所以我有一个表单创建另一个表单并使用Form.ShowDialog()调用它，但是在运行期间的某个时刻新表单消失了。我可以告诉它仍在运行，因为我设置了一个计时器，完成后会显示一个消息框。消息框仍然在分配的时间后显示，但表单不再可见。
要调用我使用此代码的表单：
Player currentUser = new Player(); //Player is a class I've created
private void Game(int PlayerCount)
{
Current.Hide();
for (int i = 0; i < PlayerCount; i++)
{
currentUser = GloVar.CurrentPlayers[i];
CashBuilder cb = new CashBuilder(currentUser);
cb.ShowDialog();
}
}
表格＆＃39; cb＆＃39;显示，我可以与它进行交互，直到我按下按钮。 表格中有一种方法可以检查答案（有四个按钮，一个是正确的）是正确的。
private void IsCorrect(int i)
{
if (CorrectAnswer == i)
{
lblFeedback.Text = "Correct.";
AnsweredCorrectly++; //add to the answered correctly list
Timer2.Start(); //this timer is used to increment a value of money, it does not call on anything else and lasts 1.5 seconds.
}
else
{
lblFeedback.Text = correctAnswer;
}
QuestionsAnswered++; //add to questions answered
Generate_Question(); //bring a new question
}
如果答案在正确和不正确之间交替，则表格SEEMS（我无法澄清100％）保持可见。 但是，如果我回答正确然后更正（或不正确和不正确），表格就会消失。
我有一种关闭表单的方法，但是在计时器启动之前不会触及。
我已经搜索了大约一个星期来找到解决方案，尝试了多个线程（让线程工作但仍然遇到了这个问题），我无法想到其他任何事情。

答案 0 :(得分：0)
部分答案，因为我无法发表评论，但是有没有理由你调用cb.ShowDialog（）而不是cb.Show（）？您描述的行为听起来像消息框的行为（请参阅备注部分中的here）
我的第一个想法是，当你给出两个连续正确（或不正确）的答案时，它就像一个消息框并返回cb.DialogResult.Yes（或.No）。消息框不会像表单一样关闭，它们会隐藏，直到调用.Dispose（）。
