In object-oriented programming, classes can contain attributes and methods. An attribute in a relational database can be represented as a column or field.. In computing, an attribute is a specification that defines a property of an object, element, or file.
A property, in some object-oriented programming languages, is a special sort of class member, intermediate in functionality between a field (or data member) and a method.The syntax for reading and writing of properties is like for fields, but property reads and writes are (usually) translated to 'getter' and 'setter' method calls.
Modern programming languages often offer the ability to generate the boilerplate for mutators and accessors in a single line—as for example C#'s public string Name { get; set; } and Ruby's attr_accessor :name. In these cases, no code blocks are created for validation, preprocessing or synthesis.
Type inference – C# 3 with implicitly typed local variables var and C# 9 target-typed new expressions new List comprehension – C# 3 LINQ; Tuples – .NET Framework 4.0 but it becomes popular when C# 7.0 introduced a new tuple type with language support [104] Nested functions – C# 7.0 [104] Pattern matching – C# 7.0 [104]
Identifier names may be prefixed by an at sign (@), but this is insignificant; @name is the same identifier as name. Microsoft has published naming conventions for identifiers in C#, which recommends the use of PascalCase for the names of types and most type members, and camelCase for variables and for private or internal fields.

SimpleHtmlDom is a simple HTML document object model in C#, which can generate HTML string programmatically. APIs that expose DOM implementations: JAXP (Java API for XML Processing) is an API for accessing DOM providers; Lazarus (Free Pascal IDE) contains two variants of the DOM - with UTF-8 and ANSI format; Inspection tools:
In this example, the variable z will have the value 42. Although this may not be what the programmer anticipated, it is a well-defined result. If y were a different string, one that could not be converted to a number (e.g. "Hello World"), the result would be well-defined as well. Note that a program can be type-safe or memory-safe and still ...
Server Side Includes (SSI) is a simple interpreted server-side scripting language used almost exclusively for the World Wide Web.It is most useful for including the contents of one or more files into a web page on a web server (see below), using its #include directive.
