通过 ADO.NET 连接到 Oracle DB 出现问题

Question

我的连接字符串

string connectionString = @"User Id = id; Password = pass; Data Source = (DESCRIPTION =
          (ADDRESS_LIST =
           (ADDRESS = (PROTOCOL = TCP)(HOST = xx.xx.xx.x)(PORT = 1521))
          )
        (CONNECT_DATA =
             (SERVICE_NAME = name)
          )
         )";

如果我使用 OracleConnection

using (OracleConnection connection = new OracleConnection(connectionString))
{
    connection.Open();
}

我收到以下错误

System.Exception：'OCIEnvCreate 失败，返回码 -1，但错误消息文本不可用。'

Answer 1

您可以使用简单的连接字符串，例如

 string connectionString="Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=DEMO)));User Id =USERNAME;  Password =PASSWORD; ";

然后只需创建新连接：

OracleConnection con = new OracleConnection();
con.ConnectionString = connectionString;
con.Open();

这也对你有用。
