How to concatenate MVC6 HtmlString

Question

Similar to the old MvcHtmlString, I want to concatenate several instances HtmlString in MV6.

There doesn't seem to be an obvious way?

Perhaps the absence of such means I'm doing it wrong? The use case is I have the results of two TagBuilder instances that I want to concatenate as siblings before consuming inside of a TagHelper.

Answer 1

Taking the same path as the answer for concatenating an MvcHtmlString, I made an extension to concat a plain string and also n number of HtmlString

public static class HtmlStringExtensions
{
    public static HtmlString Concat(this HtmlString first, string plainString)
    {
        return Concat(first, new HtmlString(plainString));
    }

    public static HtmlString Concat(this HtmlString first, params HtmlString[] htmlStringsForConcat)
    {
        var sb = new StringBuilder();
        sb.Append(first);
        foreach (var htmlString in htmlStringsForConcat)
        {
            sb.Append(htmlString);
        }
        return new HtmlString(sb.ToString());
    }
}
