[AttributeUsageAttribute(AttributeTargets::Property | AttributeTargets::Field, 
	AllowMultiple = false)]
public ref class DebuggerBrowsableAttribute sealed : Attribute


Initializes a new instance of the DebuggerBrowsableAttribute class.


Gets the display state for the attribute.

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.)


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.)


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

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute::GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

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

System_CAPS_pubinterfaceSystem_CAPS_privmethod_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.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute::Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)


In .NET Framework version 2.0, the DebuggerBrowsableAttribute class is not supported by Visual Basic. Using C#, you can add expansions for custom data using the DebuggerTypeProxyAttribute, DebuggerDisplayAttribute, and DebuggerBrowsableAttribute. Visual Basic supports the DebuggerDisplayAttribute attribute but not the DebuggerBrowsableAttribute attribute.

This attribute can be applied only as a single instance to properties and fields. It cannot be applied to assemblies.

The constructor for this attribute takes one of the DebuggerBrowsableState enumeration values, which specifies one of the following states:

  • Never indicates that the member is not displayed in the data window. For example, using this value for the DebuggerBrowsableAttribute on a field removes the field from the hierarchy; the field is not displayed when you expand the enclosing type by clicking the plus sign (+) for the type instance.

  • Collapsed indicates that the member is displayed but not expanded by default. This is the default behavior.

  • RootHidden indicates that the member itself is not shown, but its constituent objects are displayed if it is an array or collection.

For an example of the use of this attribute and the DebuggerDisplayAttribute and DebuggerTypeProxyAttribute attributes, see the example provided for the DebuggerDisplayAttribute class.
