Convert JSON string to C# dictionary

Question

I have a JSON string

{
  "Date":"21/11/2010"
  "name": "TEST"
  "place":"xyz"
}

I want to convert it into a C# dictionary without using a third party library

Do not downvote because you dislike the choice to use no 3rd Party libs. Maybe there is a good reason for. So clarify before judging — zewa666

No there's not. You do not have to reinvent the wheel everytime. But if he wants to, then he should show us his effort and the exact problem. — jAC

Sometimes understanding what a framework does is quite helpful instead blindly using it. So learning would be a reason not to choose a whole API for just one small feature. — zewa666

You can do it natively since net 3.5 with jsonserializer.

var jss = new JavaScriptSerializer();
var dict = jss.Deserialize<Dictionary<string,string>>(jsonText);
var place = dict["place"]; // "xyz"

Here is a simple tutorial for your case: Quick JSON Serialization/Deserialization in C#

Requires the System.Web.Extensions reference. If you can't find it, your program is probably using a Client target framework. Use a "Full" target framework.

@zewa666 Thanks man!! I spent 4 hours behind this and found extremely good solution. This solution follows KISS principal.

Same problem as @ekkis, doesn't work for me as shown, however, using <string, dynamic> or just dynamic as show when you follow the tutorial link does.

You can now (for a while) use the inbuilt System.Text.Json for this as follows:

var dict = JsonSerializer.Deserialize<Dictionary<string, string>>(jsonString);
