我的应用偶尔抛出异常：
Exception type: InvalidOperationException Exception message:
Collection was modified; enumeration operation may not execute.
这是堆栈跟踪

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！
解决方法
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：
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,如“web_adg_gfgt_dfd.dll”,并且可以在IIS回收时删除它们.为了修复它,我们只需要避免加载“生成的程序集”.
1.过滤“生成的组件”：
AppDomain.CurrentDomain.GetAssemblies().Where(i => i.IsDynamic == false).ToList()
2.使用这种方法：
BuildManager.GetReferencedAssemblies().Cast<Assembly>().ToList()
