Deserialize File Variables In A Custom Extension File? (C#)

Question

I Need To storage variables In a File with Custom Extension And Open That variables In my app

Answer 1

Add a [Serializable] attribute to the class being serialized.

[Serializeable]
public class NiceClass
{
}

Make a Serialize method and a Deserialize method

public void SerializeObject<T>(string filename, T obj)
{
Stream stream = File.Open(filename, FileMode.Create);
BinaryFormatter binaryFormatter = new BinaryFormatter();
binaryFormatter.Serialize(stream, obj);
stream.Close();
}

public T DeSerializeObject<T>(string filename)
{
T objectToBeSerialized;
Stream stream = File.Open(filename, FileMode.Open);
BinaryFormatter binaryFormatter = new BinaryFormatter();
objectToBeSerialized = (T)binaryFormatter.Deserialize(stream);
return objectToBeSerialized;
}

I use a binaryFormatter but you can also use a XmlFormatter
