本文实例讲述了WinForm中实现picturebox自适应图片大小的方法。分享给大家供大家参考,具体如下:
picturebox控件共有两种载入图片方式,分别为:
pictureBox1.BackgroundImage = Image
,pictureBox1.load(url)
为使加载的图片自使用控件尺寸,可以分别对pictureBox控件设置BackGroundImageLayout=Stretch
,SizeMode=StretchImagewinform
中picturebox自适应图片大小
做了一个示例,代码如下,后面附完整项目源码下载:

//PictureBox 中的图像被拉伸或收缩,以适应PictureBox的大小。 by 何问起

{
//调整PictureBox的大小,使其等于所包含图像的大小 by 何问起
pictureBox_HoverTree.SizeMode = PictureBoxSizeMode.AutoSize;
}
}
