Question

I’m trying to make a genric code to serialize and deserialize any object that implement a specific interface. The problem is that I need to create an instance of an object before I can call the .Deserialize() because you can’t use a static function in an interface. Now my Question is how do I make an instance of T ? or is there a better way to achieve my goal ?

public static class Serializer
{
    public static byte[] Serialize<T>(T Obj) where T : Data;
    public static T Deserialize<T>(byte[] Data) where T : Data
    {
        //Here I need to something like:  new T().Deserialize(Data);
    }
}
public interface Data
{
    public byte[] Serialize<T>(T obj);
    public T Deserialize<T>(byte[] Data);

}
class Program
{
    static void Main(string[] args)
    {
        Serializer.Deserialize<Dummy>(new byte[20]);
    }
}
class Dummy : Data
{

}

Update
Fixed the code/typos

Use the new() keyword

public interface IData
{
    public byte[] Serialize<T>(T obj);
    public T Deserialize<T>(byte[] Data);
}
public static class Serializer
{
    public static byte[] Serialize<T>(T Obj) where T : IData;
    public static T Deserialize<T>(byte[] data) where T : IData, new()
    {
        T res=new T();
        res.Deserialize<T>(data);
        return res;
    }
}
class Program
{
    static void Main(string[] args)
    {
        Serializer.Deserialize<Dummy>(new byte[20]);
    }
}
class Dummy : IData
{

}
