Method regexp.escapeQE

---

Overload

Encloses string in \Q\E if it contains metacharacters \^$.[|()?*+{ or if always == true.

public static string escapeQE(string s, bool always = false)

Parameters

s  (string) Can be null.

always  (bool) Enclose always, even if the string does not contain metacharacters. Should be true if the regular expression in which this string will be used has option "extended", because then whitespace is ignored and # is a special character too.

Returns

string

Remarks

Such enclosed substring in a regular expression is interpreted as a literal string. This function also escapes \E, so that it does not end the literal string.
