  • StreamReader和StreamWriter读取写入文本文件

    StreamReader和StreamWriter适合读取写入文本文件

    using System;
    using System.Collections.Generic;
    using System.IO;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;
    
    namespace StreamReaderAndWriter
    {
        class Program
        {
            static void Main(string[] args)
            {
                //一般用流的方法
                //StreamWriter(Stream stream);推荐使用,灵活便于理解多态
                //StreamWriter(string  path);写死了就是指向硬盘写文件
                string inpath = @"F:1.txt";
                string outpath = @"D:2.txt";
                //
                using (Stream outStream = new FileStream(outpath, FileMode.Create))
                using (StreamWriter sw = new StreamWriter(outStream, Encoding.Default))
                {
                    sw.Write("你好");
                    sw.WriteLine("hehe");
                    sw.WriteLine("111");
                }
    
                //
                using (Stream intStream = new FileStream(inpath, FileMode.Open))
                using (StreamReader reader = new StreamReader(intStream, Encoding.Default))
                {
                    /*
        string s = reader.ReadToEnd();
        Console.Write(s);*/
                    /*
                    string s1 = reader.ReadLine();
                    Console.WriteLine(s1);
     
                    string s2 = reader.ReadLine();
                    Console.WriteLine(s2);
                        */
                    string line;
                    while ((line = reader.ReadLine()) != null)
                    {
                        Console.WriteLine(line);
                    }
    
                }
    
                Console.ReadKey();
    
    
    
    
            }
        }
    }
