Func in C#: C# 3.0 includes built-in generic delegate types Func and Action, so that you don't need to define custom delegates as above. Func is a generic delegate included in the System namespace. It has zero or more input parameters and one out parameter. The last parameter is considered as an out parameter. For example, a Func delegate that takes one input parameter and one out parameter is defined in the System namespace as below: Func in C#: namespace System { public delegate TResult Func< in T, out TResult>(T arg); } The last parameter in the angle brackets > is considered as the return type and remaining parameters are considered as input parameter types as shown in the following figure.

Concatenation In C# Free C#.NET Course. Concatenation in C#. << Continues from previous lesson. Another thing we can do is something called Concatenation. Concatenation is joining things together. You can join direct text with variables, or join two or more variables to make a longer string. A coding example may clear things up.

- Common Intermediate Language (formerly known as MSIL, or Microsoft Intermediate Language) is a low-level assembly-type programming language using the .NET-platform. It is the language into which high-level .NET-languages such as C#, Visual Basic.NET, J# and F# are compiled. CIL is then made into an executable (.exe) which can then be run. CIL is very complex compared to, say, C#, and a single instruction in C#, like: System.Console.WriteLine(Hello, World!); ...

Difference between C++ and C# C#, also known as C sharp, is an object oriented programming language. C# is a multi-paradigm programming language. It includes strong typing, imperative, declarative, functional, procedural, generic, object-oriented (class-based), and component-oriented programming disciplines. C# is based on the C programming language. It was originally developed by Anders Hejlsberg for Microsoft for use in its .NET framework. The C# language was later approved as a standard by Ecma (ECMA-334) and ISO (ISO/IEC 23270:2006).

What is C#? They are also the most confusing part of the languages. C# removes much of the complexity and trouble caused by pointers. In C#, automatic garbage collection and type safety are an integral part of the language. If you are not familiar with the concepts of pointers, garbage collection, and type safety, don't worry. These are all explained in my book.

Methods (C# Programming Guide) A method is a code block that contains a series of statements. A program causes the statements to be executed by calling the method and specifying any required method arguments. In C#, every executed instruction is performed in the context of a method.

Difference between C++ and C# Difference between C++ and C#. C# is a distinct language from C++. C++ is designed for general object oriented programming in the days when the typical computer was a standalone machine running a command line-based user interface. C++ is a general-purpose programming language with high-level and low-level capabilities.

What is C#? As mentioned before, with C# you are limited only by your imagination. The language places no constraints on what can be done. C# can be used for projects as diverse as creating word processors, graphics, spreadsheets, and even compilers for other languages. C# Is a Language of Few Words. C# is a language that uses a limited number of words.

What is C# mostly used for? * C# is intended to be a simple, modern, general-purpose, object-oriented programming language. * The language, and implementations thereof, should provide support for software engineering principles such as strong type checking, array bounds checking, detection of attempts to use uninitialized variables, and automatic garbage collection.

C++ Functions A function declaration tells the compiler about a function's name, return type, and parameters. A function definition provides the actual body of the function. The C++ standard library provides numerous built-in functions that your program can call. For example, function strcat() to concatenate two strings, function memcpy() to copy one memory location to another location and many more functions.

The C++ 'const' Declaration: Why & How The C++ 'const' Declaration: Why & How. The 'const' system is one of the really messy features of C++. It is simple in concept: variables declared with ‘const’ added become constants and cannot be altered by the program. However it is also used to bodge in a substitute for one of the missing features of C++ and there it gets horridly complicated and sometimes frustratingly restrictive. The following attempts to explain how 'const' is used and why it exists.

C++ On the other hand, C99 introduced a number of new features that C++ did not support, were incompatible or redundant in C++, such as variable-length arrays, native complex-number types (however, the std::complex class in the C++ standard library provides similar functionality, although not code-compatible), designated initializers, compound literals, and the restrict keyword.

C++/CX C++/CX. C++/CX (component extensions) is a language extension for C++ compilers from Microsoft that enables C++ programmers to write programs for the new Windows Runtime platform, or WinRT. The language extensions borrow syntax from C++/CLI but target the Windows Runtime and native code instead of the Common Language Runtime and managed code.

- Func vs. Action vs. Predicate. The difference between Func and Action is simply whether you want the delegate to return a value (use Func) or not (use Action). Func is probably most commonly used in LINQ - for example in projections: list.Select(x => x.SomeProperty) or filtering: list.Where(x => x.SomeValue == someOtherValue) or key selection: list.Join(otherList, x => x.FirstKey, y => y.SecondKey, ...) Action is more commonly used for things like List<T>.ForEach: execute the given action for each item in ...

How to calculate a CRC in C# In many industries, the first polynomial is in use to create CRC tables and then apply it for performance purposes. The default polynomial, defined by IEEE 802.3 is 0xA001 for 16 bit and 0×04C11DB7 for 32 bit. We're in C#, thus we should use its inversed version which is 0×8408 for 16 bit and 0xEDB88320 for 32 bit. We're going to use those polynomials also in our sample. So let’s start. Because CRC is HashAlgorithm after all, we can derive our classes from System.Security.Cryptography.HashAlgorithm class.

Action and Func Delegates in C# .NET Func<>. 1  The generic Func<> delegate is used when we want to point to a method that returns a value. 2  This delegate can point to a method that takes up to 16 Parameters and returns a value. 3  Always remember that the final parameter of Func<> is always the return value of the method.
