# String

### General

The string data type contains data in textual format and can hold a number of unicode characters. A detailed explanation of the string data type can be found in the  [String Data-Type](https://learn.microsoft.com/en-us/dotnet/visual-basic/language-reference/data-types/string-data-type) article of the Visual Basic .NET language documentation.

### Constants

Constant string values have to be enclosed in double-quotes; the following expression returns the string *Hello World*:

          Mail & Deploy Expression

          

"Hello World"

### Operators

The string data type supports the following operators:

#### & (Concatenation)

You can concatenate two strings by using the *&* operator. The following example combines two string constants:

          Mail & Deploy Expression

          

"Hello " & "World"

The following expression returns the constant string Today is: concatenated with the current [Date-Time](/release34/docs/date-time) formatted to a string with a [Format String](/release34/docs/format-strings) of *dd.MM.yyyy* (e.g. Today is: *31.12.2021*) using the [Format](/release34/docs/format) function:

          Mail & Deploy Expression

          

"Today is: " & Format(DateTime.Today, "dd.MM.yyyy")
