C# 获取文件夹文件名

ou.cs 人气:0

主要是这个方法

 List<string> GetAllFileNames(string path,string pattern="*")
        {
            List<FileInfo> folder  = new DirectoryInfo(path).GetFiles(pattern).ToList();

            return folder.Select(x=>x.Name).ToList();
        }
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace GetFileNames
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();

            textBox1.Text = @"D:\jdScript\jdpro-main";
            textBox2.Text = "*.js";
        }

        string _outFileName = "aaaa.bat";

        private void button1_Click(object sender, EventArgs e)
        {
            foreach (var fileName in GetAllFileNames(textBox1.Text))
            {
                richTextBox1.AppendText("node " + fileName + '\n');
            }

            OutputFile(textBox1.Text + "\"+ _outFileName, richTextBox1.Text);
        }

        void OutputFile(string strFilePath,string strContent)
        {
            StreamWriter swOut = new StreamWriter(strFilePath, false, Encoding.Default);
            swOut.WriteLine(strContent);
            swOut.Flush();
            swOut.Close();
        }

        List<string> GetAllFileNames(string path,string pattern="*")
        {
            List<FileInfo> folder  = new DirectoryInfo(path).GetFiles(pattern).ToList();

            return folder.Select(x=>x.Name).ToList();
        }

    }
}

补充:C# 正则表达式分组查询

result[1] = "memory usage threshold: 80 %";
strResult = Regex.Match(result[1], @"(?<a>\d+)\s*%").Groups["a"].ToString();

分组的命名方式为:(?< groupname > exp) 捕获exp
