4的新版本里，在product增加了新字段price，请问如何在List.cshtml 页面中调取？

回复 1楼netxm的帖子

@foreach (var item in Html.InfoDataList(new{Table="product"}))
{
....
<span>@item.Price</span>
}

复制代码

字段第一个字母要大写

“....”
的内容能一并列出吗？我想调用产品名称时与价格一起展示出来

这个只是演示数据怎么调，页面数据和内容怎么排版你要自己写html部分
调字段格式就是@item.字段，字段一个字母大写就可以调出来。

我现在能调用了，但对应不了一产品一价格，即全部价格都会列出。如何调整呢？

                <div class="Price">
                      @foreach (var item in Html.InfoDataList(new{Table="product"}))
                      {
                       string url = Html.InfoDataUrl((int)item.ColumnId, (int)item.Id);
                       string Price = item.Price;
                    <div class="price">产品价格</div>
                      <span>@item.Price</span>
                        }
                </div>

人家版主意思是模板中你只调用@item.Price 这句就可以调出价格了，不是让你所有的复制进去，人才

因为不懂，所以要问，我只想知道我在product/Detail.cshtml 这文件中调用产品名称时，如何同时调用对应的价格（后台新添加了字段）

Detail.cshtml 内容发出来
