推荐答案

如果这是将配置和一台计算机（在多台计算机共享）您的应用程序实例上使用的connectionString，您可以使用.NET托管的DPAPI（数据保护API）的包装 - 的的 ProtectedData类（System.Security.Cryptography）。

If this is a connectionString that will be configured and used on a single computer (not shared across multiple computers) by an instance of your application, you can use the .NET managed wrapper of the DPAPI (Data Protection API) - the ProtectedData class (System.Security.Cryptography).

有一个巧妙的方法，你也可以使用（如果你决定使用这个类）是创造编码和解码字符串扩展方法，使操作变得简单：

A neat trick you could also use (should you decide to use this class) is to create extension methods for Encoding and Decoding a string, so the operations become as simple as:

string encodedString = myConnectionString.EncodeString();

string decodedString = encodedString.DecodeString();

希望这有助于！
