When overridden in a derived class, searches for the specified method whose parameters match the specified argument types and modifiers, using the specified binding constraints and the specified calling convention.
Assembly: mscorlib (in mscorlib.dll)
protected abstract MethodInfo GetMethodImpl( string name, BindingFlags bindingAttr, Binder binder, CallingConventions callConvention, Type types, ParameterModifier modifiers )
- Type: System.Reflection.BindingFlags
A bitmask comprised of one or more BindingFlags that specify how the search is conducted.
Zero, to return null.
- Type: System.Reflection.Binder
A Binder 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.
A null reference (Nothing in Visual Basic), to use the DefaultBinder.
- Type: System.Reflection.CallingConventions
The CallingConventions 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.
- Type: System.Type
An array of Type objects representing the number, order, and type of the parameters for the method to get.
An empty array of the type Type (that is, Type types = new Type) to get a method that takes no parameters.
A null reference (Nothing in Visual Basic). If types is null, arguments are not matched.
More than one method is found with the specified name and matching the specified binding constraints.
name is null.
types is multidimensional.
modifiers is multidimensional.
types and modifiers do not have the same length.
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 or BindingFlags.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 and protected methods) in the search.
Specify BindingFlags.FlattenHierarchy to include public and protected 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 of name.
BindingFlags.DeclaredOnly to search only the methods declared on the Type, not methods that were simply inherited.
See System.Reflection.BindingFlags for more information.
