Gets the time-out interval of the current instance.
Assemblies: System.Text.RegularExpressions (in System.Text.RegularExpressions.dll)
System (in System.dll)
The property defines the approximate maximum time interval for a Regex instance to execute a single matching operation before the operation times out. The regular expression engine throws a RegexMatchTimeoutException exception during its next timing check after the time-out interval has elapsed. This prevents the regular expression engine from processing input strings that require excessive backtracking. For more information, see Backtracking in Regular Expressions and Best Practices for Regular Expressions in the .NET Framework.
This property is read-only. You can set its value explicitly for an individual Regex object by calling the Regex.Regex(String, RegexOptions, TimeSpan) constructor; and you can set its value for all Regex matching operations in an application domain by calling the AppDomain.SetData method and providing a value for the "REGEX_DEFAULT_MATCH_TIMEOUT" property. If you do not explicitly set a time-out interval, the default value Regex.InfiniteMatchTimeout is used, and matching operations do not time out.
