需要引用:System.IO这个命名空间
代码演示:
1 string path = @"F:\a.txt"; 2 string content = "内容"; 3 try 4 { 5 //创建文件流 6 FileStream fs = new FileStream(path, FileMode.Create); 7 //创建写入器,将文件流传入写入器 8 StreamWriter w = new StreamWriter(fs); 9 //执行操作 10 w.Write(content); 11 //关闭写入器 12 w.Close(); 13 //关闭文件流 14 fs.Close(); 15 Console.WriteLine("写入成功!"); 16 } 17 catch (Exception ex) 18 { 19 Console.WriteLine("发生错误!"+ex.Message); 20 }
FileStream的path参数为空时会引发异常
FileMode枚举常用的值有:
StreamWriter构造时可以指定编码枚举类型Encoding
常用的Encoding的值有:
其他编码可以使用Encoding的静态方法GetEncoding(string name)指定字符编码,当然得是C#能支持的编码名
给出一个C#支持的编码大全:(GetEncodings()遍历出来的)

----文件的读取流程和写入的是一样的
创建读取器差不太多(替换上面的7-12行,根据情况修改FileMode即可)
1 //创建读取器 2 StreamReader reader = new StreamReader(fs); 3 //读取内容到变量 4 string content=reader.ReadToEnd(); 5 //关闭读取器 6 reader.Close();
希望对正在学习文件操作的小伙伴有帮助
