CRM Entity 之Money转string int类型等

 Money转string

左右都是string

 //服务站地址

vehicleDetail["yt_servicestation_address"]=serviceStationCollEntity.Contains("yt_street")? serviceStationCollEntity["yt_street"] : null;

右侧Money 左侧string，需要转换成string

//工时单价       

vehicleDetail["yt_workinghours"]=serviceStationCollEntity.Contains("yt_unit_price")? serviceStationCollEntity.GetAttributeValue<Money>("yt_unit_price").Value.ToString() : null;
