我想在我的列表中获得某个索引的值怎么做?我这里有一个返回游戏列表的方法:
public static List<BO.Game> GetGames()
{
List<BO.Game> listGame = new List<BO.Game>();
BO.Game game;
SqlConnection con = new SqlConnection();
try
{
con.ConnectionString = connectionString;
con.Open();
SqlCommand com = new SqlCommand();
com.Connection = con;
com.CommandType = CommandType.StoredProcedure;
com.CommandText = "GetDisplayPicOfContest";
SqlDataReader dr = com.ExecuteReader();
while (dr.Read())
{
game = new BO.Game();
game.PrizeID = Convert.ToInt32(dr["PrizeID"]);
game.Name = dr["LocationName"].ToString();
game.ImageURL = "DisplayImages/" + dr["DisplayImage"].ToString();
game.Country = dr["CountryName"].ToString();
listGame.Add(game);
}
dr.Close();
dr.Dispose();
}
catch (Exception ex)
{
throw ex;
}
finally
{
con.Close();
con.Dispose();
}
return listGame;
}
例如,我想在列表中显示第一个和第二个项目的图像网址
我可以做这样的事吗?<div id="mcont2-sub1" class="mcont-subs mcont-subs-2">
<div class="full-detais-cover2">
<a class="opac-link" href="game_details.html" ><img class="hover-img-main" src="<%=listGames[0].ImageURL;%>" /></a>
<a class="opac-link" href="game_details.html" ><div id="cover-pager2"><img src="Images/lens-full-details.png" /></div></a>
<div class="ticket-quantity2">
<span>Choose ticket quantity</span><span>Tickets $5.00</span>
<ul class="quantity-paging">
<li><a> 1 </a></li>
<li><a> 2 </a></li>
<li><a> 3 </a></li>
<li><a> 4 </a></li>
<li><a> 5 </a></li>
<li><a>10</a></li>
<li><a>15</a></li>
<li><a>20</a></li>
</ul>
</div>
</div>
<div class="descrip-place" id="id-descrip-place">
<p class="description">Marbella Beach Club Marriott</p>
<p class="place">Spain</p>
</div>
<a href="game_details.html" class="arrow-light-blue" ><img src="Images/arrow-light-blue.png" /></a>
</div>
<div id="mcont2-sub2" class="mcont-subs mcont-subs-2">
<a href="game_details.html" ><img src="<%=listGames[1].ImageURL;%>" /></a>
<div class="descrip-place" id="Div1">
<p class="description">Waiohai Beach Club Marriott</p>
<p class="place">Hawaii</p>
</div>
<a href="game_details.html" class="arrow-light-blue" ><img src="Images/arrow-light-blue.png" /></a>
</div>

我不确定您到底需要什么,但如果您想获取列表C#中某些索引的值您可以使用square brackets syntax
执行此操作:
List<something> list = GetListOfSomething();
var someItem = list[yourIndex];
您可以这样做,因为List<T>
实现了定义此索引器的IList<T>
接口:
object this[int index] { get; set; }
此外,您可以使用Linq to Objects
查询您的列表。
希望这有帮助。

我认为最简单的解决方法是替换以下代码
<img class="hover-img-main" src="<%=listGames[0].ImageURL;%>" />
使用asp.net Image Control并从代码隐藏设置其src。
