TypeConverter typeconv= TypeDescriptor.GetConverter(typeof(int));
Console.WriteLine(typeconv.IsValid("@@ASDF@#R53456+4A"));
Console.WriteLine(typeconv.IsValid("123"));
Console.WriteLine(typeconv.IsValid("12344"));
Console.WriteLine(typeconv.IsValid("99999999999999999999999999999999999999999999999999999999999"));

How to use TypeConverter

This is not error. Basically it checks only type of the argument. String is valid for conversion so this method returns true.
If you want safely convert from string to integer you must wrap int.Parse() in try...catch section or if you use FM2.0 use int.TryParse()
