File.Create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File.Create() 已经帮大家高亮显示了，大家可以重点学习File.Create() 方法的写法，从而快速掌握该方法的应用。

File.Create的代码示例1 - NewFileAttributesAreUpdated()

    using System.IO;

        [TestCaseSource(typeof(FileRunnersAndFolders), nameof(FileRunnersAndFolders.Folders))]
        public void NewFileAttributesAreUpdated(string parentFolder)
        {
            string filename = Path.Combine(parentFolder, "FileAttributesAreUpdated");
            FileSystemRunner fileSystem = FileSystemRunner.DefaultRunner;

            string virtualFile = this.Enlistment.GetVirtualPathTo(filename);
            virtualFile.ShouldNotExistOnDisk(fileSystem);

            File.Create(virtualFile).Dispose();
            virtualFile.ShouldBeAFile(fileSystem);

            // Update defaults. FileInfo is not batched, so each of these will create a separate Open-Update-Close set.
            FileInfo before = new FileInfo(virtualFile);
            DateTime testValue = DateTime.Now + TimeSpan.FromDays(1);
            before.CreationTime = testValue;
            before.LastAccessTime = testValue;
            before.LastWriteTime = testValue;
            before.Attributes = FileAttributes.Hidden;

            // FileInfo caches information. We can refresh, but just to be absolutely sure...
            virtualFile.ShouldBeAFile(fileSystem).WithInfo(testValue, testValue, testValue, FileAttributes.Hidden);

            File.Delete(virtualFile);
            virtualFile.ShouldNotExistOnDisk(fileSystem);
        }
