我如何回到C＃中的上一个表格

Question

public ControlPanel(string userInfo)
{
    InitializeComponent();
    lblUserInfo.Text = userInfo;
}

I'm trying to go to the form above using the code below, an error message occurs:

there is no argument given that corresponds to the required formal parameter 'user info'

{
    this.Hide();
    ControlPanel cp = new ControlPanel();
    cp.ShowDialog();
}

Answer 1

ControlPanel constructor requires string userInfo parameter.

this.Hide();
ControlPanel cp = new ControlPanel("SomeUserInfo");
cp.ShowDialog();
