c# - 无法使用 TagBuilder 组合标签

Question

我正在尝试构建一个组合标签:

第一个标签:<span class="requiredInidicator">* </span>第二个标签:<label>SomeText</label> (为简洁起见，删除了属性)

我想将它们结合起来返回一个 MVCHtmlString，但下面的代码完全忽略了跨度。有人可以指出我做错了什么

这是我的代码:

// Create the Label
var tagBuilder = new TagBuilder("label");
tagBuilder.Attributes.Add("id", "required" + id);
//I get the id earlier fyi - not pertinent fyi for this question )

// Create the Span
var required = new TagBuilder("span");
required.AddCssClass("requiredInidicator"); 
required.SetInnerText("* ");

//Now combine the span's content with the label tag
tagBuilder.InnerHtml += required.ToString(TagRenderMode.Normal);
tagBuilder.SetInnerText(labelText);
var tag = MvcHtmlString.Create(tagBuilder.ToString(TagRenderMode.Normal));
return tag;

创建标签时，span 会被完全忽略。当我在调试期间检查标签时，它不关心我通过 .InnerHtml+= 附加的要求

有什么明显的我做错了吗？

像这样尝试:

var label = new TagBuilder("label");
label.Attributes.Add("id", "required" + id);
//I get the id earlier fyi - not pertinent fyi for this question )

// Create the Span
var span = new TagBuilder("span");
span.AddCssClass("requiredInidicator");
span.SetInnerText("* ");

//Now combine the span's content with the label tag
label.InnerHtml = span.ToString(TagRenderMode.Normal) + htmlHelper.Encode(labelText);
return MvcHtmlString.Create(label.ToString(TagRenderMode.Normal));
