How to convert Shared sub (vb.net) to C#?

Question

Hi

 

I'm new with C# and I want to convert this vb.net code to C# but i get two errors like "a namespace doesn't not contain members ..." on the line "Public Class check" and "expected classes ..." on the line "Public Shared"

 

Thanks for help.

 

Here the vb.net code:

Imports Microsoft.VisualBasic
Public Class check
Public Shared Sub ok()
Dim ok As HttpCookie
ok = HttpContext.Current.Request.Cookies("ok")
Try
If Not ok.Value = "y" Then
End If
Catch ex As Exception
Dim jv As String
jv = "<script language='javascript'>" _
& " alert('First log in.');" _
& " window.location.href='start.aspx';" _
& "</script>"
HttpContext.Current.Response.Write(jv)
End Try
End Sub
End Class

And here my C# code:

using System;
using System.Web.UI.WebControls;
Public Class check
{
public static void ok()
{
HttpCookie ok;
ok = HttpContext.Current.Request.Cookies("ok");
try
{
if (!(ok.Value == "y"))
{}
}
catch (Exception ex)
{
string jv;
jv = "<script language='javascript'>" + " alert('First log in.');" + " window.location.href='start.aspx';" + "</script>";
HttpContext.Current.Response.Write(jv);
}
}
}
