如何保存控制数组

Question

我有这段代码，允许用户创建一个按钮数组，任何一个都在 from 中。 此处和这里是我正在做的两个示例（在立即创建帐户？单击“否”，然后下载 zip 文件）。

问题如下：

我需要保存用户所做的一切：例如，如果他添加了 5 个按钮并保存了它，下次当他打开保存的文件时，他会在保存它们的同一位置看到 5 按钮。 这将允许用户使用相同的程序将文件发送给另一个人，然后另一个人查看创建的文件。

---

由于误解（下面的评论），我将在上面的第二个链接中发布一些代码。但问题是我找不到任何代码来执行我所要求的操作。伙计们，我不知道如何开始，我的意思是我知道如何从图片框或一些文本中保存图像，但按钮数组是另一回事。

这是代码简单的示例代码，或者您可以下载我发布的第二个文件并编译它。

您没有提供太多信息，我不会下载您的代码。但是您可以创建一个类来表示按钮可以保存的属性（例如位置/大小/文本）并序列化此类的集合。 Google .NET 序列化并且有数百个关于该主题的链接。您可以序列化数组并轻松地从文件中反序列化它，以动态取回所有按钮，然后循环遍历反序列化的集合并将它们添加回您的表单。
