C# - 在运行时填充数据结构,并引用设计时添加到 TableLayoutPanel 的按钮

发布于 2024-08-10 11:05:18 字数 560 浏览 4 评论 0原文

我使用的是 Visual C# 2008 Express 版本。

如果在设计时我有一个表单 [myMainForm],
我添加了一个 TabControl [myTabControl],
myTabControl 有一个 tabPage [myTabPage],
并在此 tabPage 中添加了一个 tableLayoutPanel [myTableLayoutPanel],
我在 myTablelayoutPanel 中添加了十个按钮(button1、button2、button3 等)。

在运行时,我想用对我添加到 myTableLayoutPanel 的所有十个按钮的引用来填充数据结构。我希望以最简单、最有效的方式处理对按钮的引用。 for...next 循环与数组结合是解决该问题的最佳方法吗?

我意识到我可以以编程方式将按钮添加到面板中,但如果我这样做,我还必须在代码中调整它们的视觉设置,我宁愿避免这样做,以便使我的代码尽可能干净和简单。

如果有人可以发布几行代码来让我继续下去,我将不胜感激。

感谢您花时间阅读本文。快乐编码。

问候,

I am using Visual C# 2008 Express edition.

If at design time I have a form [myMainForm],
to which I have added a TabControl [myTabControl],
and myTabControl has a single tabPage [myTabPage],
and to this tabPage I have added a tableLayoutPanel [myTableLayoutPanel],
and to myTablelayoutPanel I have added ten buttons (button1, button2, button3, etc).

At runtime I want to populate a data structure with references to all the ten buttons I have added to myTableLayoutPanel. I want to work with the references to the buttons in the simplest, most efficient way possible. Is a for...next loop in conjunction with an array the best approach to tackle the problem?

I realise that I could add the buttons programmatically to the panel, but if I do that I will have to tweak their visual settings in code as well which I would rather avoid in order to keep my code as clean and simple as possible.

If someone could post a few lines of code to get me going on this I'd be grateful.

Thanks for taking the time to read this. Happy coding.

Regards,

The Thing

在 C#3(在 VS 2008 中)中,您可以使用数组初始值设定项语法设置编译时数组:

var buttons = new [] { button1, button2, ... button10 };

或者,您可以反映所有字段并过滤按钮,沿着

using System.Linq;

// tlp being your TablelayoutPanel instance
var buttons = tlp.GetType().GetFields().Select(f => f.GetValue(tlp)).Where(v => v is Button).ToArray();

This gets all the Buttons --如果您想过滤掉除某些已知命名之外的这些字段,您可能需要在 Select 之前添加 Where(f => SomeTestOn(f.Name)) 过滤器图案表明它们是您真正想要的按钮。

In C#3 (in VS 2008), you could set up a compile-time array using the array initializer syntax:

var buttons = new [] { button1, button2, ... button10 };

alternatively, you could reflect on all the fields and filter the buttons, along the lines of

using System.Linq;

// tlp being your TablelayoutPanel instance
var buttons = tlp.GetType().GetFields().Select(f => f.GetValue(tlp)).Where(v => v is Button).ToArray();

This gets all the buttons -- you might want to add a Where(f => SomeTestOn(f.Name)) filter before the Select if you want to filter out those fields except with some known naming pattern indicating that they are the buttons you actually want.
