I am using ASP Net Core 2.2
I seralize this dynamic object
var stuff1 = new
{
Name = "John",
Surname = "Smith",
Addresses = new[] {
new { City = "New York", State = "NY"},
new { City = "Milano", State = "IT" }
};
var stuff1Serialized = JsonConvert.SerializeObject(stuff1)
This is the serialized object:
{"Name":"John","Surname":"Smith"}
Now, I get this string and I deserialized it
dynamic stuff1Deserialized = JsonConvert.DeserializeObject(stuff1Serialized);
I expect that sutff1 and stuff1Deseralized has the same strucure, but they are different, why?
In Immediate window:
stuff1.name
"Jhon"
stuff1Deserialized.Name
{John}
First: '((Newtonsoft.Json.Linq.JToken)stuff1Deserialized.Name).First' threw an exception of type 'System.InvalidOperationException'
HasValues: false
Last: '((Newtonsoft.Json.Linq.JToken)stuff1Deserialized.Name).Last' threw an exception of type 'System.InvalidOperationException'
Next: null
Parent: {"Name": "John"}
Path: "Name"
Previous: null
Root: {{
"Name": "John",
"Surname": "Smith"
}}
Type: String
Value: "John"
Results View: Expanding the Results View will enumerate the IEnumerable
I use the object with this simple DotLiquid template:
Hello {{Name}} {{Surname}}. Number of Addresses: {{Addresses.size}} - {{Addresses[0].City}} - {{Addresses[1].City}}
With stuff1 object I got the exptected result:
Hello John Smith. Number of Addresses: 2 - New York - Milano
With stuff1Deserialized object I got this result:
Hello John Smith. Number of Addresses: 2 - -
Update as per comment
I find one way to do this:
1 - object dynamic sample:
dynamic dynamicStuff = new
{
Name = "John",
Surname = "Smith",
Obj = new { City = "New York", State = "NY" },// i add this to test object
Addresses = new[]
{
new { City = "New York", State = "NY"},
new { City = "Milano", State = "IT" }
}
};
2 - serializing and deserializing to build dynamic object:
dynamic dynamicStuffDeSerialized = JsonConvert.DeserializeObject(JsonConvert.SerializeObject(dynamicStuff));
3 - Converting dynamic
object to JObject
and building Dictionary
Of (string, object) by converting JObject
to Dictionary
:
Dictionary<string, object> keyValuePairs = ConvertJObject(JObject.FromObject(dynamicStuffDeSerialized));
private static Dictionary<string, object> ConvertJObject(JObject jObject)
{
Dictionary<string, object> keyValuePairs = new Dictionary<string, object>();
foreach (var property in jObject)
{
if (property.Value.Type == JTokenType.Array)
keyValuePairs.Add(property.Key, ConvertJArray(property.Value.Select(o=>(JObject)o)));
else if (property.Value.Type == JTokenType.Object)
keyValuePairs.Add(property.Key, ConvertJObject((JObject)property.Value));
else
keyValuePairs.Add(property.Key, property.Value.ToString());
}
return keyValuePairs;
}
private static List<Dictionary<string, object>> ConvertJArray(IEnumerable<JObject> jObjects)
{
return jObjects.Select(o => ConvertJObject(o)).ToList();
}
Note That, you can use ToObject
to convert JObject
To Dictionary
, but it's convert just the simple value not object or array, like:
JObject jObject = JObject.FromObject(dynamicStuffDeSerialized);
Dictionary<string, object> dict = jObject.ToObject<Dictionary<string, object>>();
4 - use Hash.FromDictionary
not Hash.FromAnonymousObject
:
Template templatedynamicStuff = Template.Parse("Hello {{Name}} {{Surname}} City in Object {{Obj.City}}. Number of Addresses: {{Addresses.size}} - {{Addresses[0].City}} - {{Addresses[1].City}}");
string result = templatedynamicStuff.Render(Hash.FromDictionary(keyValuePairs));
Note that, i changed the template
by adding City in Object {{Obj.City}}
5 - TEST
Console.WriteLine(result);
6 - OUTCOMES :
Hello John Smith City in Object New York. Number of Addresses: 2 - New York - Milano
Old answers
According to newtonsoft documentation, You can use DeserializeAnonymousType instead of DeserializeObject
for deserializing Anonymous Object. but DeserializeAnonymousType
needs a definition
of Anonymous Type To get the same object .
Like the following code :
var stuff1 = new
{
Name = "John",
Surname = "Smith"
};
var stuff1Serialized = JsonConvert.SerializeObject(stuff1);
var definition = new { Name = "", Surname = "" };
dynamic stuff1Deserialized = JsonConvert.DeserializeAnonymousType(stuff1Serialized, definition);
Update as per comment
You can use JObject
or ExpandoObject
to get properties names and values , like the following code:
dynamic stuff1 = new
{
Name = "John",
Surname = "Smith"
};
var stuff1Serialized = JsonConvert.SerializeObject(stuff1);
dynamic stuff1DeSerialized1 = JsonConvert.DeserializeObject(stuff1Serialized);
foreach (JProperty property in JObject.FromObject(stuff1DeSerialized1))
{
Console.WriteLine($"Key:{property.Name}, Value:{property.Value}");
}
ExpandoObject stuff1DeSerialized2 = JsonConvert.DeserializeObject<ExpandoObject>(stuff1Serialized, new ExpandoObjectConverter());
foreach(KeyValuePair<string, object> keyValue in stuff1DeSerialized2.ToList())
{
Console.WriteLine($"Key:{keyValue.Key}, Value:{keyValue.Value}");
}
I hope to find other solution and share it with you.
