Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public ReadOnly Property IsPublic As Boolean

public bool IsPublic { get; }

Property Value

Type: System.Boolean
true if this method is public; otherwise, false.

Examples

The following example uses the IsPublic property to display a message that indicates whether the specified method is public.

Note:
To run this example, see Building Examples That Use a Demo Method and a TextBlock Control.

Imports System.Reflection
Imports System.Collections.Generic

Class Example

   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock) 

      Dim instanceAll As BindingFlags = BindingFlags.Public Or _
         BindingFlags.NonPublic Or BindingFlags.Instance

      Dim t As Type = GetType(Example)
      Dim ctorsAndMethods As New List(Of MethodBase)( _
         t.GetMethods(instanceAll))

      For Each c As ConstructorInfo In t.GetConstructors(instanceAll)
         ctorsAndMethods.Add(c)
      Next

      outputBlock.Text &= "Public?      Method or Constructor Description" & vbLf 

      For Each m As MethodBase In ctorsAndMethods 
         outputBlock.Text &= String.Format(" {0,-6}      {1}" & vbLf, _
            m.IsPublic, m.ToString())
      Next

   End Sub

   ' Example constructors.

   Private Sub New() 
   End Sub

   Protected Sub New(ByVal int As Integer)
   End Sub

   Public Sub New(ByVal name As String)
   End Sub

End Class
