先上代码

需要继承WebViewPage 或 WebViewPage<T>

using System.Web.Mvc;

namespace Library
{
    public abstract class Library : WebViewPage
    {
        public HtmlHelper Fish { get; set; }
        public override void InitHelpers()
        {
            base.InitHelpers();
            Fish = new HtmlHelper(ViewContext, this);
        }
    }
    public abstract class Library<TModel> : WebViewPage
    {
        public HtmlHelper<TModel> Fish { get; set; }
        private ViewDataDictionary<TModel> _viewData;

        public override void InitHelpers()
        {
            base.InitHelpers();
            Fish = new HtmlHelper<TModel>(ViewContext, this);
        }
        protected override void SetViewData(ViewDataDictionary viewData)
        {
            _viewData = new ViewDataDictionary<TModel>(viewData);
            base.SetViewData(_viewData);
        }
        public new TModel Model
        {
            get
            {
                return ViewData.Model;
            }
        }
        public new ViewDataDictionary<TModel> ViewData
        {
            get
            {
                if (_viewData == null)
                {
                    SetViewData(new ViewDataDictionary<TModel>());
                }
                return _viewData;
            }
            set
            {
                SetViewData(value);
            }
        }
    }
}

mvc页面使用方法

@inherits Library.Library<object>


@Fish.TextBox("text")
