What is the best way to retrieve and analyze data from a JSON dataset in C#? Specifically, I need to extract the number of visas issued, the top countries with the most immigrants, and any recent policy changes affecting immigration from the following dataset:
{
  "year": 2021,
  "visas_issued": 4624437,
  "top_immigrant_countries": {
    "Mexico": 1235535,
    "China": 555209,
    "India": 497499,
    "Philippines": 419004,
    "Dominican Republic": 182722
  },
  "policy_changes": [
    {
      "date": "January 2021",
      "description": "Suspension of entry for certain employment-based nonimmigrant visa categories"
    },
    {
      "date": "February 2021",
      "description": "Repeal of the Muslim Ban"
    },
    {
      "date": "March 2021",
      "description": "Creation of a task force to reunite families separated at the border"
    }
  ]
}
Can you provide a C# code snippet that utilizes JSON data to extract the required information?

To retrieve and analyze data from a JSON dataset in C#, you can use the Newtonsoft.Json library. First, you would need to install the library using NuGet package manager (if you haven't already):

```
Install-Package Newtonsoft.Json
```

Here's a C# code snippet that demonstrates how to deserialize and extract the required information from your JSON dataset:

```csharp
using System;
using System.Collections.Generic;
using Newtonsoft.Json;

public class ImmigrationData
{
    public int Year { get; set; }
    public int Visas_issued { get; set; }
    public Dictionary<string, int> Top_immigrant_countries { get; set; }
    public List<PolicyChange> Policy_changes { get; set; }
}

public class PolicyChange
{
    public string Date { get; set; }
    public string Description { get; set; }
}

class Program
{
    static void Main(string[] args)
    {
        string json = @"{
                          ""year"": 2021,
                          ""visas_issued"": 4624437,
                          ""top_immigrant_countries"": {
                            ""Mexico"": 1235535,
                            ""China"": 555209,
                            ""India"": 497499,
                            ""Philippines"": 419004,
                            ""Dominican Republic"": 182722
                          },
                          ""policy_changes"": [
                            {
                              ""date"": ""January 2021"",
                              ""description"": ""Suspension of entry for certain employment-based nonimmigrant visa categories""
                            },
                            {
                              ""date"": ""February 2021"",
                              ""description"": ""Repeal of the Muslim Ban""
                            },
                            {
                              ""date"": ""March 2021"",
                              ""description"": ""Creation of a task force to reunite families separated at the border""
                            }
                          ]
                        }";

        ImmigrationData data = JsonConvert.DeserializeObject<ImmigrationData>(json);

        Console.WriteLine($"Visas issued: {data.Visas_issued}");
        Console.WriteLine("Top Immigrant Countries:");
        
        foreach (var country in data.Top_immigrant_countries)
        {
            Console.WriteLine($"- {country.Key}: {country.Value}");
        }
        
        Console.WriteLine("Policy changes:");
        foreach (var policyChange in data.Policy_changes)
        {
            Console.WriteLine($"- {policyChange.Date}: {policyChange.Description}");
        }
    }
}
```

This code snippet defines a C# class `ImmigrationData` with properties that correspond to your JSON dataset structure. It then deserializes the JSON dataset using Newtonsoft.Json library's `JsonConvert.DeserializeObject()` method, extracts the required information, and prints it to the console.

            int visasIssued = data.VisasIssued;
            Console.WriteLine($"Number of visas issued: {visasIssued}");

            // Extract top immigrant countries and their counts
            var topCountries = new Dictionary<string, int>();

            }

            // Extract recent policy changes
            Console.WriteLine("Recent policy changes:");
            foreach (var change in data.PolicyChanges)
            {
                Console.WriteLine($"{change.Date}: {change.Description}");
            }

        }
    }
}
```

In this code, we first load the JSON data from a file using `File.ReadAllText()`. Then, we deserialize the JSON data into a `ImmigrationData` object using `JsonSerializer.Deserialize<>()`.

Next, we extract the required information from the `ImmigrationData` object:

- `visasIssued`: We retrieve the value of the `VisasIssued` property.
- `topCountries`: We iterate over the `TopImmigrantCountries` dictionary and add each country-count pair to a new `Dictionary<string, int>` object.
- `policyChanges`: We iterate over the `PolicyChanges` list and print each policy change.

Finally, we print the extracted information to the console.

Note that this code assumes that the JSON data is formatted as shown in the example provided. If the format of the JSON data differs, you may need to modify the `ImmigrationData` class and the code that extracts the data accordingly.
