Invoke() vs. BeginInvoke(): When to Use Synchronous vs. Asynchronous Method Calls?

Synchronous and asynchronous method call:

and choose Invoke() BeginInvoke() The key to efficient programming is to understand the subtle difference between similar methods.

and are two common examples. This article will explore their differences and clarify their uses and advantages.

Invoke() BeginInvoke() and

: Comparison analysis

Invoke() The method is designed to perform the method on the same thread as the caller to perform operations simultaneously. This means that calling threads will be waiting before the approval method is completed. BeginInvoke() On the contrary, asynchronous operation. It is called on a separate thread (usually a thread in the thread pool). It is worth noting that returns a

object, allowing the call party to track the execution status of the call method.

Invoke()

The actual application of

and BeginInvoke() BeginInvoke() IAsyncResult

and : Invoke() BeginInvoke()

: Synchronous execution method and wait for it to complete. This method is applicable when the results need to be executed and retrieved immediately. Delegate.Invoke() Delegate.BeginInvoke() : Asynchronous execution method, allow calling threads to continue execution without waiting to be completed. This method is very favorable when the CEO runs the task for a long time and does not want to block the caller.

• Delegate.Invoke() and

  (suitable for Windows window):

• Delegate.BeginInvoke()

  : Execute the method on the GUI thread and wait for it to complete. This method is applicable when ensuring the execution of the GUI thread and the consistency of data.

: The method is executed on the GUI thread, but it does not wait for it to complete. This is very useful for updating the UI without affecting the execution of the call party. Control.Invoke() Control.BeginInvoke()

Other considerations: thread objects and

• Control.Invoke() Create a separate thread object and call it on it, which is equivalent to using

  on the commission. Both methods are allowed to perform code asynchronous on separate threads. However, is usually more popular due to its simplicity and automatic thread pool management.
• Conclusion

  Control.BeginInvoke()

  and
satisfy different use cases, and provide different methods to execute methods on individual threads. Understanding their differences enable developers to optimize code performance, avoid potential deadlocks and ensure data integrity, thereby improving the efficiency and robustness of applications.
