Loading JSON from URL with multiple items

[tryingtolearn]

I'm very close to a solution and I think the problem is due to one line of code, but I can't figure out what I am doing wrong. I am using JSON.Net to load a JSON file from a specific URL. The JSON file has about 100 items. I've seen examples of deserialization with one item but not multiple. I need the JSON items to be deserialized into a list of objects. I've achieved the below by using examples I've found online. First, here is the JSON structure:

[
    {"Username":"some_username1","password":"some_password1"}
    {"Username":"some_username2","password":"some_password2"}
    {"Username":"some_username3","password":"some_password3"}
]

I have this class:

[COLOR=green]// To parse this JSON data, add NuGet 'Newtonsoft.Json' then do:[/COLOR]
[COLOR=green]//[/COLOR]
[COLOR=green]//    using ProgramUser;[/COLOR]
[COLOR=green]//[/COLOR]
[COLOR=green]//    var person = Person.FromJson(jsonString);[/COLOR]

    [COLOR=blue]using[/COLOR] System;

        [COLOR=blue]public[/COLOR] [COLOR=blue]string[/COLOR] username { [COLOR=blue]get[/COLOR]; [COLOR=blue]set[/COLOR]; }
 
        [[COLOR=#2b91af]JsonProperty[/COLOR]([COLOR=#a31515]"password"[/COLOR])]
        [COLOR=blue]public[/COLOR] [COLOR=blue]string[/COLOR] password { [COLOR=blue]get[/COLOR]; [COLOR=blue]set[/COLOR]; }
 
 
    }

    [COLOR=blue]public[/COLOR] [COLOR=blue]partial[/COLOR] [COLOR=blue]class[/COLOR] [COLOR=#2b91af]Person[/COLOR]
    {
        [COLOR=blue]public[/COLOR] [COLOR=blue]static[/COLOR] [COLOR=#2b91af]Person[/COLOR][] FromJson([COLOR=blue]string[/COLOR] json) => [COLOR=#2b91af]JsonConvert[/COLOR].DeserializeObject<[COLOR=#2b91af]Person[/COLOR][]>(json, GISv1.[COLOR=#2b91af]Converter[/COLOR].Settings);
    }

    [COLOR=blue]public[/COLOR] [COLOR=blue]static[/COLOR] [COLOR=blue]class[/COLOR] [COLOR=#2b91af]Serialize[/COLOR]
    {
        [COLOR=blue]public[/COLOR] [COLOR=blue]static[/COLOR] [COLOR=blue]string[/COLOR] ToJson([COLOR=blue]this[/COLOR] [COLOR=#2b91af]Person[/COLOR][] self) => [COLOR=#2b91af]JsonConvert[/COLOR].SerializeObject(self, GISv1.[COLOR=#2b91af]Converter[/COLOR].Settings);
    }

    [COLOR=blue]internal[/COLOR] [COLOR=blue]static[/COLOR] [COLOR=blue]class[/COLOR] [COLOR=#2b91af]Converter[/COLOR]
    {
        [COLOR=blue]public[/COLOR] [COLOR=blue]static[/COLOR] [COLOR=blue]readonly[/COLOR] [COLOR=#2b91af]JsonSerializerSettings[/COLOR] Settings = [COLOR=blue]new[/COLOR] [COLOR=#2b91af]JsonSerializerSettings[/COLOR]
        {
            MetadataPropertyHandling = [COLOR=#2b91af]MetadataPropertyHandling[/COLOR].Ignore,
            DateParseHandling = [COLOR=#2b91af]DateParseHandling[/COLOR].None,
            Converters = {
                [COLOR=blue]new[/COLOR] [COLOR=#2b91af]IsoDateTimeConverter[/COLOR] { DateTimeStyles = [COLOR=#2b91af]DateTimeStyles[/COLOR].AssumeUniversal }
            },
        };
    }
}

When I try to create an instance of the above class, I am getting errors.

                        [COLOR=blue]while[/COLOR] ((line = reader.ReadLine()) != [COLOR=blue]null[/COLOR])
                        {

                          lstPeople.Add(personToAdd);
                        }
                    }
                }
                [COLOR=blue]catch[/COLOR] ([COLOR=#2b91af]Exception[/COLOR]) { }
                [COLOR=green]// if string with JSON data is not empty, deserialize it to class and return its instance [/COLOR]
                [COLOR=blue]return[/COLOR] ![COLOR=blue]string[/COLOR].IsNullOrEmpty(json_data) ? [COLOR=#2b91af]JsonConvert[/COLOR].DeserializeObject<[COLOR=#2b91af]T[/COLOR]>(json_data) : [COLOR=blue]new[/COLOR] [COLOR=#2b91af]T[/COLOR]();
            }
        }
 
    }
}

I am getting an error at " People.Add(personToAdd)" It will not let me create an instance of this. It says "Cannot convert ProgramUser.Person[] to ProgramUser.Person"

I'm at a loss here. Any suggestions are greatly appreciated.

Thank you,
Rob
