我认为我的linq查询没有产生任何结果,因为“Stock”对象没有被实例化。欢迎任何帮助!
在我班上:
public class Stock
{
public List<string> Names { get { return NamesList(); } }
public List<int> Prices { get { return PriceList(); } }
private List<int> PriceList()
{
Random random = new Random();
List<int> stockPriceList = new List<int>();
stockPriceList.Add(random.Next(100, 220));
stockPriceList.Add(random.Next(1000, 5365));
return stockPriceList;
}
private List<string> NamesList()
{
List<string> stockNames = new List<string>();
stockNames.Add("CBA");
stockNames.Add("ANZ");
return stockNames;
}
}
在我的数据绑定方法中。 Lync查询不会产生任何结果。
private void bindPriceList()
{
List<Stock> stockList = new List<Stock>();
rptPriceList.DataSource = stockList.Select(s => new { Name = s.Names, Price = s.Prices });
rptPriceList.DataBind();
}
答案 0 :(得分:1)
请改为尝试:
代码背后:
public partial class RepeaterExample : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if(!Page.IsPostBack)
{
this.bindPriceList();
}
}
private void bindPriceList()
{
var stock1 = new Stock { Name = "CBA", Price = "12.99" };
var stock2 = new Stock { Name = "ANZ", Price = "13.99" };
rptPriceList.DataSource = new List<Stock> { stock1, stock2 };
rptPriceList.DataBind();
}
}
public class Stock
{
public string Name { get; set; }
public string Price { get; set; }
}
