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

NameDescription
System_CAPS_pubmethod ReliabilityContractAttribute

Initializes a new instance of the ReliabilityContractAttribute class with the specified Consistency guarantee and Cer value.

NameDescription
System_CAPS_pubproperty

Gets the value that determines the behavior of a method, type, or assembly when called under a Constrained Execution Region (CER).

System_CAPS_pubproperty

Gets the value of the Consistency reliability contract.

System_CAPS_pubproperty

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

NameDescription
System_CAPS_pubmethod Equals

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.)

System_CAPS_pubmethod GetHashCode

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

System_CAPS_pubmethod GetType

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

System_CAPS_pubmethod IsDefaultAttribute

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

System_CAPS_pubmethod Match

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

System_CAPS_pubmethod ToString

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

NameDescription
System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetIDsOfNames

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

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfo

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

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfoCount

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

System_CAPS_pubinterface System_CAPS_privmethod _AttributeInvoke

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;

[assembly:ReliabilityContractAttribute(
   Consistency.MayCorruptInstance, Cer.None)]
namespace ReliabilityLibrary
{
   class SomeClass {}
}
Imports System
Imports System.Runtime.ConstrainedExecution

<assembly:ReliabilityContractAttribute( _ 
   Consistency.MayCorruptInstance, Cer.None)> 
Namespace ReliabilityLibrary
   Class SomeClass
   End Class
End Namespace
using namespace System;
using namespace System::Runtime::ConstrainedExecution;

[assembly:ReliabilityContractAttribute(
   Consistency::MayCorruptInstance, Cer::None)];
namespace ReliabilityLibrary
{
   class SomeClass {};
}
