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
Strict is 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.
