我在VS2008环境中使用C＃。
我有一个名为frmStrategy5YrPlan的表单，其中包含一个数据网格视图，用于填充数据，然后允许用户键入新的预测数据。完成后，用户将单击一个按钮上传他们输入的新数据，我希望显示另一个表单，要求他们确认他们要这样做（因为该过程会删除所有旧数据并替换为'我进入了。）
我总是被表单欺骗，但基本上我希望我的初始表单加载第二个表单，评估用户是否选择确认加载数据（或不加载），然后使用初始表单中的代码处理数据。
这是我的初始形式，今天工作正常而没有调用第二种形式（我正在询问）。下面是初学者的第二种形式的代码和我添加的按钮的工作方式，只是试图让两种形式相互交流。在另一部分中调用表单时，总是让我感到困惑。我对MDIParents不太熟悉，但我在这里尝试过，我的初始表单没有设置为一个，所以我不确定这是否是解决方案。

this.ConfirmForm.Top = this.Height / 3 - this.ConfirmForm.Height / 2;

只需使用消息框并在其上显示提示按钮并注意成功。
MessageBox.Show("Are you sure?", "Confirm", MessageBoxButtons.OKCancel, MessageBoxIcon.Error);

上面的答案是一个很好的方法，但如果由于某种原因你可能会显示一些额外的信息，并且需要的不仅仅是一个消息框，你可以使用Form.ShowDialog http://msdn.microsoft.com/en-us/library/system.windows.forms.form.showdialog(v=VS.71).aspx
我正在工作，所以没有VS向你展示一个有效的例子，但是如果你需要的话，只需要搜索一个教程。
当您需要打开第二个表单时，从第一个表单
if（form2.ShowDialog = DialogResult.OK） {
}
