public uint PingTimeout ;

説明

Defines the duration in milliseconds between keep-alive packets, also known as pings. Default value = 500.

The ping frequency should be long enough to accumulate good statistics and short enough to compare with DisconnectTimeout. A good guideline is to have more than 3 pings per disconnect timeout, and more than 5 messages per ping. For example, with a DisconnectTimeout of 2000ms, a PingTimeout of 500ms works well.

ConnectionConfig myConfig = new ConnectionConfig();
myConfig.AddChannel(QosType.Unreliable);
myConfig.AddChannel(QosType.UnreliableFragmented);
myConfig.PingTimeout = 500;
