我用multi file upload在ASP.Net中上傳文件沒有問題。但現在我要像創建縮略圖添加更多的功能,同時在下面上傳是我的代碼:多文件上傳問題
try
{
string _path = "~/photos/realimg/";
string _thumPath = "~/photos/thumbimg/";
// Get the HttpFileCollection
HttpFileCollection hfc = Request.Files;
for (int i = 0; i < hfc.Count; i++)
{
HttpPostedFile hpf = hfc[i];
if (hpf.ContentLength > 0)
{
_path += System.IO.Path.GetFileName(hpf.FileName);
_thumPath += System.IO.Path.GetFileName(hpf.FileName.Insert(0, "thumb_"));
hpf.SaveAs(Server.MapPath(_path));
SavePicPath(_path);
System.Drawing.Image realImg = System.Drawing.Image.FromFile(Server.MapPath(_path));
Int32 rH = realImg.Height;
Int32 rW = realImg.Width;
Int32 fW = 170;
Int32 fH = (Int32)Math.Floor((double)rH * (fW/rW));
System.Drawing.Image thumbimg = realImg.GetThumbnailImage(fW, fH, null, IntPtr.Zero);
thumbimg.Save(Server.MapPath(_thumPath));
SavePicPath(_thumPath);
}
}
}
catch
{
}
每當它進入GetThumbnailImage我得到一個錯誤「內存不足」取悅任何修正或我在做什麼錯
將int值更改爲(float或double) – MMK 2012-08-13 12:42:32
@MMK感謝它的工作!但請說明它背後的祕密是什麼? – 2012-08-13 13:46:35
