Question

I always get this problem when I link forms in C#.
Here’s the code of the first form:

using ybird;

public partial class form1 : Form
{
    private void linkLabel1_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
    {
        try
        {
            register form = new register();
            register.Show();
        }
        catch (Exception w)
        {
            MessageBox.Show(w.Message, Application.ProductName);
        }
    }
 }

And here’s the code for the Register.cs:

namespace ybird
{
    public partial class register : Form
    { 
    }
}

what did I do wrong?

Answer 1

This will not work, as Show is an instance method, not a static mathod:

register form = new register();
register.Show();

You probably meant:

register form = new register();
form.Show();

Note:

Your naming is non standard – types in .NET are normally in PascalCase – to be consistent, your should name the class Register. Additionally, using the variable form is not very descriptive – registerForm would be better.
