Question

我有一个本地的网站项目，并与数据库连接，服务器中的数据库。我可以添加我在本地工作的照片和国家，但我无法添加我将项目加载到服务器

public void resim_ekle（） { if（FileUpload1.HasFile） { 尝试 { string fileExtension = Path.GetExtension（FileUpload1.FileName）.ToLower（）;

            string fileName = Guid.NewGuid().ToString(); // şifreli isim
            string fileName2 = Guid.NewGuid().ToString();

            if (File.Exists(fileName + fileExtension))
                fileName = Guid.NewGuid().ToString();
            if (File.Exists(fileName2 + fileExtension))
                fileName2 = Guid.NewGuid().ToString();

            if (FileUpload1.FileContent == null)
                return;
            if (FileUpload1.FileContent.Length == 0)
                return;

            System.Drawing.Bitmap originalBMP = new System.Drawing.Bitmap(FileUpload1.FileContent);

            int origWidth = 800;
            int origHeight = 600;

            int origWidth2 = 120;
            int origHeight2 = 90;

            double sgnRatio = Convert.ToDouble(origWidth) / Convert.ToDouble(origHeight);
            double sgnRatio2 = Convert.ToDouble(origWidth2) / Convert.ToDouble(origHeight2);

            System.Drawing.Bitmap newBMP = new System.Drawing.Bitmap(originalBMP, origWidth, origHeight);
            System.Drawing.Bitmap newBMP2 = new System.Drawing.Bitmap(originalBMP, origWidth2, origHeight2);

            System.Drawing.Graphics oGraphics = System.Drawing.Graphics.FromImage(newBMP);
            System.Drawing.Graphics oGraphics2 = System.Drawing.Graphics.FromImage(newBMP2);

            oGraphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighSpeed;
            oGraphics2.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighSpeed;

            oGraphics.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.Low;
            oGraphics2.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.Low;

            oGraphics.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighSpeed;
            oGraphics2.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighSpeed;

            oGraphics.DrawImage(originalBMP, 0, 0, origWidth, origHeight);
            oGraphics2.DrawImage(originalBMP, 0, 0, origWidth2, origHeight2);

            newBMP.Save(Server.MapPath("~/resimler/olkeler/" + fileName.ToString() + fileExtension));
            newBMP2.Save(Server.MapPath("~/resimler/olkeler/kucuk/" + fileName2.ToString() + fileExtension));


            olkeler ulke = new olkeler();



            ulke.resim_buyuk = ("~/resimler/olkeler/" + fileName.ToString() + fileExtension).ToString();
            ulke.resim_kucuk = ("~/resimler/olkeler/kucuk/" + fileName2.ToString() + fileExtension).ToString();
            ulke.olke_adi = txtulke_adi.Text;
            vt.insert_ulke(ulke);

            label_Uyari.Text = "Resim Başarıyla Yüklendi...";
        }
        catch { label_Uyari.Text = "Resim Yükleme İşlemi Esnasında Bir Hata Oluştu. Lütfen Tekrar Deneyiniz..."; }
    }
    else { label_Uyari.Text = "Resim Seçilmemiş..."; }

}

此代码在我的loclhost中运行，但在服务器中不起作用。 FileUpload1在服务器中没有文件

Answer 1

我认为你的

是错的

newBMP.Save(Server.MapPath("~/resimler/olkeler/" + fileName.ToString() + fileExtension));

我认为你应该放弃〜

我写道：

profilPic.SaveAs(Server.MapPath(@"images/people/") +
                                 profilPic.FileName);

从这里开始：

<asp:FileUpload ID="profilPic" runat="server" />

ASP.NET fileupload在服务器中不起作用
