自定义标签助手不起作用

我遵循了一些有关为ASP Core创建自定义标签帮助程序的指南.

I followed a few guides on creating a custom tag helper for ASP Core.

这是我的助手:

using Microsoft.AspNetCore.Mvc.ViewFeatures; using Microsoft.AspNetCore.Razor.TagHelpers; using System; namespace ToolControlSystem.TagHelpers { [HtmlTargetElement("description", Attributes = DescriptionAttributeName, TagStructure = TagStructure.NormalOrSelfClosing)] public class DescriptionTagHelper : TagHelper { private const string DescriptionAttributeName = "asp-for"; [HtmlAttributeName(DescriptionAttributeName)] public ModelExpression Model { get; set; } public override void Process(TagHelperContext context, TagHelperOutput output) { base.Process(context, output); var description = GetDescription(Model.ModelExplorer); output.TagName = "span"; output.TagMode = TagMode.StartTagAndEndTag; output.Content.SetContent(description); } private string GetDescription(ModelExplorer modelExplorer) { string description; description = modelExplorer.Metadata.Placeholder; if (String.IsNullOrWhiteSpace(description)) { description = modelExplorer.Metadata.Description; } return description; } } }

我将其放置在_ViewImports.cshtml中:@addTagHelper *, ToolConstrolSystem.TagHelpers

Annnndd ...没事.没有智能，没有标签替换...

Annnndd... nothing. No intellisense, no tag replacing...

有什么想法吗?

推荐答案

您只需要在视图导入文件中提供程序集名称.

You need to provide only assembly name in the view imports file.

_ViewImports.cshtml:  @addTagHelper *, ToolConstrolSystem
