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.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()
这篇关于出现InvalidOperationException当调用ResourceManager.GetString的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
