为什么我不能.ToList()在此添加一个？Intellisense唯一允许的是.ToString()。
//..
string sqlQuery = "SELECT sum(SellingPrice) as SellingPrice, sum(MarkupPercent) as MarkupPercent, sum(MarkupAmount) as MarkupAmount FROM ProfitMargins WHERE QuoteId in @QuoteId group by multiplier";
{
List<ProfitMargin> profitMargin = (List<ProfitMargin>)await conn.QueryAsync<List<ProfitMargin>>(sqlQuery, new { QuoteId = QuoteIds.ToArray()}) //would like to add .ToList() here;
return profitMargin;
}
//..
更新
我相信问题与conn.queryasync（conn是context.Database.Connection.ConnectionString）而不是context.Database.SqlQuery有关
尝试更改为此。
List<ProfitMargin> profitMargin = (await conn.QueryAsync<ProfitMargin>(sqlQuery, new { QuoteId = QuoteIds.ToArray()})).ToList();
要么
var results = await conn.QueryAsync<ProfitMargin>(sqlQuery, new { QuoteId = QuoteIds.ToArray()});
List<ProfitMargin> profitMargin = results.ToList();
我想您是在Task试图打电话时撞到物体.ToList()
