问题描述

我在互联网上搜索了这个，但我找不到如何使用 C# 来完成它

I searched the internet for this but i couldn't find how to do it with C#

我想要做的是，当我点击我的 NewTab 按钮时，会出现一个新标签，其中包含与第一个标签上相同的控件.我看到了一些关于如何将 UserControl 添加到表单的信息，但 C# 没有类似的东西.

What i am trying to do is make it so that when i click on my NewTab button, a new tab appears with the same controls that were on the first tab. I saw some information on how to add a UserControl to your form, but C# doesn't have anything like that.

对于每个会说发布你的代码"的人，我没有，所以不要费心这么说，我唯一的代码是程序的代码，这对任何人都没有帮助.

And for everyone who would say "Post your code", i don't have any, so don't bother saying that, the only code i have is the code for the program and that wouldn't help anyone.

推荐答案

我已经重写了使用反射的解决方案.

EDIT

I have rewritten my solution to use reflection.

using System.Reflection;

// your TabControl will be defined in your designer
TabControl tc;
// as will your original TabPage
TabPage tpOld = tc.SelectedTab;

TabPage tpNew = new TabPage();
foreach(Control c in tpOld.Controls)
{
    Control cNew = (Control) Activator.CreateInstance(c.GetType());

    PropertyDescriptorCollection pdc = TypeDescriptor.GetProperties(c);

    foreach (PropertyDescriptor entry in pdc)
    {
        object val = entry.GetValue(c);
        entry.SetValue(cNew, val);
    }

    // add control to new TabPage
    tpNew.Controls.Add(cNew);
}

tc.TabPages.Add(tpNew);
