Can you use “where” to require an attribute in c#?

public class MyClass<T> where T : //[is serializable/has the serializable attribute]

public void Initialize<T>(T obj)
{
     object[] attributes = obj.GetType().GetCustomAttributes(typeof(SerializableAttribute));
     if(attributes == null || attributes.Length == 0)
          throw new InvalidOperationException("The provided object is not serializable");
}
