问题描述

public static Boolean IsFileLocked(FileInfo file)
        {
            FileStream stream = null;
            try
            {
                stream = file.Open(FileMode.Truncate, FileAccess.Write, FileShare.None);
                //using (StreamReader reader = new StreamReader(File.Open(filePath, FileMode.Open, FileAccess.ReadWrite)))
                //{
                //    return false;
                //}
            }
            catch (IOException)
            {
                return true;
            }
            finally
            {
                if (stream != null)
                    stream.Close();
            }
            return false;
        }

推荐答案

如果你回去原始来源，据我所知，这里是： http://stackoverflow.com/questions/876473/is-there-a-way-to-check-if-a-file-is-in-use [ ^ ]

它使用FileMode.Open，而不是FileMode.Truncate，而FileMode.ReadWrite则不是FileMode.Write - 它可能值得回到原始版本，因为它确实有效。

If you go back to the original source, which as far as I know is here: http://stackoverflow.com/questions/876473/is-there-a-way-to-check-if-a-file-is-in-use[^]
It uses FileMode.Open, not FileMode.Truncate, and FileMode.ReadWrite not FileMode.Write - it's probably worth going back to the original, because that does work.
