Question

have you any alternative to these code, i want a more generic code
I tried Convert class but with no success

        public object convert(Type type, string value)
        {
            object r = null;
            if (type == typeof(bool))
            {
                r = bool.Parse(value);
            }            
            else if (type == typeof(int))
            {
                r = int.Parse(value);
            }
            else if (type == typeof(string))
            {
                r = value;
            }

            return r; 
        }

Answer 1

var conv = TypeDescriptor.GetConverter(type);
return conv.ConvertFromInvariantString(value);

Other conversion operations exist if you don’t want “invariant”. It depends on your needs. See also ConvertFromString if you want locale settins to apply, etc.
