How to return HTML from ASP.NET MVC Web API controller?

I tried the code below but got compile error since Response.Write is not defined:

public clas

ASP.NET Core. Approach 1

If your Controller extends ControllerBase or Controller you can use Content(...) method:

[HttpGet]
public ContentResult Index() 
{
    return base.Content("
Hello
", "text/html");
}

ASP.NET Core. Approach 2

If you choose not to extend from Controller classes, you can create new ContentResult:

[HttpGet]
public ContentResult Index() 
{
    return new ContentResult 
    {
        ContentType = "text/html",
        Content = "
Hello World
"
    };
}

Legacy ASP.NET MVC Web API

Return string content with media type text/html:

public HttpResponseMessage Get()
{
    var response = new HttpResponseMessage();
    response.Content = new StringContent("
Hello World
");
    response.Content.Headers.ContentType = new MediaTypeHeaderValue("text/html");
    return response;
}
