Displaying HTML String from Model in MVC Razor Vie

问题:

I have a Model filed that returns an HTML string with line break BR tag, but How do I display that HTML on the browser ? The problem ins instead putting the line break, the Tag itself displaying on the UI

I tried to put the model within Html.Raw(modelItem => item.Speaking), but it never works as it expecting a string inside, and Cannot convert lambda expression to type 'string' because it is not a delegate type

Below is the code and comments what I've tried.

<div>
  @{          
     string strTest = "<br/>Line 1 <br/> Line 2<br>";
     @Html.Raw(strTest); //This works and display as expected
     @MvcHtmlString.Create(strTest); //This works and display as expected       

     @Html.Raw(Html.DisplayFor(modelItem => item.Speaking)); //This doesn't work, its show the <br />  on the screen     
     @MvcHtmlString.Create(Html.DisplayFor(modelItem => item.Speaking).ToString());   //This doent work, its show the <br />  on the screen  
     @Html.Raw(modelItem => item.Speaking) //This throw error Cannot convert lambda expression to type string                                     
    }

 </div>

Appreciate any help or suggestions. thanks in advance!

Try this :

@(new HtmlString(stringWithMarkup))

and you can create a HTML helper too!:

@helper RawText(string s) {
    @(new HtmlString(s))
}

In MVC4

Instead of using @Html.Raw(modelItem => item.Speaking)

You can use @Html.Raw(@Model.Speaking.ToString())

It works for me and I hope this help someone else too

You can just omit both DisplayFor and modelItem =>, so:

@Html.Raw(item.Speaking)
