虽然我用Google搜索但是遗憾的是未能找到帮助。此 Code Project Tutorial 也是没能为我提供我真正需要的东西。
Though I googled enough but unfortunately failed to find a help. This Code Project Tutorial also failed to serve me what I actually need.
我在WinForm中有一个Image和9个PictureBox。
I have an Image and 9 PictureBox(s) in a WinForm.
Image img = Image.FromFile("media\\a.png"); // a.png has 312X312 width and height
// some code help, to get
// img1, img2, img3, img4, img5, img6, img7, img8, img9
// having equal width and height
// then...
pictureBox1.Image = img1;
pictureBox2.Image = img2;
pictureBox3.Image = img3;
pictureBox4.Image = img4;
pictureBox5.Image = img5;
pictureBox6.Image = img6;
pictureBox7.Image = img7;
pictureBox8.Image = img8;
pictureBox9.Image = img9;
以下是一个示例图片:
这是一个我的Picture Puzzle类项目的一部分。我已经完成了photoshop图片,现在想要动态剪切。
This is a part of my Picture Puzzle class project. I have done with photoshop images, now want to dynamically cut.

推荐答案
首先,不使用img1,img2 ...使用大小为9的数组。然后使用这样的几个循环更容易做到这一点:
First off, instead of using img1, img2... use an array with a size of 9. Then it's much easier to do this using a couple of loops like this:
var imgarray = new Image[9];
var img = Image.FromFile("media\\a.png");
for( int i = 0; i < 3; i++){
for( int j = 0; j < 3; j++){
var index = i*3+j;
imgarray[index] = new Bitmap(104,104);
var graphics = Graphics.FromImage(imgarray[index]);
graphics.DrawImage( img, new Rectangle(0,0,104,104), new Rectangle(i*104, j*104,104,104), GraphicsUnit.Pixel);
graphics.Dispose();
}
}
然后你可以像这样填写你的方框:
Then you can fill your boxes like this:
pictureBox1.Image = imgarray[0];
pictureBox2.Image = imgarray[1];
