Dapper 关于类型转换及返回

这里拿一个接口举例，实现返回企业列表。

IEnumerable<T>解读：https://bbs.csdn.net/topics/392147930

 返回 IEnumerable<T>

[HttpGet]
        public ResponseJson<IEnumerable<Enterprises>> GetEnterPriseByKey(String EnterprisID)
        {
            ResponseJson<IEnumerable<Enterprises>> json = null;
            try
            {
                var EnterModel = conn.Query<Enterprises>("select * from Enterprises where EnterprisID=@EnterprisID",new { EnterprisID = EnterprisID });                
                json = new ResponseJson<IEnumerable<Enterprises>>(ResponseCode.Nomal, EnterModel);
            }
            catch (Exception ex)
            {
                json = new ResponseJson<IEnumerable<Enterprises>>(ResponseCode.Err, ex.Message);
            }
            return json;
        }

返回  List

[HttpGet]
        public ResponseJson<List<Enterprises>> GetEnterpriseList()
        {
            ResponseJson<List<Enterprises>> json = null;
            try
            {                
                List<Enterprises> EnteListVar = conn.Query<Enterprises>("select * from Enterprises").ToList();
                json = new ResponseJson<List<Enterprises>>(ResponseCode.Nomal, EnteListVar);
            }
            catch(Exception ex)
            {
                json = new ResponseJson<List<Enterprises>>(ResponseCode.Err, ex.Message);
            }
            return json;
        }
