netcore LoaderException

标签： c# asp.net-core rider

我正在构建针对.NetCore20的服务。我正在CentOS 7.6上使用JetBrains Rider构建这些服务。

我的一个解决方案中有一个非常奇怪的问题，该库在许多其他解决方案中使用而没有任何问题。

屏幕截图显示了抛出的完整错误： enter image description here

因此，如果我查看我的.csproj文件，它将显示以下内容：

找不到的程序集是BediDto和BediModels，但是当然都存在，并且也在项目的bin文件夹中：

[tbednarz@linuxdev-tbws2 netcoreapp2.0]$ pwd
/home/tbednarz/Projects/BizBusInvoiceServer/BizBusInvoiceServer/bin/Debug/netcoreapp2.0
[tbednarz@linuxdev-tbws2 netcoreapp2.0]$ ls -all | grep Bedi

-rw-rw-r-- 1 tbednarz tbednarz   1096 Jun  4 16:54 BediTools.pdb

我在项目文件中不喜欢的是相对路径（.... \ BediLibs .....），这在运行时是否仍然有效，我不知道....

无论代码是在调试器中启动还是作为Docker容器启动，代码都会失败...

有什么想法吗？我是否需要手动删除某个地方的任何旧缓存文件？ 任何帮助将不胜感激。

更新

自@mythz答复以来，我有一些有关抛出该小羊膜的地方的更多详细信息。这是ServiceStack中的最后一个代码：

ServiceController.cs具有方法public ServiceController Init()，然后具有方法private List<Type> GetAssemblyTypes(Assembly[] assembliesWithServices)。在此方法内有一个循环

foreach (Assembly assembliesWithService in assembliesWithServices)
{
    str1 = assembliesWithService.FullName;
    foreach (Type type in assembliesWithService.GetTypes())
    {
        if (!this.appHost.ExcludeAutoRegisteringServiceTypes.Contains(type))
        {
            str2 = type.GetOperationName();
            typeList.Add(type);
        }
    }
}

此语句引发了我捕获的异常：

str1 = assembliesWithService.FullName;

有关详细信息，请参见屏幕截图2： enter image description here 如果进入该语句，我将使用.NET代码，名为Assembly.cs的文件，并且使用以下方法：

public virtual Type[] GetTypes()
{
  Module[] modules = this.GetModules(false);
  int length1 = 0;
  Type[][] typeArray1 = new Type[modules.Length][];
  for (int index = 0; index < typeArray1.Length; ++index)
  {
    typeArray1[index] = modules[index].GetTypes();
    length1 += typeArray1[index].Length;
  }
  int destinationIndex = 0;
  Type[] typeArray2 = new Type[length1];
  for (int index = 0; index < typeArray1.Length; ++index)
  {
    int length2 = typeArray1[index].Length;
    Array.Copy((Array) typeArray1[index], 0, (Array) typeArray2, destinationIndex, length2);
    destinationIndex += length2;
  }
  return typeArray2;
}

语句typeArray1[index] = modules[index].GetTypes();是导致崩溃的语句。在这里，我还可以看到库中的FileNotFound异常： enter image description here

所以问题是为什么会这样。我在很多其他项目中都没有问题地使用了它，所以这很奇怪，但是也许代码为.NET方面的其他开发人员提供了更深入的专业知识，使我可以进一步研究...

更新2

我将软件作为docker映像分发。为了构建它们，我目前使用一些bash脚本。这是我在“问题”解决方案中用来生成本地图像的一个图像：

#!/usr/bin/env bash
publishdir=publish
localimagename=bbinvoiceserver
if [ -d ${publishdir} ]; then
  printf "Target directory (%s) already exists, deleting it ...\n" ${publishdir}
  rm -rf ${publishdir}
fi
dotnet publish -c "Debug" -o ${publishdir}
# create docker image
docker build -t ${localimagename} -f dockerfile.debug .
if docker image ls | grep -q '<none>'; then
    printf "Removing temporary images (<none>   <none> ones)....\n"
    docker rmi $(docker images -f dangling=true -q)
fi
docker image ls
rm -rf ${publishdir}

“ dotnet publish”的输出为：

如您所见，文件BediModels.dll和BediDto.dll位于顶部。

2 个答案:

答案 0 :(得分：0)

如果这些是项目引用，则应改为引用该项目：

<ProjectReference Include="..\..\BediLibs\BediDto\BediDto.csproj" />

答案 1 :(得分：0)

我可以通过简单地将两个DLL添加到“ root”项目中来解决此问题，尽管它们并不需要直接在其中存在，现在它可以工作了。因此，遵循@mythz建议

  

但是，如果您要直接引用.dll，我建议您将它们放在本地/ lib文件夹中，并使用脚本来复制它们，而不是尝试引用项目输出文件夹。

似乎是要走的路。但是我相信这是dotnet构建工具中的某个错误，似乎不能正确地正确解决所有依赖关系（至少在某些未知情况下……）这些类型的问题通常很难找到，因为它们是几乎永远无法正确再现...
