Reader
|
Represents a fast, lightweight reader/writer lock that uses spinning to perform locking. No recursive acquires or
upgradable locks are allowed (i.e., all entered locks must be exited before entering another lock).

Methods| Name | Description | |
|---|---|---|
| EnterReadLock | Enters the lock in read mode. |
| EnterWriteLock | Enters the lock in write mode. |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| ExitReadLock | Exits read mode. |
| ExitWriteLock | Exits write mode. |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
Extension Methods| Name | Description | |

Remarks
This reader/writer lock uses SpinWait to spin the CPU instead of engaging event based locking. As a result it
should only be used in cases where lock times are expected to be very small, reads are very frequent and writes are rare.
If hold times for write locks can be lengthy, it will be better to use ReaderWriterLockSlim instead to avoid
unnecessary CPU utilization due to spinning incurred by waiting reads.
