How Can I Deserialize a JSON Object with Numeric IDs as Keys into a Strongly Typed C# Object?

converted the JSON object with ID as the name to a strong type C# object

When the JSON object with a digital ID key is serialized into a strong type C# object, it will encounter challenges. Consider the following JSON response:

In order to create a strong type object, you have defined the classes of "Pollsandsurveysstatistics", "Atmencestatistics" and "SessionPerformancestats". However, the problem is the top structure of your C# object "WebinarperFormancestats".
<code>{
    "5234592":{
    "pollsAndSurveys":{
        ...
    },
    "attendance":{
        ...
    }
    },
    "5235291":{
    "pollsAndSurveys":{
        ...
    },
    "attendance":{
        ...
    }
    }
}</code>

In order to solve this problem, please convert the root object in C# to a dictionary:

This method allows JSON.NET to sequence the JSON object into a dictionary, where the ID number is used as the key. In order to ensure the correct type of treatment, you can refine the statement as follows:
<code class="language-csharp">var dictionary = JsonConvert.DeserializeObject<Dictionary<long, SessionPerformanceStats>>(theJsonResponse);</code>

This modification ensures that the ID key is explained as a long integer. By using the dictionary as the root object, you can use the ID key to access session performance statistics.
<code class="language-csharp">var dictionary = JsonConvert.DeserializeObject<Dictionary<long, SessionPerformanceStats>>(theJsonResponse);</code>
