Indicates whether two specifed String objects have the same value.
bool String::operator+( String^ str1,
String^ str2)
This operator creates a String^ object that contains the data from the two operands. Use it for convenience when extreme performance is not critical. A few calls to "+" in a function will probably not be noticeable, but if you are manipulating large objects or text data in a tight loop, then use the standard C++ mechanisms and types.
