是否可以迭代按钮并设置可见性？ [英] Is it possible to iterate through buttons and set visibility?

问题描述

我有20个按钮的winform。加载表格是否可以这样：

  for （i =  1 ; i< =  20 ; i ++）
  if （ somevalue ==  1 ）
 {
 button（i）.Visible =  true  ; 
} 
  else  
 {
 button（i）.Visible = 假; 
} 

somevalue是对Excel中值的引用。



所以我想要基于匹配值可见或隐藏的按钮。此匹配值存储在外部（excel）文档中。



我尝试过：



基本上我想设置按钮对用户设置的可见性，但是我无法管理。我在C＃中寻找正确的代码，但仍然没有任何成功。

解决方案

是：

  foreach （控制c 在控件中）
 {
按钮b = c  as 按钮; 
  if （b！=  null ）
 {
 b。 Visible = someValue ==  1 ; 
} 
} 

如果您的按钮位于容器（如Panel）中，那么您可能只需要检查panel.Controls集合，或者递归所有c.Collections以查找它们。

I have a winform with 20 buttons. Is something like this possible on loading form:

for(i=1; i<=20; i++)
    if(somevalue == 1)
    {
        button(i).Visible = true;
    }
    else
    {
        button(i).Visible = false;
    }

"somevalue" is a reference to a value in Excel.

So I want buttons visible or hidden based on a matching value. This matching value is stored in an external (excel) document.

What I have tried:

Basically I want to set visibility of buttons to user settings but that I can not manage. I am looking for the correct code in C# but still without any succes.

解决方案

Yes:

foreach (Control c in Controls)
   {
   Button b = c as Button;
   if (b != null)
      {
      b.Visible = someValue == 1;
      }
   }

If your buttons are within a container such as a Panel, then you may need to check just the panel.Controls collection, or recurse all c.Collections to find them.
