我的所有 Controller 操作都呈现良好，除了一个。
我找到了与 IIS Express 相关的其他解决方案，但这是在服务器 2012 上运行的。
这是 Controller Action :
public ActionResult Index()
{
try
{
var viewModels = GetHostInfoViewModelList();
return View(viewModels);
}
catch (Exception ex)
{
ex.ReportError();
return new HttpStatusCodeResult(404,$"{ex.Message}|{ex.InnerException}");
}
}
这是 GetHostInfoViewModelList:
public IEnumerable<ViewModelHostInfo> GetHostInfoViewModelList()
{
using (var db = new WINCMUEntities())
{
try
{
//join host info with sleep status
var sleepRecords = db.SleepTrackings.ToList();
var hostInfo = db.WINCMU_HostInfo.ToList();
var viewModels = new List<ViewModelHostInfo>();
hostInfo.ForEach(x =>
{
viewModels.Add(new ViewModelHostInfo()
{
HostName = x.HostName ?? "Not Found",
Id = x.ID,
newsystem = x.newsystem,
Zone = x.Zone ?? "Not Found",
IsSleeping = sleepRecords.FirstOrDefault(s => s.HostName.ToLower() == x.HostName.ToLower())
?.IsCurrentlySleeping ?? false,
IP_address = x.IP_address ?? "Not Found",
ReportingArea = x.ReportingArea ?? "Not Found",
agent_active = x.agent_active,
date_added = x.date_added,
is_agent = x.is_agent
});
});
return viewModels;
}
catch (Exception ex)
{
ex.ReportError();
throw;
//return new List<ViewModelHostInfo>();
}
}
}
这是完整的错误文本:

最佳答案
错误消息指出在设置响应状态时发生异常:
[ArgumentOutOfRangeException: Specified argument was out of the range of valid values. Parameter name: value]
System.Web.HttpResponse.set_StatusDescription(String value) +4538824
您的代码没有为 404 状态结果设置标准描述:
return new HttpStatusCodeResult(404,$"{ex.Message}|{ex.InnerException}");
将此更改为:
return new HttpStatusCodeResult(404,"Not Found");
描述可以省略，但是如果设置了，必须和状态码匹配。
