在后面的视图代码中，我需要将第243行的“foreach”循环替换为只返回一次发货日期，运营商和跟踪号码的内容。目前，该代码返回每个Spipment包的发货日期，运营商和跟踪号。因此，如果我有3个包，每行返回每行相同信息的3倍。 我希望每个出货包装一次显示它们。
我正在尝试通过处理这个已经开发的项目来学习ASP和MVC。 如果您需要更多信息，请与我们联系。

答案 0 :(得分：2)
替换foreach循环块：
@foreach (var shipmentPackage in Model.CustomerOrder.ShipmentPackages)
{
...
}
使用：
var shipmentPackage = Model.CustomerOrder.ShipmentPackages.FirstOrDefault();
if (null != shipmentPackage)
{
...
}
希望有所帮助。
