InvalidOperationException 调用 ResourceManager.GetString 时 [英] InvalidOperationException When calling ResourceManager.GetString

问题描述

我的应用程序偶尔会抛出异常:

My application throw the exception occasionally:

异常类型:InvalidOperationException 异常消息:收藏被修改；枚举操作可能不会执行.

Exception type: InvalidOperationException Exception message: Collection was modified; enumeration operation may not execute.

这里是堆栈跟踪

    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?这太奇怪了！

Anybody can help?it's so weird!

推荐答案

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:

After a long time checking, I found the root cause. And here's my code cause above issue:

AppDomain.CurrentDomain.GetAssemblies().

因为这种方法尝试加载生成的程序集，例如web_adg_gfgt_dfd.dll"，并且它们可以在 IIS 回收时删除.所以要修复它，我们只需要避免加载生成的程序集".

Because this method try to load generated assemblies such as "web_adg_gfgt_dfd.dll" and they can be removed when IIS recycle .So to fix it we only need to avoid loading "generated assemblies".

因此我们有两种修复方法:

Therefore we have 2 way for fixing:

1.过滤生成的程序集":

1.Filter "generated assemblies":

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

2.使用此方法:

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