有两种方法，但最简单的方法可能只是在Form.Controls集合上使用For Each循环。在你检查每个控件并检查它是否是一个按钮时，启用/禁用它们所有这些都是一件简单的事情，而不需要参考这些名称。

你能给我一个简单的代码吗？对于winform而不是WPF ..

There are a couple of ways, but the easiest way is probably just to use a For Each loop on the Form.Controls collection. Of you examine each control and check if it is a button, it's a simple matter to enable / disable all of them without referencing the names at all.

"Can you provide me a simple code please ? for winform not WPF.."

Public Sub EnableControls(controls As Control.ControlCollection, enable As Boolean)
	For Each c As Control In controls
		c.Enabled = enable
		EnableControls(c.Controls, enable)
	Next
End Sub

然后从Form类中调用它：

Then call it from your Form class with:

EnableControls(Controls, True)

放入所有按钮在面板（或任何其他容器，如 GroupeBox 等），只需启用此一个。

（如果你的设计中可能的话）

Put all your Buttons in a Panel (or any other Container, like GroupeBox, etc) and just enable this one.
(if its possible in your Design)

private void Form1_Load(object sender, EventArgs e)
{
 System.Windows.Forms.Control.ControlCollection controls = this.Controls;

  foreach(Control ctrl in controls)
  {
     if (ctrl is Button)
     {
        ctrl.Enabled = false;
     }
  }
}
