 property bool IsReusable { bool get(); };
public bool IsReusable { get; }
member this.IsReusable : bool
Public ReadOnly Property IsReusable As Boolean

屬性值

如果 IHttpHandler 執行個體可重複使用,則為 true,否則為 falsetrue if the IHttpHandler instance is reusable; otherwise, false.

範例

下列程式碼範例會將四行的文字寫入 HTTP 輸出資料流,以名為 handler.aspx 頁面的用戶端要求的回應。The following code example writes four lines of text to the HTTP output stream in response to a client request for a page named handler.aspx. Handler.aspx 的所有要求都由MyHttpHandler命名空間中的類別HandlerExample包含在組件 HandlerTest.dll。All requests for handler.aspx are serviced by the MyHttpHandler class in the namespace HandlerExample contained in the assembly HandlerTest.dll.

// Name this C# file HandlerTest.cs and compile it with the
// command line: csc /t:library /r:System.Web.dll HandlerTest.cs.
// Copy HandlerTest.dll to your \bin directory.

using System.Web;

namespace HandlerExample
{
   public class MyHttpHandler : IHttpHandler
   {
      // Override the ProcessRequest method.
      public void ProcessRequest(HttpContext context)
      {
         context.Response.Write("<H1>This is an HttpHandler Test.</H1>");      
         context.Response.Write("<p>Your Browser:</p>");
         context.Response.Write("Type: " + context.Request.Browser.Type + "<br>");
         context.Response.Write("Version: " + context.Request.Browser.Version);
      }

      // Override the IsReusable property.
      public bool IsReusable
      {
         get { return true; }
      }
   }
}

備註

您明確設定IsReusable屬性,以true或是false由您提供程式碼會覆寫IsReusable屬性存取子 (getter)。You explicitly set the IsReusable property to true or false by code you provide that overrides the IsReusable property accessor (getter).
