Type::GetMethod Method (String^, BindingFlags)

Parameters

name

Type: System::String^

The string containing the name of the method to get.

bindingAttr

Type: System.Reflection::BindingFlags

A bitmask comprised of one or more BindingFlags that specify how the search is conducted.

-or-

Zero, to return null.

Return Value

An object representing the method that matches the specified requirements, if found; otherwise, null.

Implements

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, internal, 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.

If a method is overloaded and more than one overload meets the constraints specified by the bindingAttr argument, the method throws an AmbiguousMatchException exception. In the following example, an exception is thrown because:

• The TestClass type has two public instance overloads of the DisplayValue method, DisplayValue(String) and DisplayValue(String, Object[]).

• The TestClass type has two public instance overloads of the Equals method, one of which is inherited from Object: Equals(TestClass) and Equals(Object).

You can do one of the following to retrieve a specific method:

• Change the binding constraints. In the previous example, attempting to retrieve a public instance Equals method that is declared by the type and not inherited successfully retrieves Equals(TestClass).

• Call an overload of the GetMethod method that includes a types parameter which defines the types of the method's parameters.

• Call the GetMethods(BindingFlags) method to retrieve an array containing all of the methods belonging to a type that have the specified binding attributes. You can then iterate it to identify the duplicate methods named name. This approach is illustrated in the previous example's handler for the AmbiguousMatchException exception.

If the current Type represents a constructed generic type, this method returns the MethodInfo with the type parameters replaced by the appropriate type arguments.

If the current Type represents a type parameter in the definition of a generic type or generic method, this method searches the methods of the class constraint, or the methods of Object if there is no class constraint.

Note
For generic methods, do not include the type arguments in name. For example, the C# code GetMember("MyMethod<int>") searches for a member with the text name "MyMethod<int>", rather than for a method named MyMethod that has one generic argument of type int.
