Concatenation Operators
VB .NET has two string concatenation operators:
-
& The ampersand symbol is the recommended concatenation operator. It is used to bind a number of string variables together, creating one string from two or more individual strings. Any nonstring variable or expression is converted to a string prior to concatenation (even if
OptionStrictis on). Its syntax is:result = expression1 & expression2...-
+ Although in principle the
+sign is identical to the&concatenation operator, it also doubles as the addition operator. Hence, as Microsoft states:When you use the + operator, you may not be able to determine whether addition or string concatenation will occur. Use the & operator for concatenation to eliminate ambiguity and provide self-documenting code.
