Regex.CacheSize Property

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

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

Namespace:  System.Text.RegularExpressions
Assembly:  System (in System.dll)

'Declaration
Public Shared Property CacheSize As Integer

Property Value

Type: System.Int32
The maximum number of entries in the static cache.

ExceptionCondition
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 regular expressions. Your application typically will not need to modify the size of the cache. Use the CacheSize property in the rare situation when you need to turn off caching or you have an unusually large cache.

Version Notes

Windows Phone

 In Windows Phone, the CacheSize property always returns zero because the Regex class implementation does not support caching.
