winform新窗体打开同时隐藏主窗体

Posted 2020-06-22

我的思路是将窗体作为参数来传递

private void button1_Click(object sender, EventArgs e)
{
Form2 f = new Form2(this);
f.Show();
this.Hide();
}

form2中代码
private Form parent;
public Form2(System.Windows.Forms.Form f)
{
InitializeComponent();
this.parent = f;
}
private void button1_Click(object sender, EventArgs e)
{
parent.Show();
this.Hide();
}

 

然而最简单的是

private void click()
{
Form2 f2=new Form2();
this.Hide();
f2.ShowDialog();
this.show();
}
