】C#将数据写入记事本并且从记事本中读出

写入
C# code oFileStream = new FileStream("文件路径", FileMode.Create, FileAccess.Write, FileShare.ReadWrite); StreamWriter oStreamWriter = new StreamWriter(oFileStream, Encoding.Default); oStreamWriter.Write("要写入内容"); oStreamWriter.WriteLine(); oStreamWriter.Close(); oFileStream.Close();

读取

C# code oFileStream = new FileStream("文件路径", FileMode.Create, FileAccess.Write, FileShare.ReadWrite); StreamReader oStreamReader = new StreamReader(oFileStream, Encoding.Default); string _Text = oStreamReader.ReadToEnd(); oStreamReader.Close(); oFileStream.Close();
