Protected Overridable Function GetMethodImpl (name As String, genericParameterCount As Integer, bindingAttr As BindingFlags, binder As Binder, callConvention As CallingConventions, types As Type(), modifiers As ParameterModifier()) As MethodInfo
Parameters
- name
- String
The string containing the name of the method to get.
- genericParameterCount
- Int32
The number of generic type parameters of the method.
- bindingAttr
- BindingFlags
A bitwise combination of the enumeration values that specify how the search is conducted.
-or-
Default to return null
.
- binder
- Binder
An object that defines a set of properties and enables binding, which can involve selection of an overloaded method, coercion of argument types, and invocation of a member through reflection.
-or-
A null reference (Nothing
in Visual Basic), to use the DefaultBinder.
- callConvention
- CallingConventions
The object that specifies the set of rules to use regarding the order and layout of arguments, how the return value is passed, what registers are used for arguments, and what process cleans up the stack.
- types
- Type[]
An array of Type objects representing the number, order, and type of the parameters for the method to get.
-or-
An empty array of the type Type (that is, Type[] types = new Type[0]) to get a method that takes no parameters.
-or-
null
. If types
is null
, arguments are not matched.
- modifiers
- ParameterModifier[]
An array of ParameterModifier objects representing the attributes associated with the corresponding element in the types
array. The default binder does not process this parameter.
Returns
An object representing the method that matches the specified generic parameter count, argument types, modifiers, binding constraints and calling convention, if found; otherwise, null
.
Exceptions
The method needs to be overriden and called in a derived class.

Parameters
- name
- String
The string containing the name of the method to get.
- bindingAttr
- BindingFlags
A bitwise combination of the enumeration values that specify how the search is conducted.

.

. If types

, arguments are not matched.
- modifiers
- ParameterModifier[]
An array of ParameterModifier objects representing the attributes associated with the corresponding element in the types
array. The default binder does not process this parameter.
Returns
An object representing the method that matches the specified requirements, if found; otherwise, null
.
Exceptions
More than one method is found with the specified name and matching the specified binding constraints.
name
is null
.
types
is multidimensional.
-or-
modifiers
is multidimensional.
-or-
types
and modifiers
do not have the same length.
The current type is a TypeBuilder or GenericTypeParameterBuilder.
Remarks
Although the default binder does not process ParameterModifier (the modifiers
parameter), you can use the abstract System.Reflection.Binder class to write a custom binder that does process modifiers
. ParameterModifier
is only used when calling through COM interop, and only parameters that are passed by reference are handled.
If types
is null
, arguments are not matched.
The following BindingFlags filter flags can be used to define which methods to include in the search:
You must specify either
BindingFlags.Instance
orBindingFlags.Static
in order to get a return.Specify
BindingFlags.Public
to include public methods in the search.Specify
BindingFlags.NonPublic
to include non-public methods (that is, private, internal, and protected methods) in the search.Specify
BindingFlags.FlattenHierarchy
to includepublic
andprotected
static members up the hierarchy;private
static members in inherited classes are not included.
The following BindingFlags modifier flags can be used to change how the search works:
BindingFlags.IgnoreCase
to ignore the case ofname
.BindingFlags.DeclaredOnly
to search only the methods declared on the Type, not methods that were simply inherited.
See System.Reflection.BindingFlags for more information.
