| <P>Public static (<b>Shared</b> in Visual Basic) members of this type are |
| safe for multithreaded operations. Instance members are <b>not</b> guaranteed to be |
| thread-safe.</P> |
| <h4 class="dtH4">Remarks</h4> |
| <p> |
| <code>ReaderWriterLock</code> is used to synchronize access to a resource. At any given time, it allows either concurrent read access for multiple threads, or write access for a single thread. In a situation where a resource is changed infrequently, a <code>ReaderWriterLock</code> provides better throughput than a simple one-at-a-time lock, such as <a href="ms-help://MS.NETFrameworkSDKv1.1/cpref/html/frlrfSystemThreadingMonitorClassTopic.htm">Monitor</a>. </p> |
| <p> If a platform does not support a <code>System.Threading.ReaderWriterLock</code> implementation then all readers and writers are serialized. Therefore the caller must not rely on multiple simultaneous readers. </p> |
