C# programming is a popular and powerful language that is for creating scalable, interoperable, and robust applications.

Microsoft first used the name C# in 1988 for a variant of the C language designed for incremental compilation.[37] That project was hamiş completed, and the name was later reused.

You use lambda expressions in any code that requires instances of delegate types or expression trees. One example is the argument to the Task.

Note: Methods defined in object, such as equals and hashCode do derece get reference information due to performance reasons.

for parameters on lambda expressions. The syntax and the restrictions on default parameter values are the same bey for methods and local functions. The following example declares a lambda expression with a default parameter, then calls it once using the default and once with two explicit parameters:

Now that you've got the basics, you emanet keep learning with the self-guided C# tutorials on Microsoft Learn.

The following example produces a sequence that contains all elements in the numbers array that precede the 9, because that's the first number in the sequence that doesn't meet the condition:

While there are no strict prerequisites to learning C#, it is a high-level language. So, if you have experience in any programming language like C or C++, then it will significantly enhance your learning experience.

Different from most other languages, call-by-reference parameters have to be marked both at the function definition and at the calling şehir, and you emanet choose between ref and out, the latter allowing handing over an uninitialized variable which will have a definite value on return.[77] Additionally, you yaşama specify a variable-sized argument list by applying the params keyword to C# the last parameter.[78] Certain specific kinds of methods, such as those that simply get or kaş a field's value by returning or assigning it, do hamiş require an explicitly stated full signature, but in the general case, the definition of a class includes the full signature declaration of its methods.[79]

The above line imports all types in the System namespace. For example, the Console class used later in the source code is defined in the System namespace, meaning it sevimli be used without supplying the full name of the type (which includes the namespace).

çın kullanıldığında, soyut sınıflar kodunuzun kalitesini zaitrabilir ve ihya sürecinizi iyileştirebilir. Fakat, fuzuli yahut yanlış kullanıldığında, kodunuzun muhtelitşıklaşmasına ve bakımının zorlaşmasına illet olabilirler. Bu nedenle, soyut sınıfları rast senaryolarda ve şayan bir şekilde takmak önemlidir.

Attributes on lambda expressions are useful for code analysis, and emanet be discovered via reflection. One consequence of this decision is that the System.Diagnostics.ConditionalAttribute cannot be applied to a lambda expression.
