我正在尝试确定文件当前是打开还是使用C#写入.我已经看到类似的SO问题,所有问题都与我的代码类似,它在文件上尝试File.Open.但是当我使用下面的代码运行程序时,我也手动打开文件,我得到“文件当前未锁定”的意外结果.有什么想法/建议/我遗失的任何东西?
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; using System.Threading; namespace TestIfFileAccessed { class Program { static void Main(string[] args) { string path = @"C:\TEMP\testFile.txt"; FileInfo filepath = new FileInfo(path); if (IsFileLocked(filepath)) { Console.WriteLine("File is currently locked"); Console.ReadLine(); } else { Console.WriteLine("File is currently NOT locked"); Console.ReadLine(); } } public static bool IsFileLocked(FileInfo file) { FileStream stream = null; try { stream = file.Open(FileMode.Open,FileAccess.ReadWrite,FileShare.None); } catch (IOException) { //the file is unavailable because it is: //still being written to //or being processed by another thread //or does not exist (has already been processed) return true; } finally { if (stream != null) stream.Close(); } //file is not locked return false; } } }
