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
