從.net訪問oracle數據庫時獲取解決方案c＃

我有一個使用System.Data.OracleClient訪問oracle數據庫的C＃程序。從.net訪問oracle數據庫時獲取解決方案c＃

該代碼使用OracleCommand，Dataset對象。

命令結構如下

con = new OracleConnection(conStr); 
con.Open(); 
OracleDataAdapter adp = new OracleDataAdapter("select * from sample", con); 
DataSet ds = new DataSet(); 
adp.Fill(ds); 
DataTable dt = ds.Tables[0]; 
con.Close();

和初始化值作爲

public static String conStr = "SERVER=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=******)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=******)));uid=#####;pwd=#######;"; 
private OracleConnection con; 
private String query; 
private OracleCommand cmd; 
private OracleDataReader rd;

和

我得到誤差作爲

堆棧跟蹤：

目標站點：

{Void .ctor(System.Data.OracleClient.OciHandle, HTYPE, MODE, HANDLEFLAG)}

消息：

OCIEnvCreate failed with return code -1 but error message text was not available.

我不知道啊，我被困在

我使用Oracle 10g和DOTNET 2010

等待您的寶貴回覆和評論......
