本文关键字：路径系统文件夹正则表达式单个 FTP 用于文件夹验证程路径 | 更新日期: 2023-09-27 18:29:32

我想要一个Regex用于C#中的文件夹路径验证（远程路径、FTP路径、本地系统文件夹路径等）。

示例：

c:'folder one'folder2'folder 3
''remoteMachine'folder1
''1.22.33.444'folder 1'folder2
ftp://12.123.112.231/
C:'Program Files'Google'Chrome

尝试这个

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] inputs = {
                  @"c:'folder one'folder2'folder 3",
                  @"''remoteMachine'folder1",
                  @"''1.22.33.444'folder 1'folder2",
                  @"ftp://12.123.112.231/",
                  @"C:'Program Files'Google'Chrome"
                             };
            string ip = @"'d{1,3}'.'d{1,3}'.'d{1,3}'.'d{1,3}";
            string pattern = string.Format( @"^[A-Z]:(''('w+'s*)+)+" + // filename
                             @"|^''''{0}(''('w+'s*)+)+" +              // url with ip
                             @"|^''(''('w+'s*)+)+" +                   // network filename ''abc'def
                             @"|^FTP://{0}/" +                         // ftp with ip
                             @"|^FTP://[A-Z]'w+/", ip);                // ftp with hostname

            foreach (string input in inputs)
            {
                bool match = Regex.IsMatch(input,pattern, RegexOptions.IgnoreCase);
                Console.WriteLine("'"{0}'" {1}", input, match? "matches" : "does not match");
            }
            Console.ReadLine();
        }
    }
}
