public static bool IsOneWay(System.Reflection.MethodBase method);
[System.Security.SecurityCritical]
public static bool IsOneWay(System.Reflection.MethodBase method);
static member IsOneWay : System.Reflection.MethodBase -> bool
[<System.Security.SecurityCritical>]
static member IsOneWay : System.Reflection.MethodBase -> bool
Public Shared Function IsOneWay (method As MethodBase) As Boolean

參數

範例

public ref class HelloServer: public MarshalByRefObject
{
public:
   HelloServer()
   {
      Console::WriteLine( "HelloServer activated." );
   }

   [OneWay]
   void SayHelloToServer( String^ name )
   {
      Console::WriteLine( "Client invoked SayHelloToServer(\" {0}\").", name );
   }

   // IsOneWay: Note the lack of the OneWayAttribute adornment on this method.
   [SecurityPermissionAttribute(SecurityAction::Demand, Flags=SecurityPermissionFlag::Infrastructure)]   
   String^ SayHelloToServerAndWait( String^ name )
   {
      Console::WriteLine( "Client invoked SayHelloToServerAndWait(\" {0}\").", name );
      Console::WriteLine( "Client waiting for return? {0}", RemotingServices::IsOneWay( MethodBase::GetCurrentMethod() ) ? (String^)"No" : "Yes" );
      return String::Format( "Hi there, {0}.", name );
   }
};

public class HelloServer : MarshalByRefObject {

   public HelloServer() {
      Console.WriteLine("HelloServer activated.");
   }

   [OneWay()]
   public void SayHelloToServer(string name) {
      Console.WriteLine("Client invoked SayHelloToServer(\"{0}\").", name);
   }   

   // IsOneWay
   // Note the lack of the OneWayAttribute adornment on this method.
   public string SayHelloToServerAndWait(string name) {
      Console.WriteLine("Client invoked SayHelloToServerAndWait(\"{0}\").", name);

      Console.WriteLine(
         "Client waiting for return? {0}",
         RemotingServices.IsOneWay(MethodBase.GetCurrentMethod()) ? "No" : "Yes"
      );

      return "Hi there, " + name + ".";
   }
}

Public Class HelloServer
    Inherits MarshalByRefObject

    Shared Sub New()
        Console.WriteLine("HelloServer activated.")
    End Sub

    <OneWay()> Public Sub SayHelloToServer(ByVal name As String)
        Console.WriteLine("Client invoked SayHelloToServer(""{0}"").", name)
    End Sub

    'IsOneWay

    Public Function SayHelloToServerAndWait(ByVal name As String) As String

        Console.WriteLine( _

            IIf(RemotingServices.IsOneWay(MethodBase.GetCurrentMethod()), "No", "Yes") _
        )

        Return "Hi there, " + name + "."
    End Function

End Class

備註

當呼叫單向方法時，用戶端不會等待伺服器完成訊息處理。 用戶端方法回傳給應用程式時，完全不知道伺服器是否能成功處理該訊息。 方法 會用 OneWayAttribute標記為單向。

單向方法不能有返回值或任何出函參數。
