.net - How to make ConfigurationManager read a config file other than app.config?

Question

I need to parse a config file that is situated in another project. I know that ConfigurationManager reads the app.config file by default, but how to make it read that particular config file?

Answer 1

// Create a filemap refering the config file.
ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
fileMap.ExeConfigFilename = configFilePath;

// Retrieve the config file.
Configuration configuration = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);

Answer 2

或者像这样：

var fileMap = new ConfigurationFileMap(configFilePath);
Configuration config = ConfigurationManager.OpenMappedMachineConfiguration(fileMap);

但是您仍然会遇到自定义配置部分的问题。
