The ReadJson<T> method in the BaseFileSystem class is used to read a JSON file and deserialize its contents into an object of type T. If the file does not exist or an error occurs during deserialization, the method returns a specified default value.
To use the ReadJson<T> method, provide the filename of the JSON file you wish to read and a default value of type T that will be returned if the file cannot be read or deserialized.
This method is not static, so it must be called on an instance of BaseFileSystem.
// Example usage of ReadJson<T> method
var fileSystem = new BaseFileSystem();
string filename = "config.json";
MyConfig defaultConfig = new MyConfig();
// Attempt to read the JSON file and deserialize it into a MyConfig object
MyConfig config = fileSystem.ReadJson<MyConfig>(filename, defaultConfig);
// Use the config object
if (config != null)
{
// Process the configuration
}
