Question

C# 操作 PICTUREBOX里面的图片

Bitmap board = new Bitmap(pbox.Width,pbox.Height);

this.pbox.Image = board;
为什么这样写出来的Bitmap比picturebox控件大很多呢，求高手指点如何将bitmap刚好适应picturebox的尺寸

Answer 1

设置图片的图片大小模式就可以了
pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;

Answer 2

要让你的控件去适应你打开的图像的尺寸才行

Answer 3

this.pictureBox1.SizeMode = System.Windows.Forms.PictureBoxSizeMode.Zoom;
