如何在不使用保存文件对话框的情况下覆盖文本文件？ [英] How to overwrite text file without using Save file dialog?

问题描述

大家好，我正在使用VB 2008而且我遇到了问题。



我正在制作一个html编辑器并制作语法等所有内容。

但我知道如何保存文件，但我不知道如何覆盖它。就像'当你正在编辑文本文件时，按ctrl + s它会自动保存。

怎么办？谢谢你提前帮忙。

推荐答案

只需编写文件。

File.WriteAllText [ ^ ]只需要你提供文件的路径和要写入的数据（还有其他File.WriteXXX方法对不同类型的数据执行相同操作） - 如果您已经有文件名和路径，则无需再次询问 - 只需调用适当的方法并编写它。



尽管提供备份工具是个好主意：将文件写入同一文件夹中的临时文件，然后重命名原始，然后重命名新文件。这样，如果用户的更新导致问题，用户可以退后一步。

Just write the file.
File.WriteAllText[^] just needs you to supply the path to the file, and the data to write (and there are other File.WriteXXX methods that do the same for different types of data) - provided you have a file name and path already, you don't need to ask again - just call the appropriate method and it's written.

It's a good idea to provide a backup facility though: write the file to a temporary file in the same folder, then rename the original, then rename the new file. That way, the user can "step back" if his updates caused a problem.
