F# collection initializer syntax

Question

What is the collection initializer syntax in F#? In C# you can write something like:

new Dictionary() {
    {\"One\", 1},
    {\"two\", 2}}
         


        

Answer 1

To elaborate a bit on collection initialization in F#, here are a few examples:

read-only dictionary

dict [ (1, "a"); (2, "b"); (3, "c") ]

seq (IEnumerable)

seq { 0 .. 99 }

list

[1; 2; 3; 4; 5]

set

set [1; 2; 3; 4; 5]

array

[| 1; 2; 3; 4; 5 |]
