WCF 数据数据 DataTable

一般在WCf数据大数据是 List集合 或者 Json。

     public DataTable GetProperitybyModelCode(string modelCode)
        {
            using (var entity = new USERRIGHTEntities())
            {
  //查询对应的表名和表的ID
                var queryResult = (from fx in entity.T_ModelInfo
                                   join tp in entity.T_ModelProperties on fx.F_ModelCode equals tp.F_ModelCode
                                   where fx.F_ModelCode == modelCode
                                   select new { TableName = tp.F_ProperieTable, ProperityCode = tp.F_ProperieCode }).FirstOrDefault();

                 if (queryResult != null && queryResult.TableName != null)
                {
                    var retVal = new DataTable();
                    var entityConn = (EntityConnection)entity.Connection;
                    var sqlConn = (SqlConnection)entityConn.StoreConnection;
                    var cmdReport = new SqlCommand(string.Format("select * from [{0}] where F_ProperieCode={1}", queryResult.TableName, queryResult.ProperityCode), sqlConn);
                    var daReport = new SqlDataAdapter(cmdReport);
                    using (cmdReport)
                    {
                        daReport.Fill(retVal);
                    }
                    retVal.TableName = queryResult.TableName;//这里一定要写个表名  不然在返回客户端的时候 会报个错。
                    return retVal;

                }
            }
            return null;
        }

客户端调用：

  var client=new BpjdqOperatorServiceClient(SIMUBUSINESSLOGICDATA.WebServiceApp.WsHttpBinding(),SIMUBUSINESSLOGICDATA.WebServiceApp.BpjdqEndpoingAddress());
            client.BeginGetProperitybyModelCode("0001", delegate(IAsyncResult asyncResult)
                {
                    var query = client.EndGetProperitybyModelCode(asyncResult);
                    if (query.Rows.Count>0)
                    {
                        foreach (var item in query.Rows)
                        {
                            
                        }
                    }
             
                }, null);
