O exemplo de código a seguir demonstra como aplicar programaticamente o WebResourceAttribute atributo de metadados para marcar o assembly para os recursos que serão atendidos.

using System;
using System.Web;
using System.Web.UI;
using System.Security.Permissions;

[assembly: WebResource("Samples.AspNet.CS.Controls.script_include.js", "application/x-javascript")]
namespace Samples.AspNet.CS.Controls
{
    [AspNetHostingPermission(SecurityAction.Demand, Level = AspNetHostingPermissionLevel.Minimal)]
    public class ClientScriptResourceLabel
    {
        // Class code goes here.
    }
}

Imports System.Web
Imports System.Web.UI
Imports System.Security.Permissions

<Assembly: WebResource("Samples.AspNet.VB.Controls.script_include.js", "application/x-javascript")> 
Namespace Samples.AspNet.VB.Controls

    <AspNetHostingPermission(SecurityAction.Demand, Level:=AspNetHostingPermissionLevel.Minimal)> _
    Public Class ClientScriptResourceLabel

        ' Class code goes here.

    End Class

End Namespace

Este exemplo requer um arquivo JavaScript nomeado Script_include.js, com o seguinte conteúdo:

function DoClick() {Form1.Message.value='Text from resource script.'}

Compile o Script_include.js arquivo como um recurso no Samples.AspNet.CS.Controls assembly que contém a ClientScriptResourceLabel classe.

Comentários

O RegisterClientScriptResource método é usado ao acessar recursos compilados de assemblies por meio do manipulador HTTP WebResource.axd. O RegisterClientScriptResource método registra o script com o Page objeto e impede scripts duplicados. Esse método encapsula o conteúdo da URL do recurso com um <script> bloco de elementos.
