ContractVerificationAttribute Class


Instructs analysis tools to assume the correctness of an assembly, type, or member without performing static verification.

public ref class ContractVerificationAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Assembly | System.AttributeTargets.Class | System.AttributeTargets.Constructor | System.AttributeTargets.Method | System.AttributeTargets.Property | System.AttributeTargets.Struct)]
public sealed class ContractVerificationAttribute : Attribute
type ContractVerificationAttribute = class
    inherit Attribute
Public NotInheritable Class ContractVerificationAttribute
Inherits Attribute


Use ContractVerification(false) to explicitly mark an assembly, type, or member as not requiring verification. The most specific element found (member, type, and then assembly) takes precedence. Applying this attribute to a property, type, or assembly has the following effects:

  • When you apply it to a property, it applies to both the get accessor and the set accessor.

  • When you apply it to a type, it applies to all members of the type, including nested types.

  • When you apply it to an assembly, it applies to all types and members of the assembly.



Initializes a new instance of the ContractVerificationAttribute class.



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

(Inherited from Attribute)

Gets the value that indicates whether to verify the contract of the target.



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)

Creates a shallow copy of the current Object.

(Inherited from Object)

Returns a string that represents the current object.

Explicit Interface Implementations

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

Maps a set of names to a corresponding set of dispatch identifiers.

(Inherited from Attribute)
_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)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.
