Attributes Property

MethodBase.Attributes Property

Gets the attributes associated with this method.

Namespace:  System.Reflection
Assemblies:   mscorlib (in mscorlib.dll)
  System.Reflection (in System.Reflection.dll)

'Declaration
Public MustOverride ReadOnly Property Attributes As MethodAttributes

Property Value

Type: System.Reflection.MethodAttributes
One of the MethodAttributes values.

Implements

_MethodBase.Attributes

All members have a set of attributes, which are defined in relation to the specific type of member.

To get the MethodAttributes, first get the type. From the type, get the method. From the method, get the MethodAttributes.

Notes to Implementers

Use the Attributes property to determine whether a method is public, private, final, virtual, and so on.

The following code example displays the attributes of the user-defined method Mymethod.

Imports System
Imports System.Reflection
Imports Microsoft.VisualBasic

Class AttributesSample

    Public Sub Mymethod(ByVal int1m As Integer, ByRef str2m As String, ByRef str3m As String)
        str2m = "in Mymethod" 
    End Sub 'Mymethod

    Public Shared Function Main(ByVal args() As String) As Integer
        Console.WriteLine("Reflection.MethodBase.Attributes Sample")

        ' Get the type. 
        Dim MyType As Type = Type.GetType("AttributesSample")

        ' Get the method Mymethod on the type. 
        Dim Mymethodbase As MethodBase = MyType.GetMethod("Mymethod")

        ' Display the method name.
        Console.WriteLine("Mymethodbase = {0}.", Mymethodbase)

        ' Get the MethodAttribute enumerated value. 
        Dim Myattributes As MethodAttributes = Mymethodbase.Attributes

        ' Display the flags that are set.
        PrintAttributes(GetType(System.Reflection.MethodAttributes), CInt(Myattributes))
        Return 0
    End Function 'Main

    Public Shared Sub PrintAttributes(ByVal attribType As Type, ByVal iAttribValue As Integer)
        If Not attribType.IsEnum Then
            Console.WriteLine("This type is not an enum.")
            Return 
        End If 
        Dim fields As FieldInfo() = attribType.GetFields((BindingFlags.Public Or BindingFlags.Static))
        Dim i As Integer 
        For i = 0 To fields.Length - 1
            Dim fieldvalue As Integer = CType(fields(i).GetValue(Nothing), Int32)
            If (fieldvalue And iAttribValue) = fieldvalue Then
                Console.WriteLine(fields(i).Name)
            End If 
        Next i
    End Sub 'PrintAttributes
End Class 'AttributesSample

This code produces the following output:

Reflection.MethodBase.Attributes Sample

Mymethodbase = Void Mymethod(Int32, System.String ByRef, System.String ByRef)
