Answer 3

  嗯，以前做个这样的小程序。在以前360壁纸还没有保存的功能，我就把它缓存的文件夹中的文件进行分辨并复制(加上特定编号)到其他其他文件夹里。
   分辨就是获取问价的属性，复制调用方法.....应该很好写，想要什么方法，但是又不知道方法名可以MSDN或度娘等

Answer 4

以前写个一个这样的列子，// dir 是源文件
private void GetUpdateFile(DirectoryInfo dir)
 {
           //formtime 起始时间 
            DateTime fromtime = DateTime.Parse(dtPicker.Text + " " + cbbhour.Text +":"+ cbbminute.Text);
            FileInfo[] allFile = dir.GetFiles();
            foreach (FileInfo fi in allFile)
            {
               //在这里加上一个条件小于你的totime就行
                if (fi.LastWriteTime > fromtime)
                {
                    if (!txtsource.Text.Equals(dir.FullName))
                    {
                        if (!Directory.Exists(txtdest.Text + "\\" + dir.FullName.Substring(txtsource.Text.Length)))
                            Directory.CreateDirectory(txtdest.Text + "\\" + dir.FullName.Substring(txtsource.Text.Length));
                          File.Copy(dir.FullName + "\\" + fi.Name, txtdest.Text + "\\" + dir.FullName.Substring(txtsource.Text.Length) + "\\" + fi.Name);
                    }
                    else
                    {
                        File.Copy(txtsource.Text + "\\" + fi.Name, txtdest.Text + "\\" + fi.Name);
                    }
                }            }                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
            DirectoryInfo[] allDir = dir.GetDirectories();
            foreach (DirectoryInfo d in allDir)
            {
                GetUpdateFile(d);
            }
        }

Answer 5

FileInfo, DirectoryInfo, 并且用递归进行遍历
