TimephasedDataCollection.IsReadOnly

TimephasedDataCollection.IsReadOnly property

Gets a value indicating whether the ICollection is read-only.

public bool IsReadOnly { get; }

Return Value

true if the ICollection is read-only; otherwise, false.

Examples

Shows how to work with timephased data collections.
