ReliabilityContractAttribute Class

ReliabilityContractAttribute Class


Defines a contract for reliability between the author of some code, and the developers who have a dependency on that code.

Namespace:   System.Runtime.ConstrainedExecution
Assembly:  mscorlib (in mscorlib.dll)


[AttributeUsageAttribute(AttributeTargets.Assembly | AttributeTargets.Class | AttributeTargets.Struct | AttributeTargets.Constructor | AttributeTargets.Method | AttributeTargets.Interface, 
	Inherited = false)]
public sealed class ReliabilityContractAttribute : Attribute



Gets the value of the Consistency reliability contract.


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)


This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)


Returns the hash code for this instance.(Inherited from Attribute.)


Gets the Type of the current instance.(Inherited from Object.)


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

The ReliabilityContractAttribute attribute provides a mechanism for you to document your code, and to indicate what type of reliability guarantees you can make in the face of exceptional conditions that could potentially lead to an inconsistent state. In this context, exceptional conditions are defined as asynchronous exceptions that can be generated at run time by the common language runtime, such as aborted threads, out-of-memory situations, and stack overflows. You can apply the ReliabilityContractAttribute attribute to assemblies, types, and methods.

Use this attribute with the Consistency enumeration to define a reliability contract by documenting the level of reliability in a particular piece of code.

The following code example demonstrates the use of the ReliabilityContractAttribute attribute to document the level of reliability of an assembly.

using System;
using System.Runtime.ConstrainedExecution;
