Assembly: System (in System.dll)
| Exception | Condition |
|---|---|
| ArgumentOutOfRangeException | The value in a set operation is less than zero. |
The Regex class maintains an internal cache of compiled regular expressions used in static method calls. If the value specified in a set operation is less than the current cache size, cache entries are discarded until the cache size is equal to the specified value.
By default, the cache holds 15 compiled static regular expressions. Your application typically will not have to modify the size of the cache. Use the CacheSize property only when you want to turn off caching or when you have an unusually large cache.
Notes to CallersIn the .NET Framework prior to the .NET Framework 2.0 SP1, regular expressions used in both static and instance method calls were cached. Beginning with the .NET Framework 2.0 SP1, only regular expressions used in static method calls are cached.
