match in the input string. This is one of the most common methods we use when using C # regular expressions. The following example illustrates the use of the IsMatch method:if (!objalphapatt.ismatch ("Testismatchmethod"))Lblmsg.text = "Match succeeded";ElseLblmsg.text = "Match not successful";The result of this code execution is "match succeeded"if (! Objalphapatt.ismatch ("testisMatchMethod7654298"))Lblmsg.text = "Match succeeded";ElseLblmsg.text =

C # provides a very powerful function for the use of regular expressions, which is the Regex class. This package is included under the System.Text.RegularExpressions namespace, and the DLL where the namespace is located basically does not need to be added separately in all project templates and can be used directly.1.

RegEx library Installation Summary
After learning regular expressions, I am eager to implement some functions through programming. I learned from the Internet that the boost. RegEx Library provides what I want. It is no exaggeration to say that I have been happy for several days because I know the boost library...
So, to get started, you have to do some trouble to use the boost library instead of an include
, ExceptionUsing try or throw throws exception catch handling exceptions, some exceptions can do nothing, like endofstreamexception. Exceptions are not vulnerabilities or errors, and handling of exceptions is important, and exceptions affect the performance of the program.try {Double A = 5; Double b = 0; Dodivide (A, b);}catch (System.DivideByZeroException){...}catch (System.ArithmeticException){...}catch (Exception e){...}Public double dodivide (double A, double b){if (b = = 0) {throw new Syste

First, in C #, to use the regular expression class, add the following statement at the beginning of the source file:using System.Text.RegularExpressions;Second, the Regex class commonly used methods1. Static Match methodUsing the static Match method, you can get a continuous substring of the first matching pattern in the source.the static Match method has 2 overloads, each of which isRegex.match (string inp
Let's just talk about the content.
Use RegEx. when using the match () method, you want to match a substring, but the content to be matched may contain line breaks in the resources I load, for example, if the content of my resource is John \ r \ n Smith, I want to match John Smith.
1. vertices (.) in a regular expression (.) represents all characters except \ n, but this is only used outside brackets ([]). If used in brackets, it only represents the do
The regular expression (regex), using Boost's regex header file, is the new standard for c++11, but gcc4.8.1 is not fully supported, so use boost library;

C # Regular Expression tutorial and example,
For a while, regular expression learning was very popular. At that time, I could see several regular expression posts in one day at CSDN, during that time, I learned some basic knowledge through the C # string and regular expression reference manual published by the Forum and Wrox Press, and earned about 1000 points in
