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 cannot be read, the method returns a specified default value.
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 cannot be read, 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 to return if the file cannot be read. The method will attempt to deserialize the JSON content into an object of type T.
Ensure that the JSON structure in the file matches the structure of the type T to avoid deserialization errors.
// Example usage of ReadJson<T> method
var fileSystem = new BaseFileSystem();
string filename = "config.json";
MyConfig defaultConfig = new MyConfig();
// Attempt to read and deserialize the JSON file into a MyConfig object
MyConfig config = fileSystem.ReadJson<MyConfig>(filename, defaultConfig);
// Use the config object
if (config != null)
{
// Access properties of the config object
Console.WriteLine(config.SomeProperty);
}
