如何在C#中删除包含只读文件的目录？
提问于 2009-03-04 18:47:10
我需要删除包含只读文件的目录。哪种方法更好：
使用
ManagementObject.InvokeMethod("Delete")？的- ，或
DirectoryInfo.Delete()
使用DirectoryInfo.Delete()时，我必须手动关闭每个文件的只读属性，但ManagementObject.InvokeMethod("Delete")似乎不需要这样做。有没有哪种情况比另一种更可取？
示例代码(test.txt是只读的)。
第一种方法：
DirectoryInfo dir = new DirectoryInfo(@"C:\Users\David\Desktop\");
dir.CreateSubdirectory("Test");
DirectoryInfo test = new DirectoryInfo(@"C:\Users\David\Desktop\Test\");
File.Copy(@"C:\Users\David\Desktop\test.txt", @"C:\Users\David\Desktop\Test\test.txt");
File.SetAttributes(@"C:\Users\David\Desktop\Test\test.txt", FileAttributes.Archive);
test.Delete(true);第二种方式：
DirectoryInfo dir = new DirectoryInfo(@"C:\Users\David\Desktop\");
dir.CreateSubdirectory("Test");
DirectoryInfo test = new DirectoryInfo(@"C:\Users\David\Desktop\Test\");
File.Copy(@"C:\Users\David\Desktop\test.txt", @"C:\Users\David\Desktop\Test\test.txt");
string folder = @"C:\Users\David\Desktop\Test";
string dirObject = "Win32_Directory.Name='" + folder + "'";
using (ManagementObject managementObject = new ManagementObject(dirObject))
{
managementObject.Get();
ManagementBaseObject outParams = managementObject.InvokeMethod("Delete", null,
null);
// ReturnValue should be 0, else failure
if (Convert.ToInt32(outParams.Properties["ReturnValue"].Value) != 0)
{
}

下面是一个扩展方法，它递归地将Attributes设置为Normal，然后删除这些项：
public static void DeleteReadOnly(this FileSystemInfo fileSystemInfo)
{
var directoryInfo = fileSystemInfo as DirectoryInfo;
if (directoryInfo != null)
{
foreach (FileSystemInfo childInfo in directoryInfo.GetFileSystemInfos())
{
childInfo.DeleteReadOnly();
}
}
fileSystemInfo.Attributes = FileAttributes.Normal;
fileSystemInfo.Delete();

避免递归调用的最简单方法是在获取FileSystemInfo时使用AllDirectories选项，如下所示：
public static void ForceDeleteDirectory(string path)
{
var directory = new DirectoryInfo(path) { Attributes = FileAttributes.Normal };
foreach (var info in directory.GetFileSystemInfos("*", SearchOption.AllDirectories))
{
info.Attributes = FileAttributes.Normal;
}
directory.Delete(true);

尝尝这个,
private void DeleteRecursiveFolder(string pFolderPath)
{
foreach (string Folder in Directory.GetDirectories(pFolderPath))
{
DeleteRecursiveFolder(Folder);
}
foreach (string file in Directory.GetFiles(pFolderPath))
{
var pPath = Path.Combine(pFolderPath, file);
FileInfo fi = new FileInfo(pPath);
File.SetAttributes(pPath, FileAttributes.Normal);
File.Delete(file);
}
Directory.Delete(pFolderPath);
