Selects a method from the given set of methods, based on the argument type.

abstract System::Reflection::MethodBase ^ SelectMethod(System::Reflection::BindingFlags bindingAttr, cli::array <System::Reflection::MethodBase ^> ^ match, cli::array <Type ^> ^ types, cli::array <System::Reflection::ParameterModifier> ^ modifiers);

abstract member SelectMethod : System.Reflection.BindingFlags * System.Reflection.MethodBase[] * Type[] * System.Reflection.ParameterModifier[] -> System.Reflection.MethodBase
Public MustOverride Function SelectMethod (bindingAttr As BindingFlags, match As MethodBase(), types As Type(), modifiers As ParameterModifier()) As MethodBase
Parameters
- bindingAttr
- BindingFlags
A bitwise combination of BindingFlags values.
- match
- MethodBase[]
The set of methods that are candidates for matching. For example, when a Binder object is used by InvokeMember, this parameter specifies the set of methods that reflection has determined to be possible matches, typically because they have the correct member name. The default implementation provided by DefaultBinder changes the order of this array.
- types
- Type[]
The parameter types used to locate a matching method.
- modifiers
- ParameterModifier[]
An array of parameter modifiers that enable binding to work with parameter signatures in which the types have been modified.
Returns
The matching method, if found; otherwise, null
.
Exceptions
For the default binder, match
contains multiple methods that are equally good matches for the parameter types described by types
. For example, the array in types
contains a Type object for MyClass
and the array in match
contains a method that takes a base class of MyClass
and a method that takes an interface that MyClass
implements.
For the default binder, match
is null
or an empty array.
-or-
An element of types
derives from Type, but is not of type RuntimeType
.
Remarks
This method should return null
if no method matches the criteria. This method controls the selection provided by the GetConstructor
and GetMethod
methods on Type
.
