将XAML代码转换为C＃隐藏代码
这是XAML代码：

这是所有代码。
我想用许多图片制作3D立方体，这个程序只是使用图片来构建它。我想在文件中使用图片，并根据图片的数量来创建立方体。
在我使用了Colon Smith的代码后，我发现在Xaml中这个代码非常好的问题，下面的图片将显示结果。 enter image description here 但是当我使用C＃时，运行此代码时出现问题。enter image description here
问题是无效的URI。

答案 0 :(得分：1)
这样的事情：
GeometryModel3D model3d = new GeometryModel3D(); // you will already have created this...just use the reference to your own "GeometryModel3D" object
BitmapImage bitmapimage = new BitmapImage(new Uri(@"E:\2.jpg"));
Brush brush = new ImageBrush(bitmapimage);
model3d.Material = new DiffuseMaterial(brush);
或者这个：
BitmapImage bitmapimage = new BitmapImage(new Uri(@"S:\2.jpg"));
Brush brush = new ImageBrush(bitmapimage);
Geometry3D mesh = new MeshGeometry3D();
Model3DGroup group = new Model3DGroup();
GeometryModel3D mGeometry = new GeometryModel3D(mesh, new DiffuseMaterial(brush));
mGeometry.Transform = new Transform3DGroup();
group.Children.Add(mGeometry);
这将向您展示如何在XAML或代码隐藏中完成所有操作。你可以用不同的方式建立立方体，例如可以创造相同的面部4次，每次旋转90度...然后创建2个端面......但是......我认为为了清晰起见，以这种自然的方式做到这一点更简单。
