I like Mike's reply better than my reply, but maybe it will explain some things about enums.

namespace MyProject
{
    public enum DatabaseType
    {
        MSSQL,
        Oracle
    }

    class MyClass
    {
       public int iDataBaseType = (int)DatabaseType.MSSQL; 
    }
}

You always have to cast the enum to the underlaying type (default is int if not specified). I don't know why they implemented it this way but oh well. My latest enum woe is that I use a guid as an enum type; a guid is a value type and is just a big number. I still like enums.
