通過SqlParameter傳時間參數，代碼如下：

                    var param = new List<SqlParameter>();
                    param.Add(new SqlParameter("@StartTime", DateTime.Parse(req.StartTime)));
                    param.Add(new SqlParameter("@EndTime", DateTime.Parse(req.EndTime)));
                    
                    response.List = _ctx.Database.SqlQuery
 
<ReceiveSummeryItem>(sql, param.ToList()).ToList();

結果一直報錯

不存在從對象類型 System.Collections.Generic.List`1[[System.Data.SqlClient.SqlParameter, System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]] 到已知的托管提供程序本機類型的映射。

英文報錯

No mapping exists from object type System.Collections.Generic.List`1[[System.Data.SqlClient.SqlParameter, System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]] to a known managed provider native type.

通過搜索

看到後面的ToList() 改成 ToArray()

                    var param = new List<SqlParameter>();
                    param.Add(new SqlParameter("@StartTime", DateTime.Parse(req.StartTime)));
                    param.Add(new SqlParameter("@EndTime", DateTime.Parse(req.EndTime)));
                    
                    response.List = _ctx.Database.SqlQuery
 
<ReceiveSummeryItem>(sql, param.ToArray()).ToList();
                    response.TotalCount = response.List.Count();

結果好了，真神奇！

搞定！
