Many operations in Silverlight need to be completed asynchronously, but sometimes multiple asynchronous operations need to be completed in a certain order. events are a way to convert asynchronous operations into synchronous operations.
Lambda is a concise way to operate events. When events, lambda, and synchronization are combined, the event handler cannot be removed. See the following code:
