1、读取文件ReadFile

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.IO;namespace TestReadFile{ class PRogram { static void Main(string[] args) { FileStream fs = new FileStream("D://Wordlist.txt",FileMode.Open,File access.Read); //*.txt--->FileStream StreamReader sr = new StreamReader(fs); //FileStream--->StreamReader string line = sr.ReadLine(); //StreamReader--->line while (line != null) { Console.WriteLine(line); Console.ReadKey(); line = sr.ReadLine(); } sr.Close(); fs.Close(); } }}

2、写文件WriteFile

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.IO;namespace TestWriteFile{ class Program { static void Main(string[] args) { FileStream fs = new FileStream("d://test.txt",FileMode.Create,FileAccess.Write); StreamWriter sw = new StreamWriter(fs); sw.BaseStream.Seek(0, SeekOrigin.End); sw.WriteLine("first line"); sw.WriteLine("second line"); sw.Flush(); fs.Close(); } }}
