Simple Json C# Correct Way to Deserialize Dictionary

We are using the RESTSharp Library to work with third-party REST-based APIs, which by default support XML and JSON deserialization. However, their documentation for Deserialization covers a limited, simple example, which was not sufficient to help us consume Complex JSON output.

We are using http://json2csharp.com/ to convert JSON string to C# class. Which works perfectly when a JSON string is in a simple structure. but when it comes to Deserialize to JSON to Dictionary< string, class> the class generated using json2csharp.com fails.

Example:

Consider following complex JSON response which requires Dictionary<string, class>.

JSON:

"response": {
	"1007": {
		"total": {
			"inStock": 10,
			"onHand": 9,
			"allocated": 1
		}
	},
	"1008": {
		"total": {
			"inStock": 0,
			"onHand": 0,
			"allocated": 0
		}
	}
}

Output after converting JSON to C# class using converter tool(https://json2csharp.com/):

public class Total
{
    public int InStock { get; set; }
    public int OnHand { get; set; }
    public int Allocated { get; set; }
}

public class StockDetails1007
{
    public Total Total { get; set; }
}

public class StockDetails1008
{
    public Total Total { get; set; }
}

public class Response
{
    public StockDetails1007 Stock1007 { get; set; }
    public StockDetails1008 Stock1008 { get; set; }
}

public class RootObject
{
    public Response Response { get; set; }
}

Wrong way to put Dictionary:

public class Response
{
    public Dictionary<string, Product> Products { get; set; }
}

public class RootObject
{
    public Response Response { get; set; }
}

The right way to put Dictionary:

public class RootObject
{
    // Corrected the Dictionary syntax by using proper < and > characters
    public Dictionary<string, Product> Response { get; set; }
}

public class Product
{
    public Total Total { get; set; }
}

public class Total
{
    public int InStock { get; set; }
    public int OnHand { get; set; }
    public int Allocated { get; set; }
}
