出现InvalidOperationException当调用ResourceManager.GetString

问题描述

我的应用程序抛出异常偶见：

My application throw the exception occasionally:

异常类型：InvalidOperationException异常消息：
  集合被修改;枚举操作可能无法执行。

和这里的堆栈跟踪

    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code：

And here's my code:

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;
}

任何人都可以帮忙吗？它是如此不可思议！

Anybody can help?it's so weird!

推荐答案

很长一段时间检查后，我发现的根本原因。
这是我的code会导致上述问题：

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

AppDomain.CurrentDomain.GetAssemblies().

由于这种方法尝试加载生成的程序集，如web_adg_gfgt_dfd.dll，他们可以被删除当IIS回收。所以要解决这个问题，我们只需要避免加载生成的组件。

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2路固定：

Therefore we have 2 way for fixing:

1.Filter生成组件

1.Filter "generated assemblies":

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

2，采用此方法：

2.Using this method :

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