我在这里有点困惑。我收到了这个异常,它告诉我这个密钥不存在。当我在监视窗口中查看字典中的所有键/值对时,有问题的键就在那里!!!我不认为我会发疯,但我可能会发疯。我在这里错过了什么吗?这是代码:
public static List<Quote> GetQuoteHistory(int id)
{
List<Quote> quotes = DataAccess.GetQuoteHistory(id);
SetAckCodeDescriptions(quotes);
return quotes;
}
private static void SetAckCodeDescriptions(IEnumerable<Quote> quotes)
{
Dictionary<string, string> ackData = GetAcknowlegementData();
foreach (Quote quote in quotes)
{
quote.AckCodes = GetAckCodeHtml(quote.AckCodes, ackData);
}
}
private static string GetAckCodeHtml(string ackCodes, IDictionary<string, string> ackData)
{
string[] codes = ackCodes.Split(',');
string html = string.Empty;
foreach (string code in codes)
{
html += string.Format("<div title='#= {0} #'>#= {1} #</div>, ", ackData[code], code);
}
return html.TrimEnd(new []{',', ' '}); // remove extra comma and space
}
更新:
public static Dictionary<string, string> GetAcknowlegementData()
{
List<AckData> list = DataAccess.GetAcknowlegementData();
return list.ToDictionary(o => o.AcknowledgementCode, o => o.Description);
}
