The programming language C# version 3.0 was released on 19 November 2007 as part of .NET Framework 3.5.It includes new features inspired by functional programming languages such as Haskell and ML, and is driven largely by the introduction of the Language Integrated Query (LINQ) pattern to the Common Language Runtime.

Runtime exception handling method in C# is inherited from Java and C++. The base class library has a class called System. Exception from which all other exception classes are derived. An Exception-object contains all the information about a
In the Java virtual machine, internal type signatures are used to identify methods and classes at the level of the virtual machine code. Example: The method String String. substring (int, int) is represented in bytecode as Ljava / lang / String. substring (II) Ljava / lang / String;. The signature of the main method looks like this: [2]
Like with fields, there can be class and instance properties. The underlying methods can be virtual or abstract like any other method. [82] Since C# 3.0 the syntactic sugar of auto-implemented properties is available, [86] where the accessor (getter) and mutator (setter) encapsulate operations on a single field of a class.
For example, when scanning the list looking for a node with a given value x, setting the sentinel's data field to x makes it unnecessary to test for end-of-list inside the loop. Another example is the merging two sorted lists: if their sentinels have data fields set to +∞, the choice of the next output node does not need special handling for ...
A method is a behavior of an object parametrized by a user. Data is represented as properties of the object, and behaviors are represented as methods. For example, a Window object could have methods such as open and close, while its state (whether it is open or closed at any given point in time) would be a property.
The Contains operator checks, if the collection contains a given element. Count The Count operator counts the number of elements in the given collection. An overload taking a predicate, counts the number of elements matching the predicate. The standard query operator API also specifies certain operators that convert a collection into another ...
Much finer control of access rights can be defined using mutators and accessors. For example, a parameter may be made read-only simply by defining an accessor but not a mutator. The visibility of the two methods may be different; it is often useful for the accessor to be public while the mutator remains protected, package-private or internal.
