This is a feature of C# 9.0. Similar to in scripting languages, top-level statements removes the ceremony of having to declare the Program class with a Main method. Instead, statements can be written directly in one specific file, and that file will be the entry point of the program. Code in other files will still have to be defined in classes.
When implementing multiple interfaces that contain a method with the same name and taking parameters of the same type in the same order (i.e. the same signature), similar to Java, C# allows both a single method to cover all interfaces and if necessary specific methods for each interface. C# also offers function overloading (a.k.a. ad-hoc ...
A statement terminator defines the end of an individual statement. Languages that interpret the end of line to be the end of a statement are called "line-oriented" languages. "Line continuation" is a convention in line-oriented languages where the newline character could potentially be misinterpreted as a statement terminator.
An extension method must be defined in a static class. An extension method must be defined as a static method. An extension method's first parameter must take the following form, where type is the name of the type to be extended: this type parameterName; An extension method may optionally define other parameters to follow the this parameter.
In the definition, the modifier 'this' before the first argument specifies that it's an extension method (in this case to the type 'string'). In a call, the first argument is not 'passed in' because it is already known as the 'calling' object (the object before the dot).
And in the disassembled bytecode, it takes the form of Lsome / package / Main / main:([Ljava / lang / String;) V. The method signature for the main() method contains three modifiers: public indicates that the main method can be called by any object. static indicates that the main method is a class method. void indicates that the main method has ...
In computer science, syntactic sugar is syntax within a programming language that is designed to make things easier to read or to express. It makes the language "sweeter" for human use: things can be expressed more clearly, more concisely, or in an alternative style that some may prefer.
Platform Invocation Services, commonly referred to as P/Invoke, is a feature of Common Language Infrastructure implementations, like Microsoft's Common Language Runtime, that enables managed code to call native code. Managed code, such as C# or VB.NET, provides native access to classes, methods, and types defined within the libraries that make ...
