FileWatcher

C# 基于FileSystemWatcher类对目录和文件夹的改变监控. 解决了同一文件在复制或新建文件时会触发多次 new 和 changed 事件的问题

示例

class Program
{
    static void Main(string[] args)
    {
        //目录下的文件
        FileWatcher fileWatcher = new FileWatcher("C:\\test", "*.xml");
        fileWatcher.Open();
        var task = FileChangedQueue(fileWatcher);
        //task.Wait();
        //目录
        FileWatcher fileWatcher2 = new FileWatcher("C:\\test");
        fileWatcher2.NotifyFilter = NotifyFilters.DirectoryName;
        fileWatcher2.Open();
        var task2 = FileChangedQueue(fileWatcher2);
        task2.Wait();
    }

    private static async Task FileChangedQueue(FileWatcher fileWatcher)
    {
         
        while (true)
        {
            if (fileWatcher.IsWatch)
            {
                if (fileWatcher.FileChangeQueue.Count == 0)
                {
                    await Task.Delay(100);
                    continue;
                }
                var (isok,fci)= fileWatcher.GetDequeue();
                if(!isok || fci==null)
                {
                    await Task.Delay(100);
                    continue;
                }
                if(fci.ChangeType== FileChangeType.Rename)
                {
                    Console.WriteLine($"{DateTime.Now:HH:mm:ss.fff} ：{fci.ChangeType.ToString()} >> {fci.OldFullPath} >>> {fci.FullPath}");
                }
                else
                    Console.WriteLine($"{DateTime.Now:HH:mm:ss.fff} ：{fci.ChangeType.ToString()} >> {fci.FullPath} >>> {fci.Name}");

            }
            else
            {
                fileWatcher.Open();
                await Task.Delay(100);
            }
        }
    }
}
