PeerCollaboration.RegisterApplication 方法

定义

命名空间:

System.Net.PeerToPeer.Collaboration

程序集:

System.Net.dll

注册指定的 PeerApplication，可用于通过调用对等进行协作会话。

public:
 static void RegisterApplication(System::Net::PeerToPeer::Collaboration::PeerApplication ^ application, System::Net::PeerToPeer::Collaboration::PeerApplicationRegistrationType type);

[System.Security.SecurityCritical]
public static void RegisterApplication (System.Net.PeerToPeer.Collaboration.PeerApplication application, System.Net.PeerToPeer.Collaboration.PeerApplicationRegistrationType type);

[<System.Security.SecurityCritical>]
static member RegisterApplication : System.Net.PeerToPeer.Collaboration.PeerApplication * System.Net.PeerToPeer.Collaboration.PeerApplicationRegistrationType -> unit

Public Shared Sub RegisterApplication (application As PeerApplication, type As PeerApplicationRegistrationType)

参数

application

PeerApplication

PeerApplication，要为其在相关范围（全局、本地和链接-本地）内注册调用对等。

type

PeerApplicationRegistrationType

要执行的注册类型。 应用程序可以仅针对调用对等注册，或针对使用计算机的所有对等注册。

属性

SecurityCriticalAttribute

例外

ArgumentException

• Path传递给 application 的对象PeerApplication上的 属性为 null。

• 提供的对等应用程序实例具有与已注册应用程序相同的全局唯一 Id。 必须先注销现有注册，然后才能向提供的标识符注册新的应用程序。

ArgumentNullException

application 和 type 参数不能为 null。 必须指定这两个参数。

ArgumentOutOfRangeException

未将类型参数设置为 PeerApplicationRegistrationType 枚举中的已知值。

PeerToPeerException

在调用方登录到基础结构前，无法完成 RegisterApplication(PeerApplication, PeerApplicationRegistrationType) 操作。

示例

以下代码示例演示如何向协作基础结构注册应用程序：

// Registering Notepad.exe as a collab application with a fixed GUID.
// Note: If you're using the application to send invitations,
// the same application with the same GUID must be registered on the remote peer machine.
private static PeerApplication RegisterCollabApp()
{
    PeerApplication application = null;
    string pathToApp = "%SystemRoot%\\notepad.exe";
    Guid appGuid = new Guid(0xAAAAAAAA, 0xFADE, 0xDEAF, 0xBE, 0xEF, 0xFF, 0xEE, 0xDD, 0xCC, 0xBB, 0xAE);

    application = new PeerApplication();
    application.Id = appGuid;
    application.Path = pathToApp;
    application.Description = "Peer Collaboration Sample -- notepad.exe";
    application.PeerScope = PeerScope.All;
    application.CommandLineArgs = "n";
    application.Data = ASCIIEncoding.ASCII.GetBytes("Test");

    Console.WriteLine("Attempting to register the application \"notepad.exe\"...");
    try
    {

        PeerApplicationCollection pac = PeerCollaboration.GetLocalRegisteredApplications(PeerApplicationRegistrationType.AllUsers);
        if (pac.Contains(application))
        {
            Console.WriteLine("The application is already registered on the peer.");
        }
        else
        {
            PeerCollaboration.RegisterApplication(application, PeerApplicationRegistrationType.AllUsers);
            Console.WriteLine("Application registration succeeded!");
        }
    }
    catch (ArgumentException argEx)
    {
        Console.WriteLine("The application was previously registered with the Peer Collaboration Infrastructure: {0}.", argEx.Message);
    }
    catch (PeerToPeerException p2pEx)
    {
        Console.WriteLine("The application failed to register with the Peer Collaboration Infrastructure: {0}", p2pEx.Message);
    }
    catch (Exception ex)
    {
        Console.WriteLine("An unexpected exception occurred when trying to register the application: {0}.", ex.Message);
    }
    return application;
}

注解

在调用此方法之前，调用对等方需要使用 方法登录到对等协作基础结构 SignIn 。

访问此方法需要 的 PermissionStateUnrestricted。 此状态是在协作会话开始时创建的 Peer 。
