<p>2.scan without a folder</p> <p>直接扫描</p> <p>this only work on android,and you need take read/writeExternalStorgae permission</p> <p>只有安卓能这样做,而且你必须获得读写外部权限</p> <code> var status = await Permissions.CheckStatusAsync<Permissions.StorageRead>(); if (status != PermissionStatus.Granted) { status = await Permissions.RequestAsync<Permissions.StorageRead>(); if (status != PermissionStatus.Granted) { //未获取到权限 } } var options = new FileScanOption { FileType = FileType.Video,
//可以对文件名进行条件筛选,支持的语句将会转化为sql条件语句,不支持的将在扫描后过滤 //FileNameExpression = s ⇒ s.StartsWith("S") }; await Task.Run(() ⇒ MKFileScanner.MKFileScanner.Scan(null, options, OnFileScanned)); </code> <p>you can set FileScanOption.FileType to set which collection you want to scan </p> <p>你可以设置FileType的值来设置你想扫描哪个集合</p>

<p>3,scan file use option</p> <p>对扫描结果过滤</p> <p>limit file extension</p> <p>限制文件拓展名</p> <code> var options = new FileScanOption(); options.Extensions = new string[] { "jpg", "png" }; </code> <p>filter file name</p> <p>筛选文件名</p> <code> options.FileNameExpression = s ⇒ s.StartsWith("S"); </code> <p>file size bigger than 1kB and create time less one day</p> <p>筛选文件大于1kB且一天以内创建的</p> <code> options.MinFileSize = 1000; options.MinCreateTime = DateTime.Now - TimeSpan.FromDays(1); </code>
