Gets or sets the maximum number of entries in the current static cache of compiled regular expressions.

public static int CacheSize { get; set; }
member this.CacheSize : int with get, set
Public Shared Property CacheSize As Integer

Property Value

The maximum number of entries in the static cache.



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 Callers

In 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.
