Gets a value that indicates whether this is a public method.

Namespace: System.Reflection
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.

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
' This example produces the following output:
' 
'Public? Method or Constructor Description
' True System.String ToString()
' True Boolean Equals(System.Object)
' True Int32 GetHashCode()
' True System.Type GetType()
' False Void Finalize()
' False System.Object MemberwiseClone()
' False Void .ctor()
' False Void .ctor(Int32)
' True Void .ctor(System.String)
using System;
using System.Reflection;
using System.Collections.Generic;
class Example
{
 public static void Demo(System.Windows.Controls.TextBlock outputBlock)
 {
 BindingFlags instanceAll = BindingFlags.Public | BindingFlags.NonPublic
 | BindingFlags.Instance;
 Type t = typeof(Example);
 List<MethodBase> ctorsAndMethods = 
 new List<MethodBase>(t.GetMethods(instanceAll));
 foreach( ConstructorInfo c in t.GetConstructors(instanceAll) )
 {
 ctorsAndMethods.Add(c);
 }
 outputBlock.Text += "Public? Method or Constructor Description\n";
 foreach(MethodBase m in ctorsAndMethods)
 {
 outputBlock.Text += String.Format(" {0,-6} {1}\n",
 m.IsPublic, m.ToString());
 }
 }
 // Example constructors.
 //
 private Example() {}
 protected Example(int input) {}
 public Example(string name) {}
}
/* This example produces the following output:
