File.Delete拒绝访问该路径 [英] File.Delete Access to the path is denied

问题描述

我的控制台应用程序正在运行时正在创建一些运行时文件，因此我想做的是在应用程序启动时删除所有这些文件.我已经尝试过:

My console application program is creating some runtime files while it is working so what I want to do is delete all of these files on the application startup. I have tried this:

public static void Empty(string targetDir)
{
    var directory = new DirectoryInfo(targetDir);
    if (!directory.Exists) return;
    foreach (var file in directory.GetFiles()) file.Delete();
    foreach (var subDirectory in directory.GetDirectories()) subDirectory.Delete(true);
}

...只是在给定路径(位于程序执行路径的子目录中)中查找所有文件/文件夹，然后将其删除.但是，出现以下异常:

...just to look for all the files/folders in the given path (which is in a subdirectory in the program execution path) then delete them. However, I get the following exception:

拒绝访问文件"路径.

Access to the path 'file' is denied.

我试图以管理员身份运行该程序，但是没有运气.但是，我需要一种无需使用管理员权限即可使用的解决方案.

I tried to run the program as administrator with no luck; However, I want a solution that works without using administrator privileges.

注意:

1. 该文件未在其他应用程序中运行.
2. 该文件不在受保护的文件夹中.
3. 可以毫无问题地手动删除文件，这就是为什么我 在这里.

1. The file is not running in another application.
2. The file is not in a protected folder.
3. The file can be deleted manually with no problems and that's why i am here.

推荐答案

尝试使用Microsoft.VisualBasic.FileIO.FileSystem方法，因为它具有方便的DeleteDirectory方法，我前一段时间遇到了访问麻烦，这是解决我的问题的方法. /p>

Try using the Microsoft.VisualBasic.FileIO.FileSystem methods as it has a handy DeleteDirectory method, I had access troubles awhile ago and this was the fix for my problem.

var directory = new DirectoryInfo(targetDir);
if (directory.Exists)
{
    Microsoft.VisualBasic.FileIO.FileSystem.DeleteDirectory(targetDir, Microsoft.VisualBasic.FileIO.DeleteDirectoryOption.DeleteAllContents);
}
