  2. Value type and reference type - Wikipedia

    en.wikipedia.org/wiki/Value_type_and_reference_type

    In C#, apart from the distinction between value types and reference types, there is also a separate concept called reference variables. [3] A reference variable, once declared and bound, behaves as an alias of the original variable, but it can also be rebounded to another variable by using the reference assignment operator = ref. The variable ...

    readonly. Specify that the subsequent array address operation performs no type check at runtime, and that it returns a controlled-mutability managed pointer. Prefix to instruction 0xFE 0x1D refanytype: Push the type token stored in a typed reference. Object model instruction 0xC2 refanyval <type> Push the address stored in a typed reference.

  4. Weak reference - Wikipedia

    en.wikipedia.org/wiki/Weak_reference

    In computer programming, a weak reference is a reference that does not protect the referenced object from collection by a garbage collector, unlike a strong reference.An object referenced only by weak references – meaning "every chain of references that reaches the object includes at least one weak reference as a link" – is considered weakly reachable, and can be treated as unreachable and ...

    A generator expression may be used in Python versions >= 2.4 which gives lazy evaluation over its input, and can be used with generators to iterate over 'infinite' input such as the count generator function which returns successive integers:

  6. Anonymous type - Wikipedia

    en.wikipedia.org/wiki/Anonymous_type

    Anonymous types are a feature of C# 3.0, Visual Basic .NET 9.0, Oxygene, Scala and Go that allows data types to encapsulate a set of properties into a single object without having to first explicitly define a type. [1] This is an important feature for the SQL-like LINQ feature that is integrated into C# and VB

  7. Comparison of C Sharp and Java - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_C_Sharp_and_Java

    out, ref: C# has support for output and reference parameters. These allow returning multiple output values from a method, or passing values by reference. strictfp: Java uses strictfp to guarantee the results of floating point operations remain the same across platforms. switch: In C#, the switch statement also operates on strings and longs ...

  8. C Sharp syntax - Wikipedia

    en.wikipedia.org/wiki/C_Sharp_syntax

    C# 3.0 introduced type inference, allowing the type specifier of a variable declaration to be replaced by the keyword var, if its actual type can be statically determined from the initializer. This reduces repetition, especially for types with multiple generic type-parameters , and adheres more closely to the DRY principle.

  9. C Sharp (programming language) - Wikipedia

    en.wikipedia.org/wiki/C_Sharp_(programming_language)

    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]
