+// System.Convert has ToType helper method for the object 
+// ToType (Type conversionType, IFormatProvider provider)
+// method. In most cases you can specify your ToType function
+// as calling 
+//
+// public Type value; // value of this data type
+// public object ToType(Type conversionType, IFormatProvider provider) {
+//    Convert.ToType (value, conversionType, provider);
+// }

+// Which is just a wrapper for your ToType methods.
