c# - VS 2008 C# 将焦点设置为仅一种形式

Question

当我的表单 (AboutForm) 显示时，我需要将焦点放在此表单上(用户应该只能单击“确定”按钮)!

VS2008 需要什么设置？

谢谢!

你想模态显示它，所以使用ShowDialog()而不是 Show()。就是这样。

例如:

using(var frm = new AboutForm()) {
    frm.ShowDialog(this);
}

重要:当使用 ShowDialog 时，关闭窗体不会 Dispose() 它，因此 using;参见 MSDN:

Unlike modeless forms, the Close method is not called by the .NET Framework when the user clicks the close form button of a dialog box or sets the value of the DialogResult property. Instead the form is hidden and can be shown again without creating a new instance of the dialog box. Because a form displayed as a dialog box is hidden instead of closed, you must call the Dispose method of the form when the form is no longer needed by your application.
