正则表达式匹配不起作用

Question

If the result is not a success the Compiler ist just stopping and debug is also just stopping but there is no error, it's just stopping. If the Result is a success it works but the else part is not working but what can i do if the compiler is just stopping if the Result is a not success?

Match Result = Regex.Match(file, pattern);

if(Result.Success)
{
    // This part works
}
else
{
    // this is not working
}

There is a try catch arround this, just to mention it.

Answer 1

else block is only executed if the if block fails. In your case the regex is successfully matching so your else{ } isn't executed.

Don't worry if it doesn't match. If regex doesn't match, it will return false and your else{ } will be executed.

Answer 2

I don't think the problem lies in the fact that Success is true or false. I tried this code and it works:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;

namespace RegexTest
{
    class Program
    {
        static void Main(string[] args)
        {
            string s1, s2, s0;
            //Regex regex;
            Match match;
            s0 = "l'insostenibile leggerezza dell'essere";
            s1 = "g.+z";
            s2 = "'.*'";
            try
            {
                match = Regex.Match(s0, s1);
                if(match.Success)
                {
                }
                else
                {
                }
                match = Regex.Match(s0, s2);
                if(match.Success)
                {
                }
                else
                {
                }
                s1 = "x.+r";
                match = Regex.Match(s0, s1);
                if(match.Success)
                {
                }
                else
                {
                }
            }
            catch(Exception ex)
            {
            }

        }
    }
}

Have you checked the clause? Replace your clause in my code and try again.
