Patterns.FieldGet Active Pattern (F#)

Recognizes expressions that represent getting a static or instance field.

Namespace/Module Path: Microsoft.FSharp.Quotations.Patterns

Assembly: FSharp.Core (in FSharp.Core.dll)

// Signature:
( |FieldGet|_| ) : (input:Expr) -> (Expr option * FieldInfo) option

input

Type: Expr

The input expression to match against.

The formal return type is (Expr option * FieldInfo) option. The option indicates whether the input results in a match. In a pattern matching expression, the input is decomposed, upon a successful match, into a tuple of two elements. The tuple contains an option that contains either an expression that represents the instance for an instance field, or None if the field is static. The second element of the tuple is a FieldInfo object that represents the field.

This function is named FieldGetPattern in the .NET Framework assembly. If you are accessing the member from a .NET Framework language other than F#, or through reflection, use this name.
