Concatenating strings
The + operator (discussed in Chapter 3, Introduction to C# Programming) is not the only way to perform string concatenation. The static method Concat of class string (Fig. 16.7) concatenates two strings and returns a new string containing the combined characters from both original strings. Line 16 appends the characters from string2 to the end of a copy of string1, using method Concat. The statement in line 16 does not modify the original strings.
