C#返回指定目录最后写入时间,主要用到了DirectoryInfo的LastWriteTime属性
using System; using System.IO; class MainClass { static void Main(string[] args) { FileInfo file = new FileInfo("c:\\a.txt"); // Display directory information. DirectoryInfo dir = file.Directory; Console.WriteLine("Checking directory: " + dir.Name); Console.WriteLine("In directory: " + dir.Name); Console.Write("Directory exists: "); Console.WriteLine(dir.Exists.ToString()); if (dir.Exists) { Console.Write("Directory last updated: "); Console.WriteLine(dir.LastWriteTime.ToString()); } Console.WriteLine(); } }
