在C＃中更新配置文件 [英] Updating a config file in c#
问题描述
我正在为公司系统创建一个更新，该更新将在多个客户端上运行，并且我有两个配置文件，旧的配置文件和较新的版本。
有什么方法可以比较两个文件并检查差异，以将第一个文件中的新内容添加到旧文件中？
请记住，文件可能具有不同的信息，我唯一需要添加/更改的是密钥。例如，如果密钥不同，则将旧密钥更改为新的版本，如果旧文件中不存在密钥，则将其添加。
I am creating an update to my companies system that will be running on several clients and I have two config files, the old config file and the newer version. Is there any way that I can compare the both files and check the differences to add to the older file what I have new in the first one? Keep in mind that the files may have different info and the only thing that I need to add/change is the keys. For example, if a key is different change the older to that new "version", if a key doesn’t exist in the older files add it.
它们的密钥将具有完全相同的名称，但可能具有不同的值。加上旧文件中可能不存在新密钥，我需要添加它
they keys will have the exact same name but may have different values. Plus there could be a new key that doesnt exist in the older file and I need to add it
我将为您提供示例文件，供您查看，
I will leave an example of the files for you to see,
任何帮助将不胜感激。

推荐答案
代码就像这样，它就像一个符咒：
Code went like this and it works like a charm:
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!";
}
}
