C# Directory.Delete的代码示例

通过代码示例来学习C# Directory.Delete方法

通过代码示例来学习编程是非常高效的。
1. 代码示例提供了一个具体而直观的学习环境，使初学者能够立即看到编程概念和语法的实际应用。
2. 通过分析和模仿现有的代码实例，初学者可以更好地理解编程逻辑和算法的工作原理。
3. 代码实例往往涵盖了多种编程技巧和最佳实践，通过学习和模仿这些实例，学习者可以逐步掌握如何编写高效、可读性强和可维护的代码。这对于初学者来说，是一种快速提升编程水平的有效途径。


Directory.Delete是C#的System.IO命名空间下中的一个方法, 小编为大家找了一些网络大拿们常见的代码示例，源码中的Directory.Delete() 已经帮大家高亮显示了，大家可以重点学习Directory.Delete() 方法的写法，从而快速掌握该方法的应用。

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);
        }
