总结Linq或者lamdba的写法

 1                var head = new OmsEcorderHead
 2                 {
 3                     PkEcorderHead = OrderHeadId,
 4                     AppId = appid,
 5                     Integral = Convert.ToDecimal(reqdata.Body.Integral.ToString()),
 6                     ShipIntegral = Convert.ToDecimal(reqdata.Body.ShipIntegral.ToString()),
 7                     //必填
 8                     Co = reqdata.Body.CO,
 9                     Whse = reqdata.Body.WHSE,
10                     ReceiptTime = Convert.ToDateTime(reqdata.Body.ReceiptTime.ToString("yyyy-MM-dd HH:mm:ss"))
11                 }

                var InvoiceTitle = new string[] { "a", "b", "c", "d ", "e" };
                if (InvoiceTitle.Where<string>(l => l == reqdata.Body.InvoiceTitle.ToLower()).Count() == 0)
                     throw new ECOrderException { ErrorCode = "X1007-01", TransMessage = "传入的InvoiceTitle的值不正确，请修改" };

 将传递过来的一个实体，赋值给一个自己的类， 
 1 var ary = reqdata.Body.Detail.Select(l => new OMSECData.orderDetail
 2                 { 
 4                     GoodsName = l.GoodsName,
 5                     GoodsNumber = l.GoodsNumber,
 6                     GoodsPrice = l.GoodsPrice,
 7                     TradeIntegral = l.TradeIntegral,
 8                     ShopMoney = l.ShopMoney,
 9                     GoodsAmount = l.GoodsAmount，   
16                     CreateDateTime = Convert.ToDateTime(DateTime.UtcNow.AddHours(8))
17                 }).ToList();

                   foreach (var item in ary)
                    head.OmsEcorderDetail.Add(item);

 1 ActionResult result = null;
 2 
 3  var obj = new JObject
 4                 {
 5                     {"Head", new JObject
 6                         {
 7                             { "TransMessage","" },
 8                             { "TransCode",transCode },
 9                             { "TransId", reqdata.Head.TransId },
10                             { "ErrorCode", "" }
11                         }
12                     },
13                     {"Body", new JObject
14                         {
15                             { "CreateDateTime", DateTimeOffset.Now.AddHours(8).ToUnixTimeSeconds().ToString() }
16                         }
17                     }
18                 };
19 
20                 result = new ContentResult()
21                 {
22                     Content = Newtonsoft.Json.JsonConvert.SerializeObject(obj),
23                     ContentType = "application/json"
24                 };
