如何对ConnectionString进行加密解码？

这个就不说了就是一个类

    public static class EncryptionConfig

    {

        /*  加密配置节点

         *  Response.Write(EncryptionConfig.Encryption("connectionStrings"));

         *  解密配置节点

         *  Response.Write(EncryptionConfig.Deciphering("connectionStrings"));

         *  不影响读取

            Response.Write(WebConfigurationManager.AppSettings[0].ToString());

            Response.Write(WebConfigurationManager.AppSettings[1].ToString());

         */
