class OraOprater

     {

         private OracleConnection conn=null;

         private OracleCommand cmd=null;

         public OraOprater()

         {

             //连接数据库

              string mConn="data source=ora9i.ora.com;user id=ora;password=ora";

              conn=new OracleConnection(mConn);

              try

              {

                   conn.Open();

                   cmd=new OracleCommand();

                   cmd.Connection=conn;

              }

              catch(Exception e)

              {

                   throw e;

              }

         }

 

         public string SpExeFor(string m_A,string m_B)

         {

                //存储过程的参数声明

              OracleParameter[] parameters={

                new OracleParameter("paramin",OracleType.VarChar,20),

                new OracleParameter("paramout",OracleType.VarChar,20),

                new OracleParameter("paraminout",OracleType.VarChar,20)

                                                };

              parameters[0].Value=m_A;

              parameters[2].Value=m_B;

              parameters[0].Direction=ParameterDirection.Input;

              parameters[1].Direction=ParameterDirection.Output;

              parameters[2].Direction=ParameterDirection.InputOutput;

              try

              {

                   RunProcedure("proce_test",parameters);

                  return parameters[1].Value.ToString();

              }

              catch(Exception e)

              {

                   throw e;

              }

         }

 

         private void RunProcedure(string storedProcName,OracleParameter[] parameters)

         {

              cmd.CommandText=storedProcName;//声明存储过程名

              cmd.CommandType=CommandType.StoredProcedure;

              foreach(OracleParameter parameter in parameters)

              {

                   cmd.Parameters.Add(parameter);

              }

              cmd.ExecuteNonQuery();//执行存储过程

         }

     }

}
