返回键用的ModelState错误列表 [英] Returning a list of keys with ModelState errors

问题描述

我想回有针对他们的错误的所有键的列表/数组。我试图做ModelState.ToList（项目=> item.Value.Errors.Count> 0），但它说我不能有那种前pression出于某种原因。

的

感谢

解决方案

  VAR错误的ModelState中=在ModelState.AsQueryable（）式（F =方式＆gt; f.Value.Errors。计数大于0）选择新的{标题= modelstate.Key};
 

I would like to return a list/array of all keys that have an error against them. I have tried to do ModelState.ToList(item => item.Value.Errors.Count>0) but it says I can't have that sort of expression for some reason.

Thanks

解决方案

var errors = from modelstate in ModelState.AsQueryable().Where(f => f.Value.Errors.Count > 0) select new  {  Title = modelstate.Key  };
