Patterns.PropertyGet Active Pattern (F#)

Recognizes expressions that represent the reading of a static or instance property, or of a non-function value declared in a module.

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

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

// Signature:
( |PropertyGet|_| ) : (input:Expr) -> (Expr option * PropertyInfo * Expr list) option

input

Type: Expr

The input expression to match against.

The formal return type is (Expr option * PropertyInfo * Expr list) 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 that has three elements. The first element is an optional expression that represents the instance. For a static property, this option is None. The second element is a PropertyInfo object that represents the property. The third element is a list that contains the arguments of the get accessor, which is used for indexed properties.

This function is named PropertyGetPattern 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.
