[edit] String Operator

[edit] String concatenation

The "&" operator joins two strings together. Example:

Dim String1 As String = "123"
Dim String2 As String = "456"
Dim String3 As String
String3 = String1 & String2 ' Results in "123456".

This will result in String3 being equal to "123456"

The "+" operator may be used in place of "&". However, it is not recommended.

[edit] Concat

You may concatenate a number of strings:

Dim String1 As String = "Let"
Dim String2 As String = " us"
Dim String3 As String = " concatenate!"
Dim strOutput As String

strOutput = String.concat(String1,String2,String3) ' Results in "Let us concatenate!".

If you have defined a string array, such as:

Dim strArr As String() = {"I", " am", " your", " automatic", " lover."}

then all the elements of this array may be concatenated in a simple way:

strOutput = string.concat(strArr) ' Results in "I am your automatic lover."
