The ReadJsonOrDefault<T> method attempts to read a JSON file and deserialize its contents into an object of type T. If the file cannot be read or deserialized, the method returns a specified default value.
The ReadJsonOrDefault<T> method attempts to read a JSON file and deserialize its contents into an object of type T. If the file cannot be read or deserialized, the method returns a specified default value.
Use this method when you want to safely attempt to read and deserialize a JSON file, and have a fallback value in case of failure. This is particularly useful for configuration files or data files where a default state is acceptable if the file is missing or corrupted.
// Example usage of ReadJsonOrDefault var fileSystem = new BaseFileSystem(); string filename = "config.json"; MyConfig defaultConfig = new MyConfig(); // Attempt to read the JSON file, or use the defaultConfig if an error occurs MyConfig config = fileSystem.ReadJsonOrDefault<MyConfig>(filename, defaultConfig); // Use the config object Console.WriteLine(config.SomeSetting);
