ImmutableList<T>.ToBuilder Method

Definition

Creates a list that has the same contents as this list and can be efficiently mutated across multiple operations using standard mutable interfaces.

public System.Collections.Immutable.ImmutableList<T>.Builder ToBuilder ();

Returns

The created list with the same contents as this list.

Remarks

This is an O(1) operation and results in only a single (small) memory allocation. The mutable list that is returned is not thread-safe.
