Directory.Delete的代码示例1 - NewFolderAttributesAreUpdated()
using System.IO;
[TestCaseSource(typeof(FileRunnersAndFolders), nameof(FileRunnersAndFolders.Folders))]
public void NewFolderAttributesAreUpdated(string parentFolder)
{
string folderName = Path.Combine(parentFolder, "FolderAttributesAreUpdated");
string virtualFolder = this.Enlistment.GetVirtualPathTo(folderName);
Directory.CreateDirectory(virtualFolder);
FileSystemRunner fileSystem = FileSystemRunner.DefaultRunner;
virtualFolder.ShouldBeADirectory(fileSystem);
// Update defaults. DirectoryInfo is not batched, so each of these will create a separate Open-Update-Close set.
DirectoryInfo before = new DirectoryInfo(virtualFolder);
DateTime testValue = DateTime.Now + TimeSpan.FromDays(1);
before.CreationTime = testValue;
before.LastAccessTime = testValue;
before.LastWriteTime = testValue;
before.Attributes = FileAttributes.Hidden;
// DirectoryInfo caches information. We can refresh, but just to be absolutely sure...
virtualFolder.ShouldBeADirectory(fileSystem)
.WithInfo(testValue, testValue, testValue, FileAttributes.Hidden | FileAttributes.Directory, ignoreRecallAttributes: false);
Directory.Delete(virtualFolder);
