如何在服务器上传图像 [英] How to upload image in server

问题描述

如何在具有特定大小的服务器上上传图像并在数据库中保存路径

解决方案

您无法控制用户发送给您的图像的大小：全部您可以做的是接收上传文件，将其加载到图像中并检查尺寸。如有必要，您可以重新缩放它（Google会帮助您），或拒绝它，以便用户上传另一个。

How to upload image in server with specific size and save path in database

解决方案

You can't control the size of the image the user sends you: all you can do is receive the upload file, load it into an Image and check the dimensions. If necessary, you can then rescale it (Google will help you there), or reject it so the user uploads another.

   }
   protected void Button2_Click(object sender, EventArgs e)
   {
       if (FileUpload1.HasFile)
       {
           string fileName = Server.HtmlEncode(FileUpload1.FileName);
           string extension = System.IO.Path.GetExtension(fileName);
           System.Drawing.Image image_file = System.Drawing.Image.FromStream(FileUpload1.PostedFile.InputStream);
           int image_height = image_file.Height;
           int image_width = image_file.Width;
           int max_height = 150;
           int max_width = 150;

           image_height = (image_height * max_width) / image_width;
           image_width = max_width;

           if (image_height > max_height)
           {
               image_width = (image_width * max_height) / image_height;
               image_height = max_height;
           }

           Bitmap bitmap_file = new Bitmap(image_file, image_width, image_height);
           System.IO.MemoryStream stream = new System.IO.MemoryStream();
           string filename = Path.GetFileName(FileUpload1.PostedFile.FileName);
           bitmap_file.Save(Server.MapPath("~/uploadimage/" + filename));



           SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["dbconnection"].ToString());
           con.Open();
           string query = "INSERT INTO cpu (image) VALUES filename;
           SqlCommand cmd = new SqlCommand(query, con);
           cmd.ExecuteNonQuery();
