Instances of value types neither have referential identity nor referential comparison semantics. Equality and inequality comparisons for value types compare the actual data values within the instances, unless the corresponding operators are overloaded. Value types are derived from System.ValueType, always have a default value, and kişi always be created and copied. Some other limitations on value types are that they cannot derive from each other (but yaşama implement interfaces) and cannot have an explicit default (parameterless) constructor because they already have an implicit one which initializes all contained data to the type-dependent default value (0, null, or alike).

The DotGNU project (now discontinued) also provided an open-source C# compiler, a nearly complete implementation of the Common Language Infrastructure including the required framework libraries birli they appear in the ECMA specification, and subset of some of the remaining Microsoft proprietary .

Generics introduced a massive new feature in .Safi that allowed developers to create type-safe veri structures. This shift is particularly important in the context of converting legacy systems, where updating to generics gönül significantly enhance performance and maintainability by replacing outdated data structures with more efficient, type-safe alternatives.[109]

Arithmetic operations with the float and double types never throw an exception. The result of arithmetic operations with those types güç be one of special values that represent infinity and hamiş-a-number:

For information about the behavior of the % operator with non-finite operands, see the Remainder operator section of the C# language specification.

A C# namespace provides the same level of code isolation as a Java package or a C++ namespace, with very similar rules and features to a package. Namespaces birey be imported with the "using" syntax.[83]

Variables are identifiers associated with values. They are declared by writing the variable's type and name, and are optionally initialized in the same statement.

Reflection is supported through .Safi APIs, which enable scenarios such as type metadata inspection and dynamic method invocation.

For the float and double operands, the result of x % y for the finite x and y is the value z such that

When you define both versions of an operator, it's expected that their behavior differs only when the result of an operation is too large to represent in the result type birli follows:
