当我尝试在我的 Web 应用程序上运行报告时,我收到此错误:
“/Revenue”应用程序中的服务器错误。
输入字符串的格式不正确。

文件中的代码如下所示:
var ans = from a in analytics.Rows.Cast<DataRow>()
group a by a["LineTitle"] into g
select new
{
Name = g.Key.ToString(),
SalesPersonStats = g.Key.ToString().Contains(SP.FullName),
Value = g.FirstOrDefault()["LinaValue"].ToString(),
Percentage = g.FirstOrDefault()["LinePercent"].ToString(),
Change = Math.Round(double.Parse(g.FirstOrDefault()["LinaValue"].ToString()) - double.Parse(g.LastOrDefault()["LinaValue"].ToString()), 2)
};
知道为什么它说输入字符串的格式不正确 'select new' 吗?
谢谢
