如果我正确理解你的问题，我不会尝试存储连接以供以后重用。相反，我会让连接池来处理缓存连接对象。请查看 Oracle Data Provider for .NET的功能 [ ^ ]



连接字符串本身的内容，您可以存储它以便快速访问，例如在配置文件中，在单个静态字符串变量等中。



例如，看看在C＃中读取配置设置的四种方法 [ ^ ]

If I understand your question correctly, I wouldn't try to store the connection for later reuse. Instead I would let connection pooling to take care of caching the connection objects. Have a look at Features of Oracle Data Provider for .NET[^]

What comes to the connection string itself, you can store it for quick access for example in a configuration file, in a single, static string variable etc.

For example, have a look at Four Ways to Read Configuration Setting in C#[^]
