public static readonly TimeSpan InfiniteMatchTimeout;

 staticval mutable InfiniteMatchTimeout : TimeSpan

Public Shared ReadOnly InfiniteMatchTimeout As TimeSpan 

Field Value

TimeSpan

Remarks

The Regex(String, RegexOptions, TimeSpan) class constructor and a number of static matching methods use the InfiniteMatchTimeout constant to indicate that the attempt to find a pattern match should not time out.

Warning

Setting the regular expression engine's time-out value to InfiniteMatchTimeout can cause regular expressions that rely on excessive backtracking to appear to stop responding when processing text that nearly matches the regular expression pattern. If you disable time-outs, you should ensure that your regular expression does not rely on excessive backtracking and that it handles text that nearly matches the regular expression pattern.

For more information about handling backtracking, see Backtracking.

The InfiniteMatchTimeout constant can be supplied as the value of the matchTimeout argument of the following members:

• Regex(String, RegexOptions, TimeSpan)

• Match(String, String, RegexOptions, TimeSpan)

• Matches(String, String, RegexOptions, TimeSpan)

• Replace(String, String, String, RegexOptions, TimeSpan)
