Gets a value indicating whether access to the ICollection is synchronized (thread safe).
Assembly: mscorlib (in mscorlib.dll)
private abstract IsSynchronized : bool with get private override IsSynchronized : bool with get
Property ValueType: System.Boolean
true if access to the ICollection is synchronized (thread safe); otherwise, false. In the default implementation of List(T), this property always returns false.
Default implementations of collections in the System.Collections.Generic namespace are not synchronized.
Enumerating through a collection is intrinsically not a thread-safe procedure. In the rare case where enumeration contends with write accesses, you can lock the collection during the entire enumeration. To allow the collection to be accessed by multiple threads for reading and writing, you must implement your own synchronization.
Retrieving the value of this property is an O(1) operation.
