反序列化字典数组<string,object>

Question

I'm getting a JSON object with an string like:

"rec":[
    {"f":["T","R"],"u":316,"fName":"test","lName":"test2"},
    {"f":["C","R"],"u":990,"fName":"beth","lName":"tin"}
],

I'm trying to de-serialize it using the DataContractSerializer and by having a DataMember contract into a member of type public Dictionary<string,object> [] rec; But i get an error like:

Object of type 'System.Object' cannot be converted to type 'System.Collections.Generic.Dictionary`2[System.String,System.Object]'.

Can someone explain to me how I should go about deserializing this string ?

Answer 1

why not use json.net ?

deserialization from their docu:

string json = @"{""key1"":""value1"",""key2"":""value2""}";

Dictionary<string, string> values = JsonConvert.DeserializeObject<Dictionary<string, string>>(json);

Console.WriteLine(values.Count);
// 2

Console.WriteLine(values["key1"]);
// value1

which could be enhanced on classes with contain certain [Json...] -attributes ... If you are working with DataMember -attributes, you can go straight for json.net, as they support the usage of DataMember and alikes ...

serialization should work too - just have tried lists and alike-stuff yet which worked more than fine for me!

Answer 2

I think you should use the JavaScriptSerializer:

var serializer = new JavaScriptSerializer();
var result = serializer.Deserialize<Dictionary<string, object>>("{" + data + "}")
