急求解决:错误:Format of the initialization string does not conform to specification starting at index 0.

Question

请问各位大虾:
     我的Web应用程序调试时老是提示错误:Format of the initialization string does not conform to specification starting at index 0.
连接oracle数据库的字符串:
   string str_conn = "user id=aaa;pwd = aaa;data source=111;persist security info=False";
string str_sql = "select DOCID,DOCNAME,LOGIN,DOCNO,VERSION,CREATEDATE,SUBMITDATE from dmdocinfo";
OracleConnection OracleConnection2 = new OracleConnection("str_conn");
OracleDataAdapter OracleDataAdapter1 = new OracleDataAdapter(str_sql,OracleConnection2);
DataSet dataSet2 = new DataSet();
OracleDataAdapter1.Fill(dataSet2,"dmdocinfo");
oracleSjCommand.Connection = oracleConnection2;
oracleSjCommand.CommandText = "select DOCID,DOCNAME,LOGIN,DOCNO,VERSION,CREATEDATE,SUBMITDATE from dmdocinfo";
DataGrid DataGrid1 = new DataGrid();
DataGrid1.DataSource = dataSet2.Tables["dmdocinfo"].DefaultView;
DataGrid1.DataBind();
提示的错误行是 
OracleConnection OracleConnection2 = new OracleConnection("str_conn");请问到底是怎么回事啊?连接字符串str_conn没错啊?用VS2003自己生成一个连接字符串试了试,还是不行,求大虾赐教!!!!!!!!!!!!!!!

OracleConnection OracleConnection2 = new OracleConnection("str_conn");改成：OracleConnection OracleConnection2 = new OracleConnection(str_conn);
