1. 上傳圖片並 儲存到自己的路徑

        private void gtisButton1_Click(object sender, EventArgs e)
        {
            OpenFileDialog openFileDialogTemp = new OpenFileDialog();
            openFileDialogTemp.Title = "選擇要上傳的圖片";
            openFileDialogTemp.Filter = "All Files(*.*)|*.*|點陣圖(*.bmp)|*.bmp|JPEG(*.jpg)|*.jpg
 
";

            DialogResult dr = openFileDialogTemp.ShowDialog();

            textBox1.Text = openFileDialogTemp.FileName;
            if (!File.Exists(openFileDialogTemp.FileName))
            {
                MessageBox.Show("照片為空，請選擇圖片");
                return;
            }

            if (dr == DialogResult.OK)
            {
                
 
string image = openFileDialogTemp.FileName;
                string picpath = openFileDialogTemp.FileName;

                pictureBox1.Image = Image.FromFile(image);
                this.pictureBox1.Text = image;

                string id = "111";
                File.Copy(openFileDialogTemp.FileName, Application.StartupPath 
 
+ "\\Image\\" + id + ".jpg");

            }

        }
