            materialSkinManager.Theme = MaterialSkinManager.Themes.LIGHT;

            ManagementObjectCollection moc = mc.GetInstances();
            foreach (ManagementObject mo in moc)
            {
                if (cpuInfo == "")
                {
                    //Get only the first CPU's ID
                    cpuInfo = mo.Properties["processorID"].Value.ToString();
                    break;
                }
                var plainTextBytes = Encoding.UTF8.GetBytes(cpuInfo);
                String hwid = Convert.ToBase64String(plainTextBytes);
                WebClient client = new WebClient();
                Stream stream = client.OpenRead("http://techshow.us/liquid/hwid.txt/");
                StreamReader reader = new StreamReader(stream);
                String content = reader.ReadToEnd();
                if (content.Contains(hwid))
                {

                }
                MessageBox.Show("ok");

            }
        }
    }
}

为什么不显示消息框？香港专业教育学院尝试了大部什么都没有发生ui只是显示和idk做什么\ 请帮助我，我的项目需要这个

Answer 1

if (cpuInfo == "")将始终为true，因为初始化后值不会更改。循环在到达MessageBox代码之前中断。

删除break;以允许代码继续，或

使用continue;代替跳转到循环中的下一个值。

C＃MessageBox无法正常工作
