Mapping Json Keys to Class Properties

[selo-dev]

Hello, I'm trying to use fastJSON for a document that has a "-" character in its key name: { „my-key“: „…“ }

Character "-" is not allowed in property names in c#. How can I deserialize to the next structure with renaming to the property "MyKey"

Class Root { Public string MyKey { get; set;} }

Thanks for the answer.

You can use DataMember attributes:

Class Root
{
    [DataMember(Name = "my-key")]
    public string MyKey { get; set;}
}

I forgot to say that I am using fastJSON 3.5 and the classes from "System.Runtime.Serialization.dll" are not available for me

Currently you can't on v3.5, try upgrading your EXE and fastJSON to v4.0 (all else should work with v3.5 DLLs)

I cannot use the new runtime because this is used in "sql clr" in Sql Server 2008 r2. However, I use the following construct for this and it works for me: String jsonText = fastJSON.JSON.ToJSON(myRootInstance).Replace("\"MyKey\"", "\"my-key\"");

Maybe you can add another mapping method in the next versions

Try v2.3.3 I've added fastJSON.DataMember and let me know

Great! It works!
