帮助C#.使用文件流编辑文件. [英] Help C#. Editing file using filestream.

问题描述

大家好，这是我的第一篇文章.我来自阿根廷，所以我会尽力做到最好的英语.

我需要以下问题的帮助.我使用NetworkStream从客户端应用程序接收到服务器应用程序的文件.收到文件后，我将其临时保存到名为"temp"的硬盘中.接收成功，每个字节都被完美接收.
我用来发送文件的协议是(不带"):"FileName | FileSize | FileContent"
现在，我需要组成最终文件，即原始文件.我可以使用FileStream创建一个新文件，其名称在temp文件中，并且可以读取其大小，但是我不知道如何在新文件中仅写入"temp" FileContent.

Hello everyone, this is my first post. I am from Argentina, so I''ll try to do the best out of my english.

I need help with the following issue. I receive a file from a client application to a server application using NetworkStream. As I receive the file, I save it temporarily to disc in a dile called "temp". The recepcion is succesfull, every byte is receive perfectly.
The protocol I used to send the file is (without "): "FileName|FileSize|FileContent"
Now I need to make up the final file, the original. I can create a new file using FileStream with the name receive in the temp file, as well as I can read its size, but I don''t know how to write only the "temp" FileContent in the new file. Is there any simple way to exclude the FileName and FileSize?

感谢您的回答.
我通过以下方式解决了该问题:接收并存储了临时文件后，我将1024个字节读取到缓冲区中，然后将其转换为字符串，然后使用string.spit(''|'')将名称和文件大小分隔为不同的变量.之后，使用file.seek将红色指针定位到"FileSize |"之后的第一个字节并将所有读数保存到新的最终文件中.

我已阅读了您推荐的文章.顺便说一句很有趣.
能够在读取临时文件的FileName | FileSize字节后将它们删除，然后将临时文件重命名为原始文件，这将是很棒的.我没有找到该怎么做的方法，也没有找到可行的方法.
谢谢!!

Thanks for answering.
I resolve the issue in the following way: After receiving and storing the temp file, I read 1024 bytes to a buffer which I convert to string, then with string.spit(''|'') I separate the name and file size in different variables. After it, with file.seek I positioned the reding pointer to the first byte after "FileSize|" and save all the readings to a new final file.

I have read the articles you recomend. Very interesting by the way.
It would be great to be able to remove the FileName|FileSize bytes of the temporary file after reading them, and then just rename the temp file to become the original file. I didn''t find how to do this, nor if it is posible.
Thanks!!
