提取的文件始终是只读的 [英] Extracted Files are always read-only

问题描述

我要提取一个ISO，然后从提取的ISO中复制一个文件夹.问题在于提取的文件是只读的.我试过从属性菜单和c#中的代码更改它.都不起作用.

I'm extracting an ISO and then copying a folder from the extracted ISO. The problem is that the extracted files are read-only. I've tried changing it from the properties menu, and from code in c#. Neither worked.

我用于提取ISO的代码在另一个问题中:

The code I used for extracting the ISO is in another question: extract ISO with winrar automatically with c# or batch

我正在寻找一种方法来更改提取的ISO的属性，以便可以从其子文件夹进行复制，或者仅更改子文件夹的权限.

I'm looking for a way to either change the attributes of the extracted ISO so that I can copy from its subfolders, or to just change the sub folders permissons.

预先感谢

更新

新代码

 string[] folderToName = txtCopyFrom.Text.Split('\\');
        string isoName = folderToName[folderToName.Length - 1];
        isoName = isoName.Remove(isoName.Length - 4, 4);

        string copyTestFrom = txtCopyTo.Text + @"\"+ isoName + @"\Test\subTest";
        string[] folderName = txtCopyFrom.Text.Split('\\');
        string folderTestTo = folderName[folderName.Length - 1];
        folderTestTo = folderTestTo.Remove(folderTestTo.Length - 4, 4);
        string copyTest = txtCopyTo.Text;
        System.IO.Directory.CreateDirectory(copyTest);

        DirectoryInfo di = new DirectoryInfo(copyTestFrom);
        di.Attributes &= ~FileAttributes.ReadOnly;

        foreach (FileInfo fi in di.GetFiles())
        {
            fi.IsReadOnly = false;

            string destinationPath = Path.Combine(copyTest, Path.GetFileName(copyTestFrom));
            File.Copy(copyTestFrom, destinationPath);
        }
        MessageBox.Show("Files Copied");   

subTest中的文件不是只读的，只有文件夹本身是

The files in subTest are not read only, only the folder itself is.

目标路径转到C:\ users \ mydocs \ ISODump \ subTest

Destination path goes to C:\users\mydocs\ISODump\subTest

引发access denied异常后，我仍然可以手动复制文件夹

After access denied exception is thrown I can still copy the folder manually

解决方法

出于我的目的，找到了解决方法. directory.move通过移动文件夹而不是复制文件夹来达到我想要的目的.

Found a work around, for my purposes. directory.move achieves the purpose I wanted by moving the folder, instead of copying it.

谢谢

推荐答案

您可以尝试更改属性:

foreach (string fileName in System.IO.Directory.GetFiles(path))
{
    System.IO.FileInfo fileInfo = new System.IO.FileInfo(fileName);

    fileInfo.Attributes |= System.IO.FileAttributes.ReadOnly;
    // or
    fileInfo.IsReadOnly = true;
}

您可以尝试将此属性以递归方式设置到所有子目录和文件:

You can try this to recursively set the attribute to all sub directories and files :

DirectoryInfo di = new DirectoryInfo(directorypath);
public void Recurse(DirectoryInfo directory)
{
    foreach (FileInfo fi in directory.GetFiles())
    {
        fi.IsReadOnly = false; // or true
    }

    foreach (DirectoryInfo subdir in directory.GetDirectories())
    {
        Recurse(subdir);
    }
}

测试用户是否有权访问文件夹-检查， 如果仍然存在问题，那么我认为解决方案应该使用 Windows Shell API
