在 C# 中更新配置文件

Question

我正在为我的公司系统创建一个更新，它将在多个客户端上运行，我有两个配置文件，旧配置文件和新版本。 有什么方法可以比较这两个文件并检查差异以将我在第一个文件中的新内容添加到旧文件中？ 请记住，文件可能有不同的信息，我唯一需要添加/更改的是密钥。例如，如果密钥不同，则将旧的密钥更改为新的“版本”，如果旧文件中不存在密钥，则添加它。

它们的键名完全相同，但值可能不同。另外可能有一个旧文件中不存在的新密钥，我需要添加它

我将留下一个文件示例供您查看，

任何帮助将不胜感激。

代码是这样的，它就像一个魅力：

public void UpdateService(string FilePathOld, string FilePathNew, string LatestVersion)
{
        Dictionary<string, string> Old = new Dictionary<string, string>();
        Dictionary<string, string> New = new Dictionary<string, string>();

        if (ExisteFicheiro(FilePathNew) == true && ExisteFicheiro(FilePathOld) == true)
        {
            ExeConfigurationFileMap configOld = new ExeConfigurationFileMap();
            configOld.ExeConfigFilename = FilePathOld;
            Configuration config = ConfigurationManager.OpenMappedExeConfiguration(configOld, ConfigurationUserLevel.None);

            ExeConfigurationFileMap configNew = new ExeConfigurationFileMap();
            configNew.ExeConfigFilename = FilePathNew;
            Configuration config2 = ConfigurationManager.OpenMappedExeConfiguration(configNew, ConfigurationUserLevel.None);

            KeyValueConfigurationCollection settings = config.AppSettings.Settings;
            Old = settings.AllKeys.ToDictionary(key => key, key => settings[key].Value);
            KeyValueConfigurationCollection settings2 = config2.AppSettings.Settings;
            New = settings2.AllKeys.ToDictionary(key => key, key => settings2[key].Value);

            foreach (var NewKey in New)
            {
                string value;
                if (Old.TryGetValue(NewKey.Key, out value))
                {
                    if (value != NewKey.Value)
                    {
                        //if (ExistsKey(NewKey.Key, false) == true)
                        Old[NewKey.Key] = NewKey.Value;

                    }
                }
                else
                {
                    Old.Add(NewKey.Key, NewKey.Value);
                }
            }

            foreach (var NewKey in Old)
            {
                string key = NewKey.Key;
                string value = NewKey.Value;
                if (config.AppSettings.Settings[key] != null)
                {
                    config.AppSettings.Settings[key].Value = value;
                    if (key == "Version")
                        config.AppSettings.Settings[key].Value = LatestVersion;
                }
                else
                {
                    config.AppSettings.Settings.Add(key, value);

                }
                if (config.AppSettings.Settings["Version"] == null)
                {
                    config.AppSettings.Settings.Add("Version", LatestVersion);
                }

            }
            config.Save();
        }
        else
        {
            Erro NovoErro = new Erro();
            Global.Erro = "O ficheiro \"OrcaService.exe.config\" ou o ficheiro \"Orca.exe.config\" não existem nos caminhos especificados!";
        }

}
