是否有可能在.NET（C＃）中以编程方式从头创建* .config文件？

Question

For our approach we want to create one of the *.config files from scratch and populate it with some default/custom values at runtime.

Is there possibility to do this programatically via ConfigurationManager or something like that?

Answer 1

Yes. As you point out, the ConfigurationManager class allows you to read and write config files.

ConfigurationManager Class

Scroll down a bit.

Sure, you can read / write these files as XML files, but the above class exposes a much handier interface for manipulating config files.

To trick the ConfigurationManager into opening an arbitrarily named config file, you can [ab?]use ExeConfigurationFileMap . Note that file may not exist, in which case it will be created when you call Save()

ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap
{
    ExeConfigFilename = file
};
var config = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);
//todo manipulate config. add settings / connection strings etc.
config.Save();

Answer 2

由于.config文件只是XML，因此您应该只需使用XmlTextWriter来构建配置文件。

Answer 3

sure it is, it's a simple and plain xml file

now... what config file are you writing about? app.config ? web.config ? custom.config ?

first two are configuration support for the windows app and web app , so you would need to generate from an " outside " app and then fire that app up (witch that already happens with the Setup project where it asks for the user things and you can edit/add to the configuration file, like Database connections, etc)
