我想在我的Visual Studio解决方案以编程方式更新项目的参考。

I wish to programatically update the references in the projects in my Visual Studio solution.

我在我的解决方案大约15个项目，当我开发/调试我想引用指向解决方案中的项目。

I have roughly 15 projects in my solution and when I am developing/debugging I want the references to point to the projects within the solution.

由于我的释放过程的一部分，我有时需要做一个项目的副本，然后更新引用指向内置的dll在某个文件夹中。

As part of my release procedure I sometimes need to make a copy of one project and then update the references to point to built dlls in a certain folder.

我可以计算出项目文件的结构和引用如何在他们的工作，我想建立一个命令行工具来分析项目文件，并根据需要更改引用。

I can work out the structure of the project files and how references work within them and I am thinking of building a command line tool to parse the project files and change references as required.

我的问题是： 1.这听起来一个明智的做法 2.有这个人的经验和/或如何做他们处理开发和释放模式之间切换 3，没有人有处理解析的Visual Studio项目文件的库。

My questions are: 1. Does this sound a sensible thing to do 2. Has anyone experience of this and/or how do they handle switching between developing and release modes 3. Does anyone have any libraries that deal with parsing Visual Studio project files.

澄清：

感谢您的答复。也许我要澄清，我想用这几个情况。

Thanks for the responses. Perhaps I should clarify a few situations where I wish to use this.

一）我的应用程序包含15个项目。我尽量保持该解决方案尽可能小的什么，我的工作，所以说我有5个项目在我的解决方案。我现在需要调试/开发没有解决，所以我加入这个项目的项目之一，但我必须： - 设置在原项目中引用指向项目引用，而不是编译的DLL - 改变中新加入的项目引用指向相应的项目引用

a) My application contain 15 projects. I try and keep the solution as small as possible for what I am working on, so say I have 5 projects in my solution. I now need to debug/develop one of the projects not in the solution so I add this project but I have to: - set the references in the original projects to point to project references rather than compiled dlls - change the references in the newly added project to point to the appropriate project references

我想我的工具自动做到这一点，只有这样，我知道所以这在present操纵项目文件

I would like my tool to do this automatically and the only way I know to so this at present is manipulating the project files

b）作为一个服务包构建过程我把其中一个项目的副本，进行必要的code的变化，并建立使用Visual Studio的一部分。要做到这一点，我不得不改变所有引用到编译的DLL

b) As part of a service pack build procedure I take a copy of one of the projects, make the necessary code changes and build using Visual Studio. To do this I have to change all the references to the compiled dlls

推荐答案

我想一个更好的办法，这将是对直接在项目文件中的引用使用条件块。然后，所有你需要做的MSBuild的释放建设，它会选择正确的引用中设置一个特定的标志。

I think a better approach to this would be to use Conditional blocks on your references inside the project file directly. Then all you need to do is set a particular flag during the msbuild for the "release" build and it will pick up the correct references.

例如

<ItemGroup Condition="'$(IsRelease)'=='True'">
  <Reference Include="..." />
</ItemGroup>
<ItemGroup Condition="'$(IsRelease)'!='True'">
  <Reference Include="..." />
</ItemGroup>
