NCache 4.6 - Online Documentation

Locking with Expiration

If time is specified as a value of TimeSpan, NCache would lock the item for that specified duration.
      To utilize the API, include the following namespace in your application: Alachisoft.NCache.Web.Caching.
            LockHandle lockHandle = new LockHandle();
            //Specify time span of 10 sec for which the item remains locked
            TimeSpan lockSpan = new TimeSpan(0, 0, 10);
            string key = "Product:1001";
                bool lockAcquired = cache.Lock(key, lockSpan, out lockHandle);
                //Verify that the lock is released automatically after this time period.
            catch (OperationFailedException ex)
                // handle exception
