How to solve '...is a 'type', which is not valid in the given context'? (C#)

Question

The following code produces the error:

Error : 'CERas.CERAS' is a 'type', which is not valid in the given context

Why does this error occur?

using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WinApp_WMI2
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            CERas.CERAS = new CERas.CERAS();
        }
    }
}

Answer 1

Change

private void Form1_Load(object sender, EventArgs e) 
    { 
        CERas.CERAS = new CERas.CERAS(); 
    } 

to

private void Form1_Load(object sender, EventArgs e) 
    { 
        CERas.CERAS c = new CERas.CERAS(); 
    } 

Or if you wish to use it later again

change it to

using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 

namespace WinApp_WMI2 
{ 
    public partial class Form1 : Form 
    { 
        CERas.CERAS m_CERAS;

        public Form1() 
        { 
            InitializeComponent(); 
        } 

    private void Form1_Load(object sender, EventArgs e) 
    { 
        m_CERAS = new CERas.CERAS(); 
    } 
} 


}
