.csproj multiple hint paths for an assembly
提问by japreiss
I'm packaging example code for an SDK distribution. In the distribution, the relative path from code to the SDK assemblies is different from the build machine. For example:
我正在为 SDK 发行版打包示例代码。在发行版中，从代码到 SDK 程序集的相对路径与构建机器不同。例如：
Distribution
分配
csharp/bin/assembly.dll
example/ex1/ex1.csproj
Build Machine
构建机器
foo/sdk/csharp/bin/assembly.dll
bar/baz/quux/ex1/ex1.csproj
Assume that I can't move anything. Is there a way I can instruct ex1.csprojto look in both
假设我不能移动任何东西。有没有一种方法可以指示我同时ex1.csproj查看两者
../../csharp/bin/and../../../../foo/sdk/csharp/bin/for assembly.dll?
../../csharp/bin/并../../../../foo/sdk/csharp/bin/为assembly.dll？
In C++ I'd put the dependency path in a standalone property sheet and distribute a different version with the SDK. But C# doesn't have property sheets, and I don't want to maintain two versions of the full project.
在 C++ 中，我将依赖路径放在一个独立的属性表中，并使用 SDK 分发不同的版本。但是C#没有属性表，我不想维护完整项目的两个版本。
I've seen this questionwhich states that I can't use multiple <HintPath>tags, so I'm looking for another way to approximate the same behavior.
我见过这个问题，它指出我不能使用多个<HintPath>标签，所以我正在寻找另一种方法来近似相同的行为。

I found a hacky solution that works for my case, where the parent directory is guaranteed to be different somewhere up the tree:
我找到了一个适用于我的案例的 hacky 解决方案，其中父目录保证在树上的某个地方是不同的：
<Choose>
<When Condition="Exists('$(MSBuildProjectDirectory)\..\..\example')">
<ItemGroup>
<Reference Include="Assembly ...">
<HintPath>..\..\csharp\bin\assembly.dll</HintPath>
</Reference>
</ItemGroup>
</When>
<Otherwise>
<ItemGroup>
<Reference Include="Assembly ...">
<HintPath>..\..\..\..\..\foo\sdk\csharp\bin\assembly.dll</HintPath>
</Reference>
</ItemGroup>
</Otherwise>
</Choose>

You could subst the /csharp/binfolder into a drive (differently on each machine), for example X:and then reference X:\or X:\binon both machines, as the path will now be the same.
例如，您可以将/csharp/bin文件夹添加到驱动器中（在每台机器上不同），X:然后引用X:\或X:\bin在两台机器上，因为路径现在将相同。

Add the secondary path as follows to the general property group. in the csproj file
将辅助路径如下添加到常规属性组。在 csproj 文件中
<PropertyGroup>
<ReferencePath>..\..\..\..\..\foo\sdk\csharp\bin\</ReferencePath>
...
</PropertyGroup>
The ReferencePathproperty is intended to be specified when executing MsBuild, but it will work fine like this.
该ReferencePath属性旨在在执行 MsBuild 时指定，但它会像这样正常工作。

Simply add the build server location of the DLLs as a Reference path on the project. Seems to do the trick nicely and is very simple. Works only if you know the build server's folder of the DLLs.
只需将 DLL 的构建服务器位置添加为项目上的参考路径。似乎很好地完成了这个技巧，而且非常简单。仅当您知道 DLL 的构建服务器文件夹时才有效。

The simplest way since only ONE HintPath can be used is to use the all-so-nice Condition attribute like this:
由于只能使用 ONE HintPath，最简单的方法是使用非常好的 Condition 属性，如下所示：
<Reference Include="TheAssembly">
<HintPath Condition="Exists('..\My\Assembly\Path')">..\My\Assembly\Path\TheAssembly.dll</HintPath>
<HintPath Condition="Exists('..\..\My\Assembly\Path')">..\..\My\Assembly\Path\TheAssembly.dll</HintPath>
<HintPath Condition="Exists('..\..\..\My\Assembly\Path')">..\..\..\My\Assembly\Path\TheAssembly.dll</HintPath>
<HintPath Condition="Exists('..\..\..\..\My\Assembly\Path')">..\..\..\..\My\Assembly\Path\TheAssembly.dll</HintPath>
<HintPath Condition="Exists('..\..\..\..\..\My\Assembly\Path')">..\..\..\..\..\My\Assembly\Path\TheAssembly.dll</HintPath>
<HintPath Condition="Exists('..\..\..\..\..\..\My\Assembly\Path')">..\..\..\..\..\..\My\Assembly\Path\TheAssembly.dll</HintPath>
<HintPath Condition="Exists('..\..\..\..\..\..\..\My\Assembly\Path')">..\..\..\..\..\..\..\My\Assembly\Path\TheAssembly.dll</HintPath>
etc...
</Reference>
So the answer to the question would be this:
所以这个问题的答案是这样的：
<Reference Include="assembly">
<HintPath Condition="Exists('..\..\csharp\bin')">..\..\csharp\bin\assembly.dll</HintPath>
<HintPath Condition="Exists('..\..\..\..\foo\sdk\csharp\bin')">..\..\..\..\foo\sdk\csharp\bin\assembly.dll</HintPath>
</Reference>
If multiple conditions matches, the last one will be used.
如果多个条件匹配，将使用最后一个。

I am using this solution without any problem:
我使用这个解决方案没有任何问题：
<Reference Include="log4net">
<HintPath>
$(SolutionDir)packages\log4net.2.0.8\lib\net45-full\log4net.dll
</HintPath>
</Reference>
