我对收藏品很新,所以请耐心等待我,我的行话甚至可能不准确。
我让PetaPoco将查询结果作为IEnumerable返回,每个结果都有一个集合。我想评估集合以从每个集合中的特定字段获取特定字符串。到目前为止,我能够迭代Enumerable,并且看起来能够根据我的代码片段访问一个对象,但是当我在调试中查看c.Language时,它只是字符串的第一个字符(例如,c.Language应该等于“ JPY“它仅等于”J“)
我完全错了吗?感谢您的建议public void AddContactOrder(object sender, EventArgs e)
{
IEnumerable OrderFact = new OrdersFactsController().getOrderFacts(base.ModuleId);
IEnumerator enumerator = OrderFact.GetEnumerator();
var test = "";
List<string> lang = new List<string>();
while (enumerator.MoveNext())
{
OrderFact c = (OrderFact)enumerator.Current;
if (c.Language == "JPY")
{
test = "okay";
}
}
}
getorderFacts()返回一个IEnumerable,其中T是OrderFact
public class OrderFact
{
public int ID { get; set; }
public int ModuleId { get; set; }
public string ProdCode { get; set; }
public string Language { get; set; }
public string Currency { get; set; }
public string KeyCodes { get; set; }
public string OrderSourceCode { get; set; }
public string OfferingCode { get; set; }
public string JobNumber { get; set; }
public DateTime CreatedDate { get; set; }
public DateTime ModifiedDate { get; set; }
}

你最好只使用foreach循环:
foreach (var c in new OrdersFactsController().getOrderFacts(base.ModuleID))
{
if (c.Language == "JPY")
test = "okay";
}

您可以使用System.Linq
的{{3}}:
public void AddContactOrder(object sender, EventArgs e)
{
var orderFacts = new OrdersFactsController().getOrderFacts(base.ModuleId);
var test = orderFacts.Any(x => x.Language == "JPY") ? "okay" : "";
}
答案 2 :(得分:3)
public void AddContactOrder(object sender, EventArgs e)
{
IEnumerable<OrderFact> orderFacts = new OrdersFactsController().getOrderFacts(base.ModuleId);
var test = "";
if(orderFacts.Any(x => x.Language == "JPY")) test="okay";
}
