Patterns.TryFinally Active Pattern (F#)

Recognizes expressions that represent a try...finally construct.

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

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

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

input

Type: Expr

The input expression to match against.

The formal return type is (Expr * Expr) option. The option type indicates whether the input expression results in a match. In a pattern matching expression, the input expression is decomposed, upon a successful match, into a tuple of two expressions. The first expression represents the code in the try block. The second expression represents the code in the finally block.

This function is named TryFinallyPattern 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.
