为 PictureBox 打开图像 - C#

Question

我不知道这里出了什么问题！它会打开 "OpenFileDialog"，它会在 PictureBox 中加载图像，但图像不会被拉伸。请帮忙！谢谢:)

    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);
        }
    }

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

PictureBox.SizeMode = PictureBoxSizeMode.StretchImage;
