Type.GetMethods Method (BindingFlags)

When overridden in a derived class, searches for the methods defined for the current Type, using the specified binding constraints.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

'Declaration
Public MustOverride Function GetMethods ( _
	bindingAttr As BindingFlags _
) As MethodInfo()

Parameters

bindingAttr
Type: System.Reflection.BindingFlags
A bitmask comprised of one or more BindingFlags that specify how the search is conducted.
-or-
Zero, to return Nothing.

Return Value

Type: System.Reflection.MethodInfo()
An array of MethodInfo objects representing all methods defined for the current Type that match the specified binding constraints.
-or-
An empty array of type MethodInfo, if no methods are defined for the current Type, or if none of the defined methods match the binding constraints.

Implements

IReflect.GetMethods(BindingFlags)

The GetMethods method does not return methods in a particular order, such as alphabetical or declaration order. Your code must not depend on the order in which methods are returned, because that order varies.

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. Only protected and internal methods on base classes are returned; private methods on base classes are not returned.

  • 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.DeclaredOnly to search only the methods declared on the Type, not methods that were simply inherited.

See System.Reflection.BindingFlags for more information.

NoteNote:

You cannot omit parameters when looking up constructors and methods. You can only omit parameters when invoking.

If the current T:System.Type represents a constructed generic type, this method returns the MethodInfo objects 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.

Platform Notes

Silverlight for Windows Phone Silverlight for Windows Phone

 GetMethods throws an InvalidProgramException if one of the methods returned contains a type that will not be available at run time.

The following example creates a class with two public methods and one protected method, creates a Type object corresponding to MyTypeClass, gets all public and non-public methods, and displays their names.



Imports System.Reflection
Imports System.Reflection.Emit

' Create a class having two public methods and one protected method.
Public Class MyTypeClass
   Public Sub MyMethods()
   End Sub 'MyMethods
   Public Function MyMethods1() As Integer
      Return 3
   End Function 'MyMethods1
   Protected Function MyMethods2() As [String]
      Return "hello"
   End Function 'MyMethods2
End Class 'MyTypeClass
Public Class Example
   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)

      Dim myType As Type = GetType(MyTypeClass)
      ' Get the public methods.
      Dim myArrayMethodInfo As MethodInfo() = myType.GetMethods((BindingFlags.Public Or BindingFlags.Instance Or BindingFlags.DeclaredOnly))
      outputBlock.Text &= (ControlChars.Cr + "The number of public methods is " & myArrayMethodInfo.Length.ToString() & ".") & vbCrLf
      ' Display all the public methods.
      DisplayMethodInfo(outputBlock, myArrayMethodInfo)
      ' Get the nonpublic methods.
      Dim myArrayMethodInfo1 As MethodInfo() = myType.GetMethods((BindingFlags.NonPublic Or BindingFlags.Instance Or BindingFlags.DeclaredOnly))
      outputBlock.Text &= (ControlChars.Cr + "The number of protected methods is " & myArrayMethodInfo1.Length.ToString() & ".") & vbCrLf
      ' Display all the nonpublic methods.
      DisplayMethodInfo(outputBlock, myArrayMethodInfo1)
   End Sub 'Main

   Public Shared Sub DisplayMethodInfo(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal myArrayMethodInfo() As MethodInfo)
      ' Display information for all methods.
      Dim i As Integer
      For i = 0 To myArrayMethodInfo.Length - 1
         Dim myMethodInfo As MethodInfo = CType(myArrayMethodInfo(i), MethodInfo)
         outputBlock.Text &= (ControlChars.Cr + "The name of the method is " & myMethodInfo.Name & ".") & vbCrLf
      Next i
   End Sub 'DisplayMethodInfo
End Class 'TypeMain
