Deserialize json base64 binary in .net using DataContractJsonSerializer

Question

Hi, I have a problem deserializing base64 json back to a .net object using wcf datacontract ....

I have this for deserialization:

public static T FromJSON<T>( this string json )
{
    using ( MemoryStream ms = new MemoryStream(ASCIIEncoding.Default.GetBytes(json)) )
    {
        DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));

        return (T)ser.ReadObject(ms);
    }
}

and ... I have it in my model class ...

[DataMember]
[Column(AutoSync = AutoSync.Always, DbType = "rowversion not null", CanBeNull = false, IsDbGenerated = true, IsVersion = true, UpdateCheck = UpdateCheck.Never)]
public byte[] timestamp { get; set; }

and ... I pass json back like that ...

[{"id":"1","type":"H","date_issued":"\/Date(1286856000000)\/","date_ceu":"\/Date(1603166400000)\/","current":true,"timestamp":"AAAAAAAAD7M="}]

and for some reason he just refuses to just translate that base64 back to byte [] ... there must be some other way to make it work ...

also, fyi I use ASP.NET MVC and Html.Hidden (...), which serializes the binary in base64 to start with ...

thank!
