NET.interfaceView

Create an IConvertible interface object from System.String .

str = System.String("Hello, world!");
itf = NET.interfaceView(str,"System.IConvertible");

System.String has methods such as ToLower which manipulate strings. The interface object has conversion methods to cast the object to different types, such as the datetime type using the ToDateTime method. Compare the output of these commands:

str.To<tab>
itf.To<tab>
