Skip Members

Attribute#

By default CloneBox copies every property and field it is allowed to see. Mark a member or a whole class with [DoNotClone] to leave it out:

• On CloneX() the member stays at its default on the clone.
• On CloneXTo() the destination keeps its current value.

public class User {
    public string Name { get; set; }
    [DoNotClone] public string Password { get; set; }
}

var clone = user.CloneX();
// clone.Name == user.Name, clone.Password == null

You can also put [DoNotClone] on a class so instances of that type are not cloned as nested objects.

Predicates#

When you cannot change the type — a third-party class, or a rule that spans many members — use predicates on CloneSettings:

var clone = source.CloneX(new CloneSettings {
    DoNotCloneProperty = p => p.Name == "Password" || p.Name == "Token",
    DoNotCloneField    = f => f.Name.StartsWith("_cache"),
    DoNotCloneClass    = t => t == typeof(Logger)
});

Attributes and predicates are combined: a member is skipped if either applies.
