.NET Core 2.0 By Example

Handling data – tuples, lists, record types, and data manipulation

F# supports many data types, for example:

• Primitive types: bool, int, float, string values.
• Aggregate type: class, struct, union, record, and enum 
• Array: int[], int[ , ], and float[ , , ]
• Tuple: type1 * type2 * like (a,1,2,true) type is—char * int * int * bool
• Generic: list<’x>, dictionary < ’key, ’value>

In an F# function, we can pass one tuple instead of multiple parameters of different types. Declaration of a tuple is very simple and we can assign values of a tuple to different variables, for example:

let tuple1 = 1,2,3// assigning values to variables , v1=1, v2= 2, v3=3let v1,v2,v3 = tuple1// if we want to assign only two values out of three, use “_” to skip the value. ...
