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

public:
 property bool IsReadOnly { bool get(); };
public bool IsReadOnly { get; }
member this.IsReadOnly : bool
Public ReadOnly Property IsReadOnly As Boolean

Property Value

Boolean

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

Remarks

A collection that is read-only does not allow the addition or removal of elements after the collection is created. Note that read-only in this context does not indicate whether individual elements of the collection can be modified, since the ICollection interface only supports addition and removal operations. For example, the IsReadOnly property of an array that is cast or converted to an ICollection object returns true, even though individual array elements can be modified.
