I am having issues when attempting to use the following regular expression:
string profileConfig = File.ReadAllText(str);
string startIndex = "user_pref(\"network.proxy.autoconfig_url\", \"";
string endIndex = "\"";
var regex = startIndex + "(.*)" + endIndex;
// Here we call Regex.Match.
Match match = Regex.Match(profileConfig,
regex,
RegexOptions.IgnoreCase);
// Here we check the Match instance.
if (match.Success)
{
// Finally, we get the Group value and display it.
string key = match.Groups[1].Value;
MessageBox.Show(key);
}
I get the error:
Additional information: parsing "user_pref("network.proxy.autoconfig_url", "(.*)"" - Not enough )'s.
Is my regular expression malformed in some way?
如果您打算匹配字符,请转义第一个括号(
字面意思是:
string startIndex = "user_pref\\(\"network.proxy.autoconfig_url\", \"";
Correct this:
"user_pref(\"network. -> "user_pref\(\"network.
