DictionaryEntry是单个键值对的类型
利用list的特性，完成按添加顺序排好的键值对
public List<DictionaryEntry> UrlList { get { return urlList; } }
DictionaryEntry de = new DictionaryEntry();
de.Key = dph.FilePath; de.Value = dph.ImgUrl;
urlList.Add(de);
foreach (DictionaryEntry de in urllist)
{
System.Drawing.Image tempimage = System.Drawing.Image.FromFile(de.Key.ToString());//图片路径
int imagewidth = tempimage.Width;//宽
int imageheight = tempimage.Height;//高
if (imagewidth > 320 && imageheight > 320)
{
dph.GetPicThumbnail(320, 320, 50, de.Key.ToString());
break;
}
}
}
