Encountering a compilation error while trying to utilize Newtonsoft.Json in my Blazor application

This snippet contains the following code:

@page "/"
@using Newtonsoft.Json
@using System.Text.Json
@using System.Text.Json.Serialization

<h1>Hello World</h1>

@code {

public class Account
{
    public string Email { get; set; }
    public bool Active { get; set; }
    public DateTime CreatedDate { get; set; }
    public IList<string> Roles { get; set; }
}

Account account = new Account
{
    Email = "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="6e040f030b1d2e0b072428c"><i class="__cf_email__" style="display:none;">[email protected]</i></a>",
    Active = true,
    CreatedDate = new DateTime(2013, 1, 20, 0, 0, 0, DateTimeKind.Utc),
    Roles = new List<string>
    {
        "User",
        "Admin"
    }
};

string json = JsonConvert.SerializeObject(account, Formatting.Indented);

}

Encountered error:

error CS0236: A field initializer cannot reference the non-static field, method, or property 'Index.account'

I am currently in the process of learning Blazor and anticipate a successful build for this project.

Answer №1

In order to improve your code organization, it is recommended to create a constructor or another method and encapsulate your code within it.

@code {

    public class Customer
    {
        public string Name { get; set; }
        public int Age { get; set; }
        public DateTime RegistrationDate { get; set; }
        public IList<string> Interests { get; set; }
    }

    public Details()
    {
        Customer customer = new Customer
        {
            Name = "John Doe",
            Age = 30,
            RegistrationDate = new DateTime(2020, 5, 15, 0, 0, 0, DateTimeKind.Utc),
            Interests = new List<string>
            {
                "Sports",
                "Music"
            }
        };

        string jsonDetails = JsonConvert.SerializeObject(customer, Formatting.Indented);
        
        Console.WriteLine(jsonDetails); // Output the serialized JSON for the customer details
    }

}

Answer №2

IList cannot be serialized. Replace it with List<T>.
