System.Web.Hosting
程序集:
System.Web.dll

返回与此 ASP.NET 宿主进程关联的 ApplicationManager 对象的一个实例。

public:
 static System::Web::Hosting::ApplicationManager ^ GetApplicationManager();
public static System.Web.Hosting.ApplicationManager GetApplicationManager ();
static member GetApplicationManager : unit -> System.Web.Hosting.ApplicationManager
Public Shared Function GetApplicationManager () As ApplicationManager

返回

ApplicationManager

与运行中的 ASP.NET 宿主进程关联的 ApplicationManager 对象的一个实例。

示例

下面的代码示例使用 GetApplicationManager 该方法检索 ApplicationManager Web 应用程序的实例。


<%@ Page Language="C#" %>
<%@ Import Namespace="System.Web.Hosting" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">
  protected void Page_PreRender(object sender, EventArgs e)
  {
    ApplicationManager appManager = ApplicationManager.GetApplicationManager();
    ApplicationInfo [] appInfo = appManager.GetRunningApplications();
    GridView1.DataSource = appInfo;
    GridView1.DataBind();
  }
</script>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
  <meta http-equiv="Content-Type" content="text/html" />
  <title>Application Info sample</title>
</head>
<body>
  <form id="form1" runat="server">
    <asp:GridView ID="GridView1" runat="server">
    </asp:GridView>
  </form>
</body>
</html>

<%@ Page Language="VB" %>
<%@ Import Namespace="System.Web.Hosting" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">
  Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As EventArgs)
    Dim appManager As ApplicationManager
    appManager = ApplicationManager.GetApplicationManager()
   
    Dim appInfo As ApplicationInfo()
    appInfo = appManager.GetRunningApplications()
    
    GridView1.DataSource = appInfo
    GridView1.DataBind()
  End Sub
</script>

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
  <meta http-equiv="Content-Type" content="text/html" />
  <title>Untitled Page</title>
</head>
<body>
  <form id="form1" runat="server">
    <asp:GridView ID="GridView1" runat="server">
    </asp:GridView>
  </form>
</body>
</html>

注解

默认应用程序域中只有一个对象实例ApplicationManager由 ASP.NET 主机进程创建。 如果类的 ApplicationManager 实例不可用，该方法 GetApplicationManager 首先创建类的 ApplicationManager 实例，然后返回新创建的对象。 如果之前创建了类的 ApplicationManager 实例，该方法 GetApplicationManager 将返回现有对象。
