Press a keyboard key

[Korupt]

Hey guys I've been trying to get my web browser to load on a web page on enter but nothing seems to work here's what I'm trying to do:
Try 1

        private void comboBox1_KeyPress(object sender, KeyPressEventArgs e)
        {
            if(e.KeyChar = Keys.Enter)
            {
                webBrowser1.Navigate(comboBox1.Text);
            }
        }

VS2008 Compiler error: Cannot implicitly convert type 'System.Windows.Forms.Keys' to 'char'. An explicit conversion exists (are you missing a cast?)

Try 2

        private void comboBox1_KeyPress(object sender, KeyPressEventArgs e)
        {
            switch (e.KeyChar)
            {
                case Keys.Enter:
                    webBrowser1.Navigate(comboBox1.Text);
                    break;
            }
        }

VS2008 Compiler error: Cannot implicitly convert type 'System.Windows.Forms.Keys' to 'char'. An explicit conversion exists (are you missing a cast?)

Try 3

        private void comboBox1_KeyPress(object sender, KeyPressEventArgs e)
        {
            switch (e.KeyChar)
            {
                case Keys.Enter.ToString();
                    webBrowser1.Navigate(comboBox1.Text);
                    break;
            }
        }

VS2008 Compiler error: error CS0029: Cannot implicitly convert type 'string' to 'char'

Can anyone please please help I've been trying to find a solution for 3 hours now but nothing works
