Patterns.PropertySet Active Pattern (F#)
Recognizes expressions that represent setting a static or instance property, or setting a non-function value declared in a module.
Namespace/Module Path: Microsoft.FSharp.Quotations.Patterns
Assembly: FSharp.Core (in FSharp.Core.dll)
// Signature:
( |PropertySet|_| ) : (input:Expr) -> (Expr option * PropertyInfo * Expr list * Expr) option
Parameters
input
Type: ExprThe input expression to match against.
Return Value
The formal return value is (Expr option * PropertyInfo * Expr list * Expr) option. The option type 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 four elements. The first element is an option whose value is an expression that represents the instance, or None if the property is static. The second element is a PropertyInfo object that represents the property (or the module value). The third element is an expression list that represents the arguments to the set accessor, which is used for indexed properties. The fourth element is an expression that represents the value to set, which is also the right side of the assignment.
Remarks
This function is named PropertySetPattern 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.
