Convert object to array in c#

using System;
using System.Collections.Generic;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;

class Program
{
    public class Person
    {
        public string Name { get; set; }
        public string Dob { get; set; }
    }

    static void Main(string[] args)
    {
        string jsonString = @"[
            { ""Name"": ""siva"", ""Dob"": ""05-09-2000"" }
        ]";

        List personList = JsonConvert.DeserializeObject>(jsonString);

        Console.WriteLine("Converted List of Persons:");
        foreach (Person person in personList)
        {
            Console.WriteLine($"Name: {person.Name}, Dob: {person.Dob}");
        }

        Console.WriteLine($"Number of Persons: {personList.Count}");
    }
}

Please use the code below which will calculate the count aswell as it will convert obj into array

public async Task> ConvertObjToArray(object obj)
{
    if (obj is IEnumerable stringArray)
    {
        List result = stringArray.ToList();
        int count = result.Count;
        return result;
    }
    else
    {
        // Handle the case where the object cannot be converted to an array of strings.
        // You might throw an exception or return an empty list based on your requirements.
        return new List();
    }
}

using System;
using System.Collections.Generic;

public async List ConvertObjToArray(object obj)
{
    if (obj is IEnumerable stringArray)
    {
        List convertedArray = new List(stringArray);
        int count = convertedArray.Count;
        return convertedArray;
    }
    else
    {
        // Handle the case where the object is not an array of strings.
        // You can throw an exception or return an empty list, depending on your use case.
        return new List();
    }
}

Hi imran,

Request object as like below

[{

"Name": " siva",

"Dob":" 05-09-2000"

}]

How can I get the count of array from above object

To achieve this, first determine the type of the object and then convert it accordingly. Since the method signature you provided is for a list of strings, Here's how you can do it:

public async Task ConvertObjToArray(object obj)
{
    if (obj is null)
    {
        return new string[0]; // Return an empty array if the object is null
    }
	if (obj is string str) // Check if the object is already a string
    {
        return new string[] { str }; // Convert the string to a string array with one element
    }
    if (obj is IEnumerable stringList) // Check if the object is a collection of strings
    {
        return stringList.ToArray(); // Convert the collection to a string array
    }
}
