简单的分组和总和将有助于获得结果

public string Name { get; set; }

public string Age { get; set; }

public static IForm<MyForm> BuildForm()
{
    return new FormBuilder<LlegadaBusForm>()
        .Field(nameof(Name)
        .Field(new FieldReflector<MyForm>(nameof(Age))
            .SetType(null)
            .SetDefine(async (state, field) =>
            {
                var data = await GetData(state.Name);
                foreach (var o in data)
                {
                    field
                        .AddDescription(o, o)
                        .AddTerms(o, o);
                }

                return true;
            })
        .Build();
}
