在WinForms C中获得集中控制的最快方法?

您可以使用以下方法获取窗口句柄:

  [DllImport("user32.dll")]
  private static extern IntPtr GetFocus();

然后,您可以获取与该句柄关联的.NET控件(如果有一个句柄的话) Control.FromHandle .

找到了一些有用的东西:

[DllImport("user32.dll")]
static extern IntPtr GetFocus();

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
    IntPtr wndHandle = GetFocus();
    Control focusedControl = FromChildHandle(wndHandle);
    if(focusedControl is DevExpress.XtraEditors.TextBoxMaskBox)
    {
       return base.ProcessCmdKey(ref msg, keyData);
    }
    ...
}
