Calling Async Methods from Main()
One of the new features introduced in C# is support for asynchronous programming. This allows you to perform long-running operations without blocking the main thread, which can lead to a more responsive user interface.
In the provided code sample, you have an async method called Go() that you want to call from the Main() method. To do this, you can use one of two approaches:
Option 1: Using async/await (C# 7.1 and newer)
In C# 7.1 and newer, you can use the async keyword to make your Main() method asynchronous. This allows you to await the result of the Go() method without blocking the main thread.
static async Task Main(string[] args) { test t = new test(); await t.Go(); Console.WriteLine("finished"); Console.ReadKey(); }
Option 2: Using Blocking (for C# versions prior to 7.1)
For versions of C# prior to 7.1, you can use the Wait() method to block the main thread until the Go() method has completed.
static void Main(string[] args) { test t = new test(); t.Go().Wait(); Console.WriteLine("finished"); Console.ReadKey(); }
The approach you used in your code sample, involving a callback, is not necessary. Using either the async/await pattern or the Wait() method will allow you to call async methods from Main() in a straightforward manner.
The above is the detailed content of How Can I Call Asynchronous Methods from the Main() Method in C#?. For more information, please follow other related articles on the PHP Chinese website!

Mastering polymorphisms in C can significantly improve code flexibility and maintainability. 1) Polymorphism allows different types of objects to be treated as objects of the same base type. 2) Implement runtime polymorphism through inheritance and virtual functions. 3) Polymorphism supports code extension without modifying existing classes. 4) Using CRTP to implement compile-time polymorphism can improve performance. 5) Smart pointers help resource management. 6) The base class should have a virtual destructor. 7) Performance optimization requires code analysis first.

Integrating XML in a C project can be achieved through the following steps: 1) parse and generate XML files using pugixml or TinyXML library, 2) select DOM or SAX methods for parsing, 3) handle nested nodes and multi-level properties, 4) optimize performance using debugging techniques and best practices.

XML is used in C because it provides a convenient way to structure data, especially in configuration files, data storage and network communications. 1) Select the appropriate library, such as TinyXML, pugixml, RapidXML, and decide according to project needs. 2) Understand two ways of XML parsing and generation: DOM is suitable for frequent access and modification, and SAX is suitable for large files or streaming data. 3) When optimizing performance, TinyXML is suitable for small files, pugixml performs well in memory and speed, and RapidXML is excellent in processing large files.

The main differences between C# and C are memory management, polymorphism implementation and performance optimization. 1) C# uses a garbage collector to automatically manage memory, while C needs to be managed manually. 2) C# realizes polymorphism through interfaces and virtual methods, and C uses virtual functions and pure virtual functions. 3) The performance optimization of C# depends on structure and parallel programming, while C is implemented through inline functions and multithreading.

The DOM and SAX methods can be used to parse XML data in C. 1) DOM parsing loads XML into memory, suitable for small files, but may take up a lot of memory. 2) SAX parsing is event-driven and is suitable for large files, but cannot be accessed randomly. Choosing the right method and optimizing the code can improve efficiency.

C is widely used in the fields of game development, embedded systems, financial transactions and scientific computing, due to its high performance and flexibility. 1) In game development, C is used for efficient graphics rendering and real-time computing. 2) In embedded systems, C's memory management and hardware control capabilities make it the first choice. 3) In the field of financial transactions, C's high performance meets the needs of real-time computing. 4) In scientific computing, C's efficient algorithm implementation and data processing capabilities are fully reflected.
