ReliabilityContractAttribute ReliabilityContractAttribute ReliabilityContractAttribute ReliabilityContractAttribute Class

Definition

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

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

Examples

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

using namespace System;
using namespace System::Runtime::ConstrainedExecution;

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

Remarks

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.

Constructors

ReliabilityContractAttribute(Consistency, Cer) ReliabilityContractAttribute(Consistency, Cer) ReliabilityContractAttribute(Consistency, Cer) ReliabilityContractAttribute(Consistency, Cer)

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

Properties

Cer Cer Cer Cer

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

ConsistencyGuarantee ConsistencyGuarantee ConsistencyGuarantee ConsistencyGuarantee

Gets the value of the Consistency reliability contract.

TypeId TypeId TypeId TypeId

When implemented in a derived class, gets a unique identifier for this Attribute.
