F# String

In F#, strings are represented as a series of Unicode characters. String values in F# are immutable, which means that once a string is created it cannot be modified.

Syntax

In F#, strings are enclosed in double quotes, like this:

let myString = "Hello World!"

Example

Here's an example that shows how to create and print a string in F#:

let myString = "Hello World!"
printfn "%s" myString

Output

The output of the above code will be:

Hello World!

Explanation

In the above example, we first create a string variable named myString and assign it the value "Hello World!". We then use the printfn function to print the value of myString to the console.

Use

Strings are used in various contexts, such as:

• Displaying text to the user
• Manipulating and processing text
• Storing data in configuration files

Important Points

Here are some important points to keep in mind while working with strings in F#:

• Strings are immutable, i.e., once a string is created, it cannot be modified.
• F# provides a set of functions and operators to work with strings such as + for concatenation, Length for finding the length of a string, Substring for extracting a substring, Replace for replacing a substring, etc.

Summary

F# strings are immutable and represented as a series of Unicode characters. They are enclosed in double quotes, and various functions and operators are available to work with them. F# strings are used in various contexts, such as displaying, manipulating, and storing data.
