从主窗体打开已创建的窗体



我有两个主窗口和其他窗口，我将其添加到我的项目中。第二种形式有一些内容buttons, rich text boxes, label和e.t.c。我想打开第二个窗口，使用按钮单击从主窗体，我使用以下代码：

private void button_Click(object sender, EventArgs e)
{
Exam frm= new Exam();
frm.ShowDialog();
}

比程序弹出一个新窗口，但没有内容，我已经在第二个窗口中添加了内容。请帮助某人

:)这是Exam.Designer.cs文件：

一切都很好，应该是这样的吗？

在构造函数中调用方法InitializeComponent((。

public Exam()
{
InitializeComponent() 
}

不要使用ShowDialog，而是尝试只使用 .显示((;

private void button_Click(object sender, EventArgs e)
{
Exam frm= new Exam();
// frm.ShowDialog();
frm.Show();
}
