C#操作txt文件,进行清空添加操作的例子。
代码:
//把txt清空 FileStream stream = File.Open(Adr,FileMode.OpenOrCreate,FileAccess.Write); stream.Seek(0, SeekOrigin.Begin); stream.SetLength(0); stream.Close(); //向txt里面追加信息 StreamWriter sw = new StreamWriter(Adr,true,Encoding.GetEncoding("gb2312")); sw.WriteLine(str); sw.Flush(); sw.Close(); //edit:www.jbxue.com
