Your data structure and your JSON do not match.
Your JSON is this:
{
"JsonValues":{
"id": "MyID",
...
}
}
But the data structure you try to serialize it to is this:
class ValueSet
{
[JsonProperty("id")]
public string id
{
get;
set;
}
...
}
You are skipping a step: Your JSON is a class that has one property named JsonValues, which has an object of your ValueSet data structure as value.
Also inside your class your JSON is this:
"values": { ... }
Your data structure is this:
[JsonProperty("values")]
public List<Value> values
{
get;
set;
}
Note that { .. } in JSON defines an object, where as [ .. ] defines an array. So according to your JSON you don't have a bunch of values, but you have one values object with the properties value1 and value2 of type Value.
Since the deserializer expects an array but gets an object instead, it does the least non-destructive (Exception) thing it could do: skip the value. Your property values remains with it's default value: null.
If you can: Adjust your JSON. The following would match your data structure and is most likely what you actually want:
{
"id": "MyID",
"values": [
{
"id": "100",
"diaplayName": "MyValue1"
}, {
"id": "200",
"diaplayName": "MyValue2"
}
]
}
