Convert functions to C#

[Memnoch1207]

I wrote this functions while doing ASP programming, but now that I am doing C# programming, I was wondering if it would be possible to convert my ASP functions into C#? They are primarily for database actions (i.e. opening, querying, closing)

function db_open(connectionStringPayload)
   if isObject(objConn) then
      if objConn.state = 0 then
         set objConn = server.createObject("ADODB.CONNECTION")
         objConn.open connectionStringPayload
         db_open = true
      else
         db_open = false
      end if
   else
      set objConn = server.createObject("ADODB.CONNECTION")
      objConn.open connectionStringPayload
      db_open = true
   end if
end function
