c# - InvalidOperationException调用ResourceManager.GetString时

我的应用程序偶尔会引发异常:



这是stacktrace

    Exception type: InvalidOperationException
    Exception message: Collection was modified; enumeration operation may not execute.
   at System.Reflection.RuntimeAssembly._nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, RuntimeAssembly locationHint, StackCrawlMark& stackMark, IntPtr pPrivHostBinder, Boolean throwOnFileNotFound, Boolean forIntrospection, Boolean suppressSecurityChecks)
   at System.Reflection.RuntimeAssembly.InternalGetSatelliteAssembly(String name, CultureInfo culture, Version version, Boolean throwOnFileNotFound, StackCrawlMark& stackMark)
   at System.Resources.ManifestBasedResourceGroveler.GetSatelliteAssembly(CultureInfo lookForCulture, StackCrawlMark& stackMark)
   at System.Resources.ManifestBasedResourceGroveler.GrovelForResourceSet(CultureInfo culture, Dictionary`2 localResourceSets, Boolean tryParents, Boolean createIfNotExists, StackCrawlMark& stackMark)
   at System.Resources.ResourceManager.InternalGetResourceSet(CultureInfo requestedCulture, Boolean createIfNotExists, Boolean tryParents, StackCrawlMark& stackMark)
   at System.Resources.ResourceManager.InternalGetResourceSet(CultureInfo culture, Boolean createIfNotExists, Boolean tryParents)
   at System.Resources.ResourceManager.GetString(String name, CultureInfo culture)

这是我的代码:

public IList<Function> MapWithLanguage(IList<Function> list)
{
    if (list == null)
    {
        return null;
    }
    var currentResource = Type.GetType("Fanex.Athena.Models.ViewModel.Menu, Fanex.Athena.Models");
    ResourceManager rm = new ResourceManager(currentResource);
    var newList = new List<Function>();
    foreach (var func in list)
    {
        newList.Add(new Function
        {
            Name = rm.GetString("Menu_" + func.FunctionId),
        });
    }
    return newList;
}

有人可以帮忙吗？太奇怪了!

最佳答案

经过长时间的检查，我找到了根本原因。
这是我的代码导致上述问题:

AppDomain.CurrentDomain.GetAssemblies().

因为此方法尝试加载生成的程序集，例如“web_adg_gfgt_dfd.dll”，并且在IIS回收时可以将其删除。因此要解决此问题，我们只需要避免加载“生成的程序集”。

因此，我们有两种解决方法:

1.过滤“生成的程序集”:

AppDomain.CurrentDomain.GetAssemblies().Where(i => i.IsDynamic == false).ToList()

2.使用此方法:

BuildManager.GetReferencedAssemblies().Cast<Assembly>().ToList()
