c# - 连接字符串 - Oracle

Question

我需要使用 C# 连接 Oracle 服务器。 这是字符串的参数。

服务器:dbs.cs.hacettepe.edu.tr 端口:1521 sid: ORAVT

这些的连接字符串是什么？我尝试了很多连接方式，但我无法处理它。顺便说一句，我使用的是 ODP.NET。

感谢您的帮助。

网络配置

    <configuration>
        <appSettings>
            <add key="connectionString" value="Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=dbs.cs.hacettepe.edu.tr)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=ORAVT))); User Id=YOUR_USER_HERE; Password=YOUR_PASS_HERE;"/>
        </appSettings>
    </configuration>

                return new OracleConnection(connection);
