C#存图片
一个WinForm，有一个按钮，点击下，弹出一个文件对话框和另一个Winform，
  private void Col_Click(object sender, EventArgs e)//添加模板按钮
  {
  string str = InputBox.ShowInputBox("输入模板名", string.Empty);//
  if (str.Trim() != string.Empty)
  {
  int i = 0;
  persondata.Add(new person(str));
  int j = persondata.Count - 1;
  Form2 frm = new Form2();
  frm.Show();
  frm.Text = str;
   
  OpenFileDialog ofd = new OpenFileDialog();
  //ofd.Multiselect = true;
  if (ofd.ShowDialog() == DialogResult.OK)
  {

  bmp = (Bitmap)Image.FromStream(GetImgStream(ofd.FileName));
  image = new Emgu.CV.Image<Bgr, Byte>(bmp);
  sbmp = new Bitmap(128, 128, System.Drawing.Imaging.PixelFormat.Format24bppRgb);
  norm = new Emgu.CV.Image<Gray, Byte>(sbmp);
  int x = HJFace.FaceLocated(image.Ptr, norm.Ptr, persondata[j].Pfeature[0], 0);
  isface.Text = x.ToString();
  if (x == 0)
  {
  sbmp = IplImagePointerToBitmap(norm.Ptr);
  }
  else
  {
  pictureBox1.Image = null;
  }
  }
  }
   
  }

1、把bitmap传过去。
2、转成MemoryStream传过去。
