Write the content of Html.Raw into the document

Question

I'm trying to show page errors so I have written the following code:

    <div class="errors">
        @{
        ViewData.ModelState.Values.SelectMany(v => v.Errors).ToList()
       .ForEach(e => { Html.Raw($"<span>{e.ErrorMessage}</span>"); });
        }
   </div>

The Html.Raw() does not output anything. Razor - HTML.RAW does not output text suggest writing it like @Html.Raw which in my case is not valid

@StephenMuecke this is what I have mentioned in my question. as it is inside a C# code, putting a @ won't do any good. — Ashkan Mobayen Khiabani, Jul 31 '17 at 22:29
No - you still need the leading `@` (without it it executes the method but does not write it to the response) — , Jul 31 '17 at 22:33
but didn't work with it either, that's why I asked this question — Ashkan Mobayen Khiabani, Jul 31 '17 at 22:35
The `$` in your code would throw an error :) But if your try `
@{Html.Raw("xxx");}
` your will not see any output, but if you use `
@Html.Raw("xxx")
` you will — , Jul 31 '17 at 22:47

e.ErrorMessage isn't HTML, so you must not use Html.Raw().

Instead, you should use a simple loop:

@foreach(var e in ViewData.ModelState.Values.SelectMany(v => v.Errors)) {
  <span>@e.ErrorMessage</span>
}

Very nice, it solved the problem. but still I wonder how to write the Html.Raw value (for sake of learning) – Ashkan Mobayen Khiabani Jul 31 '17 at 18:55
@AshkanMobayenKhiabani: `Html.Raw()` returns a value, which you must print on the page. You can call the `Write` methods (from the base class) directly from a lambda, but the general answer is to use `@foreach` instead of lambdas. – SLaks Jul 31 '17 at 19:01
