#### Thread Safety

This type is not safe for multithreaded operations.

#### Remarks

`ReaderWriterLock` 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 `ReaderWriterLock` provides better throughput than a simple one-at-a-time lock, such as Monitor.

If a platform does not support a `System.Threading.ReaderWriterLock` implementation then all readers and writers are serialized. Therefore the caller must not rely on multiple simultaneous readers.

#### Requirements

Namespace: log4net.Util

Assembly: log4net (in log4net.dll)
