当应用程序在c＃中运行时如何从文本文件中读取数据 [英] How to read data from the text file when an application runs in c#

问题描述

嗨


我在c＃中创建了一个表单，有2个按钮，第一个按钮是访问我使用matlab开发的应用程序（.exe文件），执行后应用程序，数据应保存到文本文件。



第二个按钮是在文本框中查看数据（保存在上面的文本文件中）



当我单击第一个按钮时，.exe文件运行，我可以看到.exe文件。如果我关闭应用程序，然后单击第二个按钮，则出现错误即将到来，



错误：进程无法访问文件，因为它正在被另一个进程使用/>


如何解决问题

这件事很容易调查。请参阅我以前的回答：如何在vb.net中压缩错误'它已被另一个进程使用' [ ^ ]。

This thing is pretty easy to investigate. Please see my past answer: how to compress the error 'it is already used by another process' in vb.net[^].

错误非常清楚。有些东西仍然有文件处理。也许这是你的代码，或者你打开它来验证它是否存在。

The error is pretty clear. Something still has a handle on the file. Perhaps it's your code or perhaps you opened it to verify it was there.
