System.Runtime.CompilerServices Namespace
Visual Studio 2008
Updated: February 2009
The System.Runtime.CompilerServices namespace provides functionality for compiler writers who use managed code to specify attributes in metadata that affect the run-time behavior of the common language runtime.
This namespace is primarily for compiler writers, although several of its classes, such as InternalsVisibleToAttribute, are used in a wide variety of applications.
| Class | Description | |
|---|---|---|
![]() | AccessedThroughPropertyAttribute | Specifies the name of the property that accesses the attributed field. |
![]() | CallConvCdecl | Indicates that a method should use the Cdecl calling convention. |
![]() | CallConvFastcall | This calling convention is not supported in this version of the .NET Framework. |
![]() | CallConvStdcall | Indicates that a method should use the StdCall calling convention. |
![]() | CallConvThiscall | Indicates that a method should use the ThisCall calling convention. |
![]() | CompilationRelaxationsAttribute | Controls the strictness of the code generated by the common language runtime's just-in-time (JIT) compiler. |
![]() | CompilerGeneratedAttribute | Distinguishes a compiler-generated element from a user-generated element. This class cannot be inherited. |
![]() | CompilerGlobalScopeAttribute | Indicates that a class should be treated as if it has global scope. |
![]() | CompilerMarshalOverride | Indicates that the modified instance of a variable differs from its true type when marshaling. This class cannot be inherited. |
![]() | CustomConstantAttribute | Defines a constant value that a compiler can persist for a field or method parameter. |
![]() | DateTimeConstantAttribute | Persists an 8-byte DateTime constant for a field or parameter. |
![]() | DecimalConstantAttribute | Stores the value of a System::Decimal constant in metadata. This class cannot be inherited. |
![]() | DefaultDependencyAttribute | Provides a hint to the common language runtime (CLR) indicating how likely a dependency is to be loaded. This class is used in a dependent assembly to indicate what hint should be used when the parent does not specify the DependencyAttribute attribute. This class cannot be inherited. |
![]() | DependencyAttribute | Indicates when a dependency is to be loaded by the referring assembly. This class cannot be inherited. |
![]() | DiscardableAttribute | Marks a type definition as discardable. |
![]() | ExecutionScope | Infrastructure. Represents the runtime state of a dynamically generated method. |
![]() | ExtensionAttribute | Indicates that a method is an extension method, or that a class or assembly contains extension methods. |
![]() | FixedAddressValueTypeAttribute | Fixes the address of a static value type field throughout its lifetime. This class cannot be inherited. |
![]() | FixedBufferAttribute | Indicates that a field should be treated as containing a fixed number of elements of the specified primitive type. This class cannot be inherited. |
![]() | HasCopySemanticsAttribute | This class is not used in the .NET Framework version 2.0 and is reserved for future use. This class cannot be inherited. |
![]() | IDispatchConstantAttribute | Indicates that the default value for the attributed field or parameter is an instance of DispatchWrapper, where the WrappedObject is nullptr. |
![]() | IndexerNameAttribute | Indicates the name by which an indexer is known in programming languages that do not support indexers directly. |
![]() | InternalsVisibleToAttribute | Specifies that types that are ordinarily visible only within the current assembly are visible to another assembly. |
![]() | IsBoxed | Indicates that the modified reference type is a boxed value type. This class cannot be inherited. |
![]() | IsByValue | Indicates that a modified method argument should be interpreted as having object passed-by-value semantics. This modifier is applied to reference types. This class cannot be inherited. |
![]() | IsConst | Indicates that the modified type has a const modifier. This class cannot be inherited. |
![]() | IsCopyConstructed | Indicates that any copying of values of this type must use the copy constructor provided by the type. This class cannot be inherited. |
![]() | IsExplicitlyDereferenced | Indicates that a managed pointer represents a pointer parameter within a method signature. This class cannot be inherited. |
![]() | IsImplicitlyDereferenced | Indicates that the modified garbage collection reference represents a reference parameter within a method signature. This class cannot be inherited. |
![]() | IsJitIntrinsic | Indicates that a modified method is an intrinsic value for which the just-in-time (JIT) compiler can perform special code generation. This class cannot be inherited. |
![]() | IsLong | Indicates that a modified integer is a standard C++ long value. This class cannot be inherited. |
![]() | IsPinned | Indicates that a modified instance is pinned in memory. This class cannot be inherited. |
![]() | IsSignUnspecifiedByte | Indicates that a modifier is neither signed nor unsigned. This class cannot be inherited. |
![]() | IsUdtReturn | Indicates that a return type is a user-defined type. This class cannot be inherited. |
![]() | IsVolatile | Marks a field as volatile. This class cannot be inherited. |
![]() | IUnknownConstantAttribute | Indicates that the default value for the attributed field or parameter is an instance of UnknownWrapper, where the WrappedObject is nullptr. This class cannot be inherited. |
![]() | MethodImplAttribute | Specifies the details of how a method is implemented. This class cannot be inherited. |
![]() | NativeCppClassAttribute | Applies metadata to an assembly that indicates that a type is an unmanaged type. This class cannot be inherited. |
![]() | RequiredAttributeAttribute | Specifies that an importing compiler must fully understand the semantics of a type definition, or refuse to use it. This class cannot be inherited. |
![]() | RuntimeCompatibilityAttribute | Specifies whether to wrap exceptions that do not derive from the Exception class with a RuntimeWrappedException object. This class cannot be inherited. |
![]() | RuntimeHelpers | Provides a set of static methods and properties that provide support for compilers. This class cannot be inherited. |
![]() | RuntimeWrappedException | Wraps an exception that does not derive from the Exception class. This class cannot be inherited. |
![]() | ScopelessEnumAttribute | Indicates that a native enumeration is not qualified by the enumeration type name. This class cannot be inherited. |
![]() | SpecialNameAttribute | Indicates that a type or member is treated in a special way by the runtime or tools. This class cannot be inherited. |
![]() | StringFreezingAttribute | Deprecated. Freezes a string literal when creating native images using the Native Image Generator (Ngen.exe). This class cannot be inherited. |
![]() | StrongBox<T> | Infrastructure. Holds a reference to a value. |
![]() | SuppressIldasmAttribute | Prevents the MSIL Disassembler (Ildasm.exe) from disassembling an assembly. This class cannot be inherited. |
![]() | TypeForwardedToAttribute | Specifies a destination Type in another assembly. This class cannot be inherited. |
![]() | UnsafeValueTypeAttribute | Specifies that a type contains an unmanaged array that might potentially overflow. This class cannot be inherited. |
| Interface | Description | |
|---|---|---|
![]() | IStrongBox | Infrastructure. Defines a property for accessing the value that an object references. |
| Delegate | Description | |
|---|---|---|
![]() | RuntimeHelpers::CleanupCode | Represents a method to run when an exception occurs. |
![]() | RuntimeHelpers::TryCode | Represents a delegate to code that should be run in a try block.. |
| Enumeration | Description | |
|---|---|---|
![]() | CompilationRelaxations | Specifies parameters that control the strictness of the code generated by the common language runtime's just-in-time (JIT) compiler. |
![]() | LoadHint | Specifies the preferred default binding for a dependent assembly. |
![]() | MethodCodeType | Defines how a method is implemented. |
![]() | MethodImplOptions | Defines the details of how a method is implemented. |
