Question

hi,

by using below this code

 if (FileUpload1.HasFile)

                {

                    string savePath = Server.MapPath("~/memberspic/");

                    string fileName = FileUpload1.FileName;

                    string pathToCheck = savePath + fileName;

                    Random rm = new Random();

                    TextBox txtpass = new TextBox();

                    txtpass.Text = rm.Next(257871, 498371).ToString();

                    Guid g = Guid.NewGuid();

                    string extension = Path.GetExtension(FileUpload1.PostedFile.FileName);

                  

                    FileUpload1.SaveAs(Server.MapPath("~/memberspic/") + "img_pk" + txtpass.Text.ToString() + extension);

                    string te;

                    te = "~/memberspic/" + "img_pk" + txtpass.Text.ToString() + extension;

                    impath = pathToCheck;

                    cmd.Parameters.AddWithValue("@ProfilePicture", te);

                  

                }

we can save the image files in folder with this path like ~/memberspic/img_pk368811.jpg but the file size is very large.

how to compress that image file before save to folder.

please help me

it's very important to me.
