ReliabilityContractAttribute 類別


定義某個程式碼的作者與仰賴該程式碼的開發人員之間的可靠性合約。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
public sealed class ReliabilityContractAttribute : Attribute
[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
    inherit Attribute
Public NotInheritable Class ReliabilityContractAttribute
Inherits Attribute


下列程式碼範例將示範如何使用 ReliabilityContractAttribute 屬性來記錄元件的可靠性層級。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;

   Consistency::MayCorruptInstance, Cer::None)];
namespace ReliabilityLibrary
   class SomeClass {};
using System;
using System.Runtime.ConstrainedExecution;

   Consistency.MayCorruptInstance, Cer.None)]
namespace ReliabilityLibrary
   class SomeClass {}
Imports System.Runtime.ConstrainedExecution

<assembly:ReliabilityContractAttribute( _ 
   Consistency.MayCorruptInstance, Cer.None)> 
Namespace ReliabilityLibrary
   Class SomeClass
   End Class
End Namespace


ReliabilityContractAttribute 屬性提供一種機制,可讓您記載程式碼,並指出您可以在可能導致不一致狀態的例外狀況中,進行哪些類型的可靠性保證。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. 在此情況下,例外狀況會定義為可由 common language runtime 在執行時間產生的非同步例外狀況,例如中止的執行緒、記憶體不足的情況,以及堆疊溢位。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. 您可以將 ReliabilityContractAttribute 屬性套用至元件、類型和方法。You can apply the ReliabilityContractAttribute attribute to assemblies, types, and methods.

使用此屬性搭配 Consistency 列舉,藉由記錄特定程式碼片段中的可靠性層級來定義可靠性合約。Use this attribute with the Consistency enumeration to define a reliability contract by documenting the level of reliability in a particular piece of code.


ReliabilityContractAttribute(Consistency, Cer)

使用指定的 ReliabilityContractAttribute 保證和 Consistency 值,初始化 Cer 類別的新執行個體。Initializes a new instance of the ReliabilityContractAttribute class with the specified Consistency guarantee and Cer value.



取得值,該值決定方法、類型或組件在限制執行區域 (CER) 下被呼叫時的行為。Gets the value that determines the behavior of a method, type, or assembly when called under a Constrained Execution Region (CER).


取得 Consistency 可靠性合約的值。Gets the value of the Consistency reliability contract.


在衍生類別中實作時,取得這個 Attribute 的唯一識別碼。When implemented in a derived class, gets a unique identifier for this Attribute.

傳回值,這個值指出此執行個體是否與指定的物件相等。Returns a value that indicates whether this instance is equal to a specified object.

(繼承來源 Attribute)

傳回這個執行個體的雜湊碼。Returns the hash code for this instance.

(繼承來源 Attribute)

取得目前執行個體的 TypeGets the Type of the current instance.

(繼承來源 Object)

在衍生類別中覆寫時,表示這個執行個體的值是衍生類別的預設值。When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

(繼承來源 Attribute)

在衍生類別中覆寫時,會傳回值,表示這個執行個體是否等於指定物件。When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

(繼承來源 Attribute)

建立目前 Object 的淺層複製。Creates a shallow copy of the current Object.

(繼承來源 Object)

傳回代表目前物件的字串。Returns a string that represents the current object.

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

將一組名稱對應至一組對應的分派識別項 (Dispatch Identifier)。Maps a set of names to a corresponding set of dispatch identifiers.

(繼承來源 Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

擷取物件的類型資訊,可以用來取得介面的類型資訊。Retrieves the type information for an object, which can be used to get the type information for an interface.

(繼承來源 Attribute)

擷取物件提供的類型資訊介面數目 (0 或 1)。Retrieves the number of type information interfaces that an object provides (either 0 or 1).

(繼承來源 Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

提供物件所公開的屬性和方法的存取權。Provides access to properties and methods exposed by an object.
