c# - 收到错误 "No best type found for implicitly-typed array"

Question

这是我为 jqGrid 创建 Json 响应和用于定义单元格成员的 new 关键字的代码，我收到以下消息“找不到隐式类型数组的最佳类型”。

var resRows = results.Select(record => 
            new 
            {
                id = record.Reference,
                cell = **new** []
                {
                    record.Reference,
                    record.TradeDate.ToShortDateString(),
                    record.Currency1,
                    record.Currency2,
                    record.Notional.ToString(),
                    record.EffectiveDate.ToShortDateString(),
                    record.Quote.ToString()                        
                }
            }).ToArray();

我在这里做错了什么？

Answer 1

假设Reference，Currency1 和Currency2 是字符串，只需将其声明为字符串数组即可:

var resRows = results.Select(record => 

    new 
    {
        id = record.Reference,
        cell = new string []
        {
            record.Reference,
            record.TradeDate.ToShortDateString(),
            record.Currency1,
            record.Currency2,
            record.Notional.ToString(),
            record.EffectiveDate.ToShortDateString(),
            record.Quote.ToString()                        
        }
    }).ToArray();
