c#连接ORACLE报错ORA-12154: TNS: 无法处理服务名

[qq_39481637]

string ConnectionString = "Data Source=ORCL; User Id=sjwj; Password=sjwj";  //连接字符串          
            OracleConnection conn = new OracleConnection(ConnectionString);    //创建一个新连接                
            try {                 
                conn.Open();    //打开连接              
               
            }
            catch (Exception ex)
            {

                MessageBox.Show(ex.Message.ToString());
            }
            finally
            {
                conn.Close();
            }

连不上
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
连接串也配置好了 PLsql能连上 就C#连接ORACLE连不上

直接搜索关键字“ORA-12154 无法处理服务名”，结果帖子里检测方法都尝试下

[mirrorspace]

不用微软自带的那个了,用ORACLE提供的这个 Oracle.ManagedDataAccess.dll
