从多个子目录中的多个文件中删除扩展名 [英] Remove extension from multiple files in multiple sub directories

问题描述

亲爱的所有人，



我想从主文件夹中所有子文件夹中的所有可用文件中删除扩展名。



示例：下面是文件夹结构。

Dear All,

I want to remove the extension from all the available files in all the sub folders in a Main folder.

Example : Below is the folder structure.

MainDirectory
|
|---> SubDirectory1/ abc1.config.txt / abc2.config.txt /  abc3.config.txt /
|
|---> SubDirectory2/ abc1.config.txt / abc2.config.txt /  abc3.config.txt /
|
|---> SubDirectory3/ abc1.config.txt / abc2.config.txt /  abc3.config.txt /

所以，我想要从所有的.txt扩展名中删除以c＃编程的所有子目录中的文件，这样我最后只会有配置文件。



请建议或提供一些c＃代码。



提前致谢，



我尝试过：



我已经尝试过Path.ChangeExtension，它实际上用null替换了扩展名，但它不适用于物理文件。我的意思是，它只是以逻辑方式给用户赋值。

So, I want ".txt" extension to be removed from all the files in all the sub directories programmatically in c#, so that I will be having only config files at the end.

Please suggest or provide some piece of c# code.

Thanks in advance,

What I have tried:

I have tried Path.ChangeExtension which actually replaces the extension with null, but it does not apply for physical file. I mean, it just gives the value to the user in logical way.

推荐答案

更改扩展后，需要使用文件移动方法（字符串，字符串）（System.IO） [ ^ ]重命名。

Once you have changed the extension you need to use File.Move Method (String, String) (System.IO)[^] to rename it.

尝试：

Try:

string[] files = Directory.GetFiles(@"D:\Temp\", "*.txt", SearchOption.AllDirectories);
foreach (string file in files)
    {
    File.Move(file, file.Substring(0, file.Length - 4));
    }

您可以调用'移动文件，同时删除.txt扩展名，这将导致扩展名为。 config：

You can call 'Move on the File, while removing the ".txt" extension, which will result in the extension being ".config:"

string path = @"C:\Users\Whoever\Desktop\SubDirectory1\abc1.txt.config";

string newpath = Path.ChangeExtension(path, "");
File.Move(path, newpath);

虽然这个有效，但是以这种方式操作文件扩展名的需要让我想知道是否有更简单的方法可以做任何事情你在这里做什么。

While this "works," the need to manipulate file extensions in this way makes me wonder if there isn't a simpler way to do whatever it is you are doing here.
