下拉列表viewdata？

Question

我有一个名为product的集合，它有两个字段Id和Name。

创建下拉列表我正在使用

ViewData["Geography"] = new SelectList( parent,"Id","Id");

我想在下拉列表中显示Id + Name。

我尝试了一些不起作用的东西

ViewData["Geography"] = new SelectList( parentCollection,"Id","Id Name");

ViewData["Geography"] = new SelectList( parentCollection,"Id","Id" + "Name");

Answer 1

从parentCollection查询并使用select new

创建新媒体资源

ViewData["Geography"] = 
    new SelectList((from s in parentCollection select new { 
        ID = s.Id,
        IdAndName = s.Id + " " + s.Name}), 
       "ID", 
       "IdAndName", 
        null);
