处理反序列化错误

Question

I have class to deserialize from json

class SeeSharp
{
   public int Number;  
}

Good json is smth like

{Number:1}

Wrong json which comes from PHP is

{Number:false}

I use following way to handle deserialization error http://blog.mrlacey.co.uk/2012/03/debugging-deserialization-errors-in.html

When fails reading member of type string/int/double/bool/etc, I would like to set it's value to default of this type and mark that error as handled.

Currently, JsonSerializationSettings.Error delegate doesn't allow to set value to failed member and doesn't show any information about type of member failed.

If there is an option to do that in another way, would be great to know it.

Answer 1

Can you use this class?

public class SeeSharp
{
    public string Number
    {
        get
        {
            return _number.ToString();
        }

        set
        {
            if (!int.TryParse(value, out _number))
                _number = default(int);
        }
    }

    public int _Number { get; set; }
}

JsonConvert will use the string property Number to set data, which handles the parsing itself. And then use the property _Number in your code as int
