The cast operator is not overloadable, but one can write a conversion operator method which lives in the target class. Conversion methods can define two varieties of operators, implicit and explicit conversion operators. The implicit operator will cast without specifying with the cast operator (()) and the explicit operator requires it to be used.
Cast obj to class. Object model instruction 0xFE 0x01 ceq: Push 1 (of type int32) if value1 equals value2, else push 0. Base instruction 0xFE 0x02 cgt: Push 1 (of type int32) if value1 greater than value2, else push 0. Base instruction 0xFE 0x03 cgt.un: Push 1 (of type int32) if value1 greater than value2, unsigned or unordered, else push 0.
C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.
The word cast, on the other hand, refers to explicitly changing the interpretation of the bit pattern representing a value from one type to another. For example, 32 contiguous bits may be treated as an array of 32 Booleans, a 4-byte string, an unsigned 32-bit integer or an IEEE single precision floating point value.
Generics, or parameterized types, or parametric polymorphism is a .NET 2.0 feature supported by C# and Visual Basic. Unlike C++ templates, .NET parameterized types are instantiated at runtime rather than by the compiler; hence they can be cross-language whereas C++ templates cannot.
The following examples illustrates how C++ cast operators can break type safety when used incorrectly. The first example shows how basic data types can be incorrectly cast: #include <iostream> using namespace std ; int main () { int ival = 5 ; // integer value float fval = reinterpret_cast < float &> ( ival ); // reinterpret bit pattern cout ...
C# 4.0 is a version of the C# programming language that was released on April 11, 2010. Microsoft released the 4.0 runtime and development environment Visual Studio 2010 . [ 1 ] The major focus of C# 4.0 is interoperability with partially or fully dynamically typed languages and frameworks, such as the Dynamic Language Runtime and COM .
In these languages, the typeof operator is the method for obtaining run-time type information. In other languages, such as C# [2] or D [3] and, to some degree, in C (as part of nonstandard extensions and proposed standard revisions), [4] [5] the typeof operator returns the static type of the operand. That is, it evaluates to the declared type ...
