.net Core 中將原MVC中的 MvcHtmlString轉換

public static IHtmlContent CustomLabelFor(this IHtmlHelper helper, Expression> expression, object htmlAttributes) { string result; TagBuilder div = new TagBuilder("div"); div.MergeAttribute("class", "form-group"); var label = helper.LabelFor(expression, new { @class = "control-label col-lg-1" }); div.InnerHtml.AppendHtml(label); using (var sw = new System.IO.StringWriter()) { div.WriteTo(sw, System.Text.Encodings.Web.HtmlEncoder.Default); result = sw.ToString(); } return new HtmlString(result); }
