更改活动表单以显示另一种表单

Question

I have a Form1 and another one that I added. Form1 is being run by program.cs at the start. I need to hide Form1 and show options form by the press of a button.

    private void submitPassword_Click(object sender, EventArgs e)
    {
        options optionForm = new options();
        optionForm.Show();
    }

the above code opens the options form on top, but I need it to replace the current form. how can I achieve this?

Answer 1

在显示新窗体之前使用this.Close()隐藏当前窗体并确保使用无参数Application.Run因此当您关闭它的主窗体时，程序不会关闭。

Answer 2

You can use "Hide" and "Show" method :

private void submitPassword_Click(object sender, EventArgs e)

{

    options optionForm = new options();

    this.Hide();

    optionForm.Show();
}

Answer 3

private void submitPassword_Click(object sender, EventArgs e)
{
    options optionForm = new options();
    optionForm.Show();
    this.Hide();
}

Similar solutions where one form calls and acts on another... Such as this one I answered for another. You could do a similar process... pass in your first form to the second... Then show the second... Then, you could HIDE your first form (via this.Hide() ). Then, in your second form, when you click whatever button to select your choice, and need to return back to the first form, you could then use the original form's reference passed INTO the second form to re-Show it, such as in the click on the second form...

this.PreservedForm.Show();  // re-show original form
this.Close();   // and CLOSE this second form...
