Examples

The following example defines an attribute and applies it to the example's module. When the example runs, it retrieves the attributes that were applied to the module and displays them.

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

Imports System.Reflection

' Define a module-level attribute.
<Module: MySimpleAttribute("module-level")> 

Class Example
    Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
        Dim moduleArray() As [Module] = _
            [Assembly].GetExecutingAssembly().GetModules()
        Dim myModule As [Module] = moduleArray(0)
        Dim attributes() As Object = myModule.GetCustomAttributes(True)
        For Each o As Object In attributes
            outputBlock.Text &= _
                String.Format("Found this attribute on myModule: {0}" & vbLf, o.ToString())
        Next o
    End Sub 
End Class 

'A very simple custom attribute.
<AttributeUsage(AttributeTargets.Class Or AttributeTargets.Module)> _
Public Class MySimpleAttribute
    Inherits Attribute
    Private name As String
    Public Sub New(ByVal newName As String)
        name = newName
    End Sub 
End Class 

' This example produces output similar to the following:
'
'Found this attribute on myModule: SilverlightApplication.MySimpleAttribute.

using System;
using System.Reflection;

//Define a module-level attribute.
[module: MySimpleAttribute("module-level")]

class Example
{
    public static void Demo(System.Windows.Controls.TextBlock outputBlock)
    {
        Module[] moduleArray = Assembly.GetExecutingAssembly().GetModules();
        Module myModule = moduleArray[0];
        object[] attributes = myModule.GetCustomAttributes(true);
        foreach (Object o in attributes)
        {
            outputBlock.Text += 
               String.Format("Found this attribute on myModule: {0}.\n", o.ToString());
        }
    }
}

//A very simple custom attribute.
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Module)]
public class MySimpleAttribute : Attribute
{
    private string name;

    public MySimpleAttribute(string newName)
    {
        name = newName;
    }
}

/* This example produces output similar to the following:

Found this attribute on myModule: MySimpleAttribute.
