使用类型和资源名向 Page 对象注册客户端脚本资源。
public:
void RegisterClientScriptResource(Type ^ type, System::String ^ resourceName);public void RegisterClientScriptResource (Type type, string resourceName);member this.RegisterClientScriptResource : Type * string -> unitPublic Sub RegisterClientScriptResource (type As Type, resourceName As String)参数
- type
- Type
要注册的客户端脚本资源的类型。
- resourceName
- String
要注册的客户端脚本资源的名称。

下面的代码示例演示如何以编程方式应用 WebResourceAttribute 元数据属性，以标记将提供服务的资源的程序集。
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
此示例需要一个名为 Script_include.js的 JavaScript 文件，其中包含以下内容：
function DoClick() {Form1.Message.value='Text from resource script.'}
将Script_include.js文件编译为包含 ClientScriptResourceLabel 类的Samples.AspNet.CS.Controls程序集中的资源。
注解
RegisterClientScriptResource通过 WebResource.axd HTTP 处理程序从程序集访问已编译的资源时，使用 方法。 方法 RegisterClientScriptResource 将脚本注册到 对象， Page 并防止脚本重复。 此方法使用元素块包装资源 URL <script> 的内容。
