using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Linq.Expressions;using System.Web.Mvc;using System.Text;namespace MyJob.Helpers{    public static class HtmlHelperExt    {        public static MvcHtmlString RadioButtonList(this HtmlHelper helper, string name, IEnumerable
     
       items,string selectValue=null,RadioButtonListType type=0)        {            var selectList = new SelectList(items);            return helper.RadioButtonList(name, selectList, selectValue,type);        }           ///

       ", name, rbId, rbValue);                    else                        radioTag = String.Format("
       ", name, rbId, rbValue);                }                else {                    if (rbValue.Trim() == selectValue.Trim())                         radioTag = String.Format("
       ", name, rbId, rbValue);                    else                        radioTag = String.Format("

");            }            return MvcHtmlString.Create(sb.ToString());               }    }}

调用1

@Html.RadioButtonList(m=>m.UserType,new [] {    new SelectListItem {          Text = "个人",           Value = "Personal",           Selected = true     },      new SelectListItem {            Text = "企业",            Value = "Company"      }})

调用2　　

@Html.RadioButtonList(m=>m.UserType,new [] {    new SelectListItem {          Text = "个人",           Value = "Personal",           Selected = true     },      new SelectListItem {            Text = "企业",            Value = "Company"      }},"个人",0)

其实复选也一样！ checkBoxlist
