Question

我在单击按钮时打开另一个表单，但在执行此操作时无法决定如何关闭当前表单。这是代码：

private void nextSportButton_Click(object sender, EventArgs e)
{
    for (int i = 0; i < Form1.sportsAdded; i++)
    {
        if (Form1.sportOpened == i)
        {
            Form1.IDNumber = Form1.sportIDArray[i];
            OutputForm OutputForm = new OutputForm();
            OutputForm.ShowDialog();
        }

        this.Close();
    }
}

Answer 1

调用OutputForm.ShowDialog（）等待，直到OutputForm关闭，然后才返回执行更多代码。您想要使用OutputForm.Show（）。

注意：如果“this”是您的应用程序的主要表单（显示的第一个表单），关闭“this”将终止整个应用程序。

Answer 2

首先隐藏当前表单，打开新表单后不要关闭，

this.Hide();

Form1.IDNumber = Form1.sportIDArray[i];
OutputForm OutputForm = new OutputForm();
OutputForm.ShowDialog();

使用@font-face { font-family: 'Lato'; font-style: normal; font-weight: 300; src: local('Lato Light'), local('Lato-Light'), url(http://fonts.gstatic.com/s/lato/v11/EsvMC5un3kjyUhB9ZEPPwg.woff2) format('woff2');
