Question

在ASP.NET MVC 5中，我使用BuildManager.GetReferencedAssemblies()方法将所有程序集获取到bin文件夹中，并在依赖项启动之前将其加载，因此可以扫描和注入所有dll。

ASP.NET Core中是否有替代方法？

https://docs.microsoft.com/en-us/dotnet/api/system.web.compilation.buildmanager.getreferencedassemblies?view=netframework-4.7.2

我尝试了这段代码，但是它开始确实给了我加载错误，例如找不到文件异常。

foreach (var compilationLibrary in deps.CompileLibraries)
{
    foreach (var resolveReferencePath in compilationLibrary.ResolveReferencePaths())
    {
        Console.WriteLine($"\t\tReference path: {resolveReferencePath}");
        dlls.Add(resolveReferencePath);
    }
}
dlls = dlls.Distinct().ToList();
var infolder = dlls.Where(x => x.Contains(Directory.GetCurrentDirectory())).ToList();
foreach (var item in infolder)
{
    try
    {
        Assembly.LoadFile(item);
    }
    catch (System.IO.FileLoadException loadEx)
    {

    } // The Assembly has already been loaded.
    catch (BadImageFormatException imgEx)
    {

    } // If a BadImageFormatException exception is thrown, the file is not an assembly.
    catch (Exception ex)
    {

    }
}

我设法创建了一个解决方案，但是我不确定它是否能解决所有情况。

最大的不同是从Assembly.LoadFile到AssemblyLoadContext.Default.LoadFromAssemblyPath的更改

        var dlls = DependencyContext.Default.CompileLibraries
            .SelectMany(x => x.ResolveReferencePaths())
            .Distinct()
            .Where(x => x.Contains(Directory.GetCurrentDirectory()))
            .ToList();
        foreach (var item in dlls)
        {
            try
            {
                AssemblyLoadContext.Default.LoadFromAssemblyPath(item);
            }
            catch (System.IO.FileLoadException loadEx)
            {
            } // The Assembly has already been loaded.
            catch (BadImageFormatException imgEx)
            {
            } // If a BadImageFormatException exception is thrown, the file is not an assembly.
            catch (Exception ex)
            {
            }
        }

ASP.NET Core中是否有BuildManager.GetReferencedAssemblies（）的替代方法？
