通过SqlParameter传时间参数,代码如下:
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();
结果一直报错
不存在从对象类型 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机类型的映射。
英文报错
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.
通过搜索
看到后面的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();
结果好了,真神奇!
搞定!
