c# - Firebase 值到组合框

Question

我想出了一个代码，但是当表单加载时没有任何反应。如何将 firebase 数据获取到组合框？我走对了吗？

        {
    int i = 0;
    FirebaseResponse resp1 = await client.GetTaskAsync("Counteruser/nodeuser");
    Counter_classuser obj1 = resp1.ResultAs<Counter_classuser>();
    int cntuser = Convert.ToInt32(obj1.cntuser);

    while (true)
    {
        if (i == cntuser)
        {
            break;
        }
        i++;
        try
        {
            FirebaseResponse resp2 = await client.GetTaskAsync("Users/" + i);
            Datausers obj2 = resp2.ResultAs<Datausers>();

            txtusername3.AddItem(obj2.Username);
        }
        catch
        {

        }
    }
}
