PictureBox打開圖片 - C＃

Question

我不知道這裏有什麼問題！它打開一個「OpenFileDialog」，它在圖片框中加載圖像，但圖像沒有被拉伸。請幫忙！謝謝:)

private void browsePic_Click(object sender, EventArgs e) 
    { 
     openPicture.Filter = "PNG|*.png|JPG|*.jpg;*.jpeg"; 
     if(openPicture.ShowDialog() == DialogResult.OK) 
     { 
      pictureBox2.BackgroundImageLayout = ImageLayout.Stretch; 
      pictureBox2.Image = new Bitmap(openPicture.FileName); 
     } 
    }

根據需要更改PictureBox的SizeMode屬性。 https://msdn.microsoft.com/de-de/library/system.windows.forms.picturebox.sizemode(v=vs.110).aspx

PictureBox.SizeMode = PictureBoxSizeMode.StretchImage;
