RemotingConfiguration.IsActivationAllowed 方法

  • 项目

返回一个布尔值，该值指示是否允许由客户端激活指定的 Type。

**命名空间:**System.Runtime.Remoting
**程序集:**mscorlib（在 mscorlib.dll 中）

语法

声明
Public Shared Function IsActivationAllowed ( _
    svrType As Type _
) As Boolean
用法
Dim svrType As Type
Dim returnValue As Boolean

returnValue = RemotingConfiguration.IsActivationAllowed(svrType)

public static bool IsActivationAllowed (
    Type svrType
)

public:
static bool IsActivationAllowed (
    Type^ svrType
)

public static boolean IsActivationAllowed (
    Type svrType
)

public static function IsActivationAllowed (
    svrType : Type
) : boolean

参数

  • svrType
    要检查的对象 Type。

返回值

如果允许由客户端激活指定的 Type，则为 true；否则为 false。

异常

异常类型 条件

SecurityException

在调用堆栈上部，至少有一个调用方没有配置远程处理类型和通道的权限。

备注

当前方法用于服务器端以确定服务器是否显式允许对象 Type 的激活。

示例

' Check whether the 'MyServerImpl' object is allowed for activation or not.
If RemotingConfiguration.IsActivationAllowed(GetType(MyServerImpl)) Then
   ' Get the registered activated service types .
   Dim myActivatedServiceEntries As ActivatedServiceTypeEntry() = _ 
                       RemotingConfiguration.GetRegisteredActivatedServiceTypes()
   Console.WriteLine("The Length of the registered activated service type array is " + _ 
                                  myActivatedServiceEntries.Length.ToString())
   Console.WriteLine("The Object type is:" + _ 
                           myActivatedServiceEntries(0).ObjectType.ToString())
End If

// Check whether the 'MyServerImpl' object is allowed for 
// activation or not.
if(RemotingConfiguration.IsActivationAllowed(typeof(MyServerImpl)))
{
 // Get the registered activated service types .
 ActivatedServiceTypeEntry[] myActivatedServiceEntries =
       RemotingConfiguration.GetRegisteredActivatedServiceTypes();
Console.WriteLine("The Length of the registered activated service"
                 +" type array is "+myActivatedServiceEntries.Length);
Console.WriteLine("The Object type is:"
                    +myActivatedServiceEntries[0].ObjectType);
}

// Check whether the 'MyServerImpl' object is allowed for 
// activation or not.
if ( RemotingConfiguration::IsActivationAllowed( MyServerImpl::typeid ) )
{
   // Get the registered activated service types .
   array<ActivatedServiceTypeEntry^>^myActivatedServiceEntries = RemotingConfiguration::GetRegisteredActivatedServiceTypes();
   Console::WriteLine( "The Length of the registered activated service type array is {0}", myActivatedServiceEntries->Length );
   Console::WriteLine( "The Object type is:{0}", myActivatedServiceEntries[ 0 ]->ObjectType );
}

// Check whether the 'MyServerImpl' object is allowed for 
// activation or not.
if (RemotingConfiguration.IsActivationAllowed(MyServerImpl.
    class.ToType())) {
    // Get the registered activated service types .
    ActivatedServiceTypeEntry myActivatedServiceEntries[] = 
        RemotingConfiguration.GetRegisteredActivatedServiceTypes();
    Console.WriteLine("The Length of the registered activated service"
        + " type array is " + myActivatedServiceEntries.get_Length());
    Console.WriteLine("The Object type is:"
        + myActivatedServiceEntries[0].get_ObjectType());
}
