相同的DLL，两个不同的版本 [英] Same DLLs two different versions

问题描述

我有两个不同的项目，都使用NuGet的Newtonsoft.Json.

I have two different projects and both use Newtonsoft.Json from NuGet.

• 项目A使用版本9.0.1.
• 项目B使用版本11.0.1.

在构建项目时，一个dll会覆盖另一个dll，因为它们都被编译在同一个文件夹中.

When building the projects, one dll is overwriting the other dll, because they are both being compiled in the same folder.

如何将dll的编译重定向到单独的文件中，又如何说Project A使用9.0.1，Project B使用11.0.1?

How can I redirect the compilation for the dll's in seperate files and how can I say that Project A uses 9.0.1 and Project B uses 11.0.1?

最好有一个文件夹"Newtonsoft"，并且有2个文件夹"11"和"9".在这些文件夹中是特定版本.(如果还有其他解决方案，那么我也可以与其他解决方案配合使用.)

It would be great to have a folder "Newtonsoft" and there are 2 folders "11" and "9". In those folders are the specific versions. (If there's another solution, then I'm also fine with the other one).

项目A和项目B都是插件"，我的应用程序正在使用它们，其中包括来自Plugin-Folder的那些插件.这意味着我当前有一个使用以下dll的应用程序(它们是全部放在一个文件夹中):

Project A and Project B are both "Plugins", which are being used by an application by me, which includes those plugins from a Plugin-Folder.. This means I currently have an application which uses the following dll's (they are all in one folder):

• Project_A.dll
• Project_B.dll
• NewtonSoft.Json.dll(9.0.1或11.0.1)

ProjectA.dll

ProjectA.dll

这是我的app.config

This is my app.config

项目A:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-11.0.0.0" newVersion="11.0.0.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="YamlDotNet" publicKeyToken="ec19458f3c15af5e" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

项目B:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-11.0.0.0" newVersion="11.0.0.0" />
        <codeBase version="11.0.0.1" href="Newtonsoft.Json.dll" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" /></startup></configuration>

推荐答案

已解决

通过执行以下操作使其正常工作:

Got it working by doing it like this:

在使用Newtonsfot.Json的任何方法/类之前，我使用以下两行:

Before I use any method/class of Newtonsfot.Json, I use the following two lines:

//The AssemblyResolve event is called when the common language runtime tries to bind to the assembly and fails.
AppDomain currentDomain = AppDomain.CurrentDomain;
currentDomain.AssemblyResolve += new ResolveEventHandler(currentDomain_AssemblyResolve);

如果应用程序抛出异常，将始终调用该事件

The event will always be called if the application would throw the exception

无法加载文件或程序集'Newtonsoft.Json，Version = 9.0.0.1，文化=中性，PublicKeyToken = 30ad4fe6b2a6aeed"或其中之一依赖关系.系统找不到指定的文件.

Could not load file or assembly 'Newtonsoft.Json, Version=9.0.0.1, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The system cannot find the file specified.

该事件因此捕获了该事件并加载了正确的dll:

The event therefore catches the event and loads the correct dll:

Assembly currentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
{
    //This handler is called only when the common language runtime tries to bind to the assembly and fails.

    //Retrieve the list of referenced assemblies in an array of AssemblyName.
    Assembly MyAssembly, objExecutingAssemblies;
    string strTempAssmbPath = "";

    objExecutingAssemblies = Assembly.GetExecutingAssembly();
    AssemblyName[] arrReferencedAssmbNames = objExecutingAssemblies.GetReferencedAssemblies();

    //Loop through the array of referenced assembly names.
    foreach (AssemblyName strAssmbName in arrReferencedAssmbNames)
    {
        //Check for the assembly names that have raised the "AssemblyResolve" event.
        if (strAssmbName.FullName.Substring(0, strAssmbName.FullName.IndexOf(",")) == args.Name.Substring(0, args.Name.IndexOf(",")))
        {
            //Build the path of the assembly from where it has to be loaded.
            //The following line is probably the only line of code in this method you may need to modify:
            strTempAssmbPath = "C:\\Program Files\\PATH TO YOUR FOLDER" + "\\Newtonsoft.Json\\9.0.1";
            if (!strTempAssmbPath.EndsWith("\\")) strTempAssmbPath += "\\";
            //strTempAssmbPath += args.Name.Substring(0, args.Name.IndexOf(",")) + ".dll";
            strTempAssmbPath += strAssmbName.Name + ".dll";
            break;
        }

    }
    //Load the assembly from the specified path.
    MyAssembly = Assembly.LoadFrom(strTempAssmbPath);

    //Return the loaded assembly.
    return MyAssembly;
}
