ICollection<'T>.IsReadOnly Property
.NET Framework (current version)
Gets a value indicating whether the ICollection<'T> is read-only.
Assembly: mscorlib (in mscorlib.dll)
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<'T> interface only supports addition and removal operations. For example, the IsReadOnly property of an array that is cast or converted to an ICollection<'T> object returns true, even though individual array elements can be modified.
