Question

我有一个我的文件夹结构预先设置的统一包，但是意味着是空的，为了导出文件夹我把文件“Delete This File.txt”放到结构中的每个底部文件夹中以允许统一到导出文件夹，但我想写一个在启动时运行的脚本删除这些文件，但我似乎无法让脚本找到各个文件夹中的所有文件。我该怎么做？

using UnityEngine;
using UnityEditor;
using System.IO;

[InitializeOnLoad]
public class Startup {
    static Startup()
    {
        foreach (string file in Directory.GetFiles("Assets/")) {

            if (file == "Delete This File.txt") {
                Debug.Log (file);
            } else {
                // Do Nothing
            }
        }
    }
}

Answer 1

您的代码中需要进行一些更改

[InitializeOnLoad]
public class Startup {
static Startup()
{
    // unfortunately this is not available in NET 3.5
    // foreach (string file in Directory.EnumerateFiles.....
    foreach (string file in Directory.GetFiles("Assets", "Delete This File.txt", SearchOption.AllDirectories)) 
    {
         Debug.Log (file);
         // File.Delete(file);      
    }
}

此方法使用Directory.GetFiles的重载，该重载采用初始目录，要搜索的模式以及搜索根的所有子目录的选项。生成的字符串是要删除的完整文件名。

此外，在.NET 4.0中，Directory.EnumerateFiles有一个更好的选项，如the MSDN docs所述

EnumerateFiles和GetFiles方法的区别如下：当你使用EnumerateFiles，您可以开始枚举名称集合在整个收藏品归还之前;当你使用GetFiles时，你必须等待返回整个名称数组才能返回访问数组。因此，当您使用许多文件和目录，EnumerateFiles可以更有效。

这可以通过Directory.GetFiles，Directory.GetDirectories和FileInfo类的组合来完成。我修改了Microsoft的RecursiveFileProcessor代码example并添加了FileInfo和if语句，以便找到所有名为＆＃34; Delete This File.txt＆＃34;的文件。并删除它们。

using UnityEngine;
using UnityEditor;
using System.IO;

[InitializeOnLoad]
public class Startup 
{
    static Startup()
    {
        ProcessDirectory("Assets/");
    }

    public static void ProcessDirectory(string targetDirectory)
    {
        // Process the list of files found in the directory.
        string[] fileEntries = Directory.GetFiles(targetDirectory);
        foreach (string filePath in fileEntries)
        {
            FileInfo fileInfo = new FileInfo(filePath);

            if (fileInfo.Name == "Delete This File.txt")
            {
                ProcessFile(filePath);
            }
        }

        // Recurse into subdirectories of this directory.
        string[] subdirectoryEntries = Directory.GetDirectories(targetDirectory);
        foreach (string subdirectory in subdirectoryEntries)
        {
            ProcessDirectory(subdirectory);
        }
    }

    // Insert logic for processing found files here.
    public static void ProcessFile(string path)
    {
        Debug.Log("Processed file " + path);

        //Delete File
        File.Delete(path);
    }
}

Answer 3

After discovering that Directory.EnumerateFiles wasn't an option for me I tried the same method with the get files, and found a solution that works. This code not only deletes the text file but the meta file that is associated with it, counting the number of times a text file was deleted and informing me how many were deleted in the log.

using UnityEngine;
using UnityEditor;
using System.IO;

/*   Project Name : Ember Guard
 *    Script Name : RemoveDeleteFile
 *    Script Path : Assets/Editor/RemoveDeleteFile.cs
 *  Script Author : FaalFaazDov || Raisltin M. Thoreson

 *    Modified On : N/A
 *        Version : 0.0.1Alpha

[InitializeOnLoad]
public class Startup {

    static Startup()
    {

        int x = 0;

        string path = Application.dataPath;

        string[] files = Directory.GetFiles (path, "Delete This File.txt", SearchOption.AllDirectories);

        foreach (string f in files) {

            File.Delete (f);
            File.Delete (f + ".meta");

            x++;

        }

        string fm;

        if (x == 1) {
            fm = "file";
        } else {
            fm = "files";
        }

        Debug.Log ("Deleted " + x + " " + fm + ".");

    }

}

Unity查找并删除名为“Delete This File.txt”的所有文件
