How to set the leaseTimeout setting programmaticaly?

问题

We have a WCF service (NetTcpBinding) that sits behind a load balancer. I've read that in order to avoid "stickyniss" I have lower the LeaseTime the channels get in the channel pool.

I've only found samples how to set this value using the config file, but I would like to set it programmaticaly, any pointers?

回答1:

You can access the LeaseTimeout property via the TcpTransportBindingElement, through the ConnectionPoolSettings property:

TcpTransportBindingElement tcpBE = new TcpTransportBindingElement();
tcpBE.ConnectionPoolSettings.LeaseTimeout = TimeSpan.FromSeconds(1);

If you have a NetTcpBinding object, you'll need to first convert it into a CustomBinding, then access the binding element. The example below shows one way of doing this.

NetTcpBinding myOriginalBinding = CreateBinding();
CustomBinding newBinding = new CustomBinding(myOriginalBinding);
TcpTransportBindingElement tcpBE = newBinding.Elements.Find<TcpTransportBindingElement>();
tcpBE.ConnectionPoolSettings.LeaseTimeout = TimeSpan.FromSeconds(1);
