LifetimeServices.RenewOnCallTime 属性

定义

命名空间:

System.Runtime.Remoting.Lifetime

程序集:

mscorlib.dll

获取或设置每当调用到达服务器对象时延续租约的时间。

public:
 static property TimeSpan RenewOnCallTime { TimeSpan get(); void set(TimeSpan value); };

public static TimeSpan RenewOnCallTime { get; set; }

public static TimeSpan RenewOnCallTime { get; [System.Security.SecurityCritical] set; }

member this.RenewOnCallTime : TimeSpan with get, set

[<set: System.Security.SecurityCritical>]
member this.RenewOnCallTime : TimeSpan with get, set

Public Shared Property RenewOnCallTime As TimeSpan

属性值

TimeSpan

每次调用后延续当前 TimeSpan 中的生存期租约的 AppDomain。

属性

SecurityCriticalAttribute

例外

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。 仅在设置该属性值时才会引发此异常。

示例

// Register the channel.
TcpChannel^ myChannel = gcnew TcpChannel;
ChannelServices::RegisterChannel( myChannel );
RemotingConfiguration::RegisterActivatedClientType( HelloService::typeid, "Tcp://localhost:8085" );
TimeSpan myTimeSpan = TimeSpan::FromMinutes( 10 );

// Create a remote object.
HelloService ^ myService = gcnew HelloService;
ILease^ myLease;
myLease = dynamic_cast<ILease^>(RemotingServices::GetLifetimeService( myService ));
if ( myLease == nullptr )
{
   Console::WriteLine( "Cannot lease." );
   return  -1;
}

Console::WriteLine( "Initial lease time is {0}", myLease->InitialLeaseTime );
Console::WriteLine( "Current lease time is {0}", myLease->CurrentLeaseTime );

注解

延长生存期租约的默认续订时间为 2 分钟。
