DebuggableAttribute Class

Modifies code generation for runtime just-in-time (JIT) debugging. This class cannot be inherited.

Inheritance Hierarchy

System.Attribute
System.Diagnostics.DebuggableAttribute

Namespace: System.Diagnostics
Assembly: mscorlib (in mscorlib.dll)

Syntax

Visual Basic

<ComVisibleAttribute(True)> _
<AttributeUsageAttribute(AttributeTargets.Assembly Or AttributeTargets.Module, AllowMultiple := False)> _
Public NotInheritable Class DebuggableAttribute _
	Inherits Attribute

[ComVisibleAttribute(true)]
[AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Module, AllowMultiple = false)]
public sealed class DebuggableAttribute : Attribute

Visual C++

[ComVisibleAttribute(true)]
[AttributeUsageAttribute(AttributeTargets::Assembly|AttributeTargets::Module, AllowMultiple = false)]
public ref class DebuggableAttribute sealed : public Attribute

[<Sealed>]
[<ComVisibleAttribute(true)>]
[<AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Module, AllowMultiple = false)>]
type DebuggableAttribute =  
    class
        inherit Attribute
    end

The DebuggableAttribute type exposes the following members.

Constructors

	Name	Description
	DebuggableAttribute(DebuggableAttribute.DebuggingModes)	Initializes a new instance of the DebuggableAttribute class, using the specified debugging modes for the just-in-time (JIT) compiler.
	DebuggableAttribute(Boolean, Boolean)	Initializes a new instance of the DebuggableAttribute class, using the specified tracking and optimization options for the just-in-time (JIT) compiler.

Properties

	Name	Description
	DebuggingFlags	Gets the debugging modes for the attribute.
	IsJITOptimizerDisabled	Gets a value that indicates whether the runtime optimizer is disabled.
	IsJITTrackingEnabled	Gets a value that indicates whether the runtime will track information during code generation for the debugger.
	TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)

Methods

	Name	Description
	Equals	Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Returns the hash code for this instance. (Inherited from Attribute.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	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.)
	Match	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Explicit Interface Implementations

	Name	Description
	_Attribute.GetIDsOfNames	Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
	_Attribute.GetTypeInfo	Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
	_Attribute.GetTypeInfoCount	Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
	_Attribute.Invoke	Provides access to properties and methods exposed by an object. (Inherited from Attribute.)

Remarks

The DebuggableAttribute controls how the runtime treats code within the module. The runtime might track extra information about generated code, and it might disable certain optimizations based on the values contained within this attribute.

A debugger might choose to ignore the DebuggableAttribute settings when loading an assembly. However, attaching a debugger to a running program may prevent the debugger from changing the settings because they have already been applied.

To use the DebuggableAttribute with dynamic assemblies using the Reflection Emit DefineDynamicModule methods, emit the DebuggableAttribute before calling the DefineDynamicModule methods to ensure that the settings are applied to the entire assembly.
