I'm using the JSON API .Net Core to create .Net API. How to add total-count in meta-data? enter image description here

public class BaseEntity : Identifiable, IHasMeta
    {

        public string CreatedBy { get; set; }

        public string ModifiedBy { get; set; }

        public Dictionary<string, object> GetMeta(IJsonApiContext context)
        {
            return new Dictionary<string, object> {
            { "copyright", "Copyright Croos" },
            { "authors", new string[] { "Croos" } }
        };
        }
    }

There is nothing about it in the document. Thanks.

Firstly, enable the IncludeTotalRecordCount options:

public void ConfigureServices(IServiceCollection services)
{
    ... other services

    services.AddJsonApi<AppDbContext>(o =>{
        o.IncludeTotalRecordCount = true;
    });
}

And now we can retrieve the total records by context.PageManager.TotalRecords :

public class Person : Identifiable, IHasMeta
{
    [Attr("name")]
    public string Name { get; set; }

    public Dictionary<string, object> GetMeta(IJsonApiContext context)
    {
        return new Dictionary<string, object> {
            { "total-records", context.PageManager.TotalRecords },
        };
    }
}
