如何在C#项目中使用VS2012的自动HLSL编译? [英] How can I use VS2012's automatic HLSL compiling in a C# project?
问题描述
http://blogs.msdn.com /b/chuckw/archive/2012/05/07/hlsl-fxc-and-d3dcompile.aspx
上面的链接指出注意:此自动集成仅适用于C ++项目，不适用于C#项目.".我正在使用SlimDX，并且肯定有一种方法可以使Visual Studio在C#项目中的构建时编译HLSL着色器?
The above link states that "Note: This automatic integration only works for C++ projects, not C# projects.". I'm using SlimDX and surely there's a way to make it so Visual Studio will compile HLSL shaders at build time in C# projects?
推荐答案
我认为您会发现这可能对您有用.
I think you will find this might do it for you.
您必须在bin文件夹中具有fxc.exe DirectX编译器，它可以 可以在直接的x sdk中找到.
You must have the fxc.exe directx compiler in the bin folder, it can be found in the direct x sdk.
此类提供可在WPF中使用的可观察集合. 显示着色器配置文件列表.
This class provides an observable collection that can be used in WPF to show the list of shader profiles.

这是另一个有用的资源:
This is another useful resource:
它显示了如何在System.Windows.Media.Effects Namespace
他提到public class EffectCompiler
http://msdn.microsoft.com /library/windows/desktop/bb232919(v=vs.85).aspx
请包括
using System.IO;
之前
using System.Windows.Shapes;
它会引发错误，但是会按此顺序工作，并发出警告，但仍会编译.在两个名称空间中都使用Path会产生歧义.
It throws an error, but it will work in this order, with a warning, it still compiles. There is ambiguity using Path with both namespaces.
请告知这是否可以解决您的问题.
Please advise if this solves your problem.
