Description
Returns the string representation of the value stored in the TValue record.
Call ToString to obtain a string that represents the value stored in the TValue record. Each stored types of values have different string representations. For example, the string representation of a stored integer is actually the same as the one obtained by a call to IntToStr method.
When you call the .ToString() member, an empty TValue record returns the string '(empty)' and not '', see examples in the following table.
