Cson请求太大而无法反序列化C＃ [英] The json request was too large to be deserialized C#

问题描述

我想在不使用它的情况下反序列化大型json文件：

I wanted to deserialized large json file without using this :

<appSettings>
  <add key="aspnet:MaxJsonDeserializerMembers" value="150000" />
</appSettings>

因为它会影响整个项目ct ..



我只是想为了安全而采取行动..



我尝试过：



这是我的代码：

at the web.config because it will affect the entire project..

I just wanted to put it per action to be safe..

What I have tried:

Here is my code:

public IEnumerable<PricingVehicleEquipmentsOptionModelDto> GetFactoryOptions(long vehicleId)
        {
            var optionalequips = new List<PricingVehicleEquipmentsOptionModelDto>();
            var optionEquipmentJson = _dbContext.IVehicleOptions.FirstOrDefault(o => o.Name == "Optional_Equipment" & o.IVehicleId == vehicleId);
            var vehicle = _dbContext.IVehicles.FirstOrDefault(o => o.Id == vehicleId);

            var optionEquipments = optionEquipmentJson != null ? JsonConvert.DeserializeObject<List<PricingVehicleEquipmentsOptionModelDto>>(optionEquipmentJson.OptionCodes) : null;

            var style = optionEquipments.Select(o => new PricingVehicleEquipmentsOptionModelDto
            {
                TypeId = o.TypeId,
                TypeName = o.TypeName,
                Description = o.Description,
                oemCode = o.oemCode != null ? o.oemCode : o.chromeCode,
                IsApplied = o.IsApplied,
                StyleIds = o.StyleIds
            });

            foreach(var s in style)
            {                
                var optionStyle = s.StyleIds.Any(d => d.ToString() == vehicle.S_StyleId);

                if(optionStyle)
                {
                    optionalequips.Add(s);
                }
            };
       
            return optionalequips;
        }
