1、C#读文件
按行读取文件：

public void Read(string path) { StreamReader sr = new StreamReader(path,Encoding.Default); String line; while ((line = sr.ReadLine()) != null) { Console.WriteLine(line.ToString()); } }

2、写文件

public void Write(string path) { FileStream fs = new FileStream(path, FileMode.Create); StreamWriter sw = new StreamWriter(fs); //开始写入 sw.Write("Hello World!!!!"); //清空缓冲区 sw.Flush(); //关闭流 sw.Close(); fs.Close(); }
