Reference to a non-shared member requires an object reference

Hi,
I tried to use a custom assembly, written in C#. I received the following
error:
"[BC30469] Reference to a non-shared member requires an object reference..."
Here's the detail info for the custom assembly:
*I have 2 C# files. I did not write the code. So my C# knowledge is
limited. I removed some of the code within the methods because it gets very
long. Here is the code:
--[IConvertor.cs]--
using System;
namespace sbu.convertor
{
public interface IConvertor
{
string convert(string label, string direction, string val);
string convertByUnit(string before, string after, string val, string
direction, string group, string format);
string convertByUnit2(string before, string after, string val, string
direction);
string getUnit(string usUnit, string saUnit, string direction, string
group);
string getUnit2(string usUnit, string saUnit, string direction);
}
}
--[Convertor.cs]--
using System;
using System.IO;
using System.Xml;
using System.Globalization;
namespace sbu.convertor
{
public class Convertor:IConvertor
{
private static Convertor instance;
public static IConvertor getInstance()
{
if (instance==null)
{
instance = new Convertor();
}
return instance;
}
private XmlDocument doc;
private string docSource = null;
private NumberFormatInfo format;
public Convertor()
{
if(File.Exists("C:\\Inetpub\\wwwroot\\rocks\\itapps\\sbu\\sbu_convertor\\conversion.xml"))
{
//pdu dev box
docSource = "C:\\Inetpub\\wwwroot\\rocks\\itapps\\sbu\\sbu_convertor\\conversion.xml";
}
if(File.Exists("C:\\Inetpub\\wwwroot\\rocks\\itapps\\sbu\\sbu_convertor\\conversion.xml"))
{
//webdevtest
docSource = "C:\\Inetpub\\wwwroot\\rocks\\itapps\\sbu\\sbu_convertor\\conversion.xml";
}
doc = new XmlDocument();
doc.Load(docSource);
format = new NumberFormatInfo();
format.NumberDecimalDigits = 3;
format.NumberGroupSizes = new int[] {3};
format.NumberGroupSeparator = ",";
format.NumberDecimalSeparator = ".";
}
public string convert(string label, string direction, string val)
{
return (double.Parse(val)*getRatio(label,direction)).ToString();
//return "0000000000";
}
private double getRatio(string label, string direction)
{
XmlNode node = doc.SelectSingleNode("RICETEC/LABEL/CONVERSION[@.ID='"+label+"']/"+direction);
string valStr = node.InnerText;
return double.Parse(valStr);
}
public string convertByUnit(string usUnit, string saUnit, string val,
string direction, string group, string format)
{
////
}
public string convertByUnit2(string before, string after, string val,
string direction)
{
////
}
public string getUnit(string usUnit, string saUnit, string direction,
string group)
{
///
}
public string getUnit2(string usUnit, string saUnit, string direction)
{
///
}
public string convertTemp(string val, string direction)
{
///
}
}
}
* Here is how I complied it:
csc /t:library /out:bin/sbu_convertor.dll *.cs
Thanks in advance. JLI found a solution. I simply added the class and instance names in the
Reference tab. That fixed it.
