How to convert Json String to Object with Dictionary using JayRock

[张涛 黄]

Hello everyone, I'm new to jayrock, also C# :)
I want to convert a Json string to an Object in C#. the string is like
this:
{"dealName":"name1","properties":{"a":"1", "b":"2"}}

The class defined like this:
public class DealInfo
{
public string dealName;
public Dictionary<string, string> properties;
}

And I use this code to convert:
DealInfo dl = JsonConvert.Import(typeof(DealInfo), jsonString) as
DealInfo;

I found it just converted the dealName field, but the properties field
count is 0.
So, what's the problem? How to fix it?
Many thanks!

Try with Dictionary changed to IDictionary, like this:

 

public class DealInfo {
  public string dealName;

  public IDictionary<string, string> properties;
}

It still doesn't work.
when using import method, it throws JsonException "don't known how to
import System.Collections.Generic.IDictionary'2..."
I'm using the .net 1.1 releaed package.

The full exception message is:

Don't know how to import System.Collections.Generic.IDictionary'2
[[System.String, mscorlib, Version=2.0.0.0, Culture=neutral,

If you're using generic types, why aren't you using the binaries for .NET 2.0?

we are using a very old system developed centuries ago, and developing a plugin-in for it, and we can't change the run-time environment.

Can the work be done with the Jayrock? 

And now I'm thinking of manual conversion form JsonObject to my object.

If the runtime environment is 1.1 then I'm surprised you were able to load your own assembly at all considering it uses generics like Dictionary<string, string>. Another option you have is to simple type your properties property as non-generic IDictionary from System.Collections namespace.

Thank you very much.
I studied generic & non-generic type in .Net Framework, and finally
solved the problem, thank you again!
