我想用C#做一个系统服务，定期清理迅雷下载记录

Question

如何判断下载任务是什么时候的，这样可以清理1周前的。

Answer 1

遍历文件夹获取记文件的修改时间，根据时间判断是否为一周前，再删除文件或记录
 private void GetFolderInfo(string path)
        {
            if (Directory.Exists(path)) 
            {
                if (Directory.GetFileSystemEntries(path).Length == 0) 
                {
                   
                }
                else
                {
                    string[] fileNames0 = Directory.GetFiles(path); 
                    foreach (string file in fileNames0) 
                    {
                     
                    }
                    string[] subdirectoryEntries = Directory.GetDirectories(path);
                    foreach (string subdirectory in subdirectoryEntries)  
                    {
                        GetFolderInfo(subdirectory);
                    }
                }
            }
        }

Answer 2

    string[] fileNames = Directory.GetFiles(path);
                    foreach (string file in fileNames0)
                    {
                        FileInfo f = new FileInfo(s);
                        if (f.Exists&&f.CreationTime=DateTime.Now)
                        {
                            f.Delete();
                        }
                    }

Answer 3

 这代码可以的～

    string[] fileNames = Directory.GetFiles(path);//path迅雷下载文件的绝对路径。
                    foreach (string file in fileNames0)
                    {
                        FileInfo f = new FileInfo(file);
                        if (f.Exists&&f.CreationTime=DateTime.Now)
                        {
                            f.Delete();
                        }
                    }
