我的应用程序偶尔会抛出异常:
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.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;
}
有人能帮忙吗？太奇怪了!
最佳答案
查了半天，找到了根本原因。 这是我的代码导致上述问题的原因:
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”，并且它们可以在 IIS 回收时被删除。因此要修复它，我们只需要避免加载“生成的程序集”。
因此我们有两种修复方法:
1.过滤“生成的程序集”:
AppDomain.CurrentDomain.GetAssemblies().Where(i => i.IsDynamic == false).ToList()
2.使用这个方法:
BuildManager.GetReferencedAssemblies().Cast<Assembly>().ToList()
关于c# - InvalidOperationException 调用 ResourceManager.GetString 时，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32645007/
