c# - DLL 重定向 - 内部版本号不匹配

Question

我似乎无法在 VS2010 ConsoleApplication 中加载 System.Net.Http.Formatting.dll，即使我已经设置了重定向。这是错误

System.IO.FileNotFoundException: Could not load file or assembly 'System.Net.Http.Formatting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

因此，据我了解，它正在寻找 System.Net.Http.Formatting，Version=4.0.0.0，但我的项目包含版本 4.0.21112.0，因此我设置了一个重定向(堆栈中也提到了这一点trace 所以我知道重定向至少被拾取了)

我的重定向是:

      <dependentAssembly>
    <assemblyIdentity name="System.Net.Http.Formatting" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.21112.0" />
  </dependentAssembly>

它在 C:/VS2010/Accman.NET/AccManBackEndLibrary/bin 中找到较新的 DLL，但提示内部版本号不正确。但是，据我所知，整个版本号都是正确的。

如果我运行 Powershell 命令来获取确切的版本号，它会返回相同的版本号:

PS F:\> (get-item C:\VS2010\Accman.NET\AccManBackEndLibrary\bin\System.Net.Http.Formatting.dll).VersionInfo

ProductVersion   FileVersion      FileName
--------------   -----------      --------
4.0.21112.0      4.0.21112.0      C:\VS2010\Accman.NET\AccManBackEndLibrary\bin\System.Net.Http.Formatting.dll

求助!我做错了什么？

谢谢

您可以从您的项目中删除 dll 引用并手动重新添加您拥有的 dll。
(Solution Explorer -> References -> Add -> Browse)
应该可以解决问题。
