如何在反序列化时字段为空时将默认值设置为Guid

Question

I am trying to pull records from server via webservice in and in my model I have a parameter named public String mId {get;set;} and my JSON structure is as follows

{  "name":"Jhon",  "mId":"",  "address":"55 jump street" }

Now when mId is blank i want to generate a new GUID for this field while deserializing json using Newton JSON as [DefaultValue("")] is accepting only constant value i can not use Guid.NewGuid() over there

Answer 1

That is not what DefaultValue is used for. To add a default value:

string mId { get; set; } = Guid.NewGuid()
