Identifies a switch used in an assembly, class, or member.

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


[AttributeUsageAttribute(AttributeTargets.Assembly | AttributeTargets.Class | AttributeTargets.Constructor | AttributeTargets.Method | AttributeTargets.Property | AttributeTargets.Event)]
public sealed class SwitchAttribute : Attribute

System_CAPS_pubmethodSwitchAttribute(String, Type)

Initializes a new instance of the SwitchAttribute class, specifying the name and the type of the switch.


Gets or sets the description of the switch.


Gets or sets the display name of the switch.


Gets or sets the type of the switch.


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from 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 all switch attributes for the specified assembly.


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.)

A SwitchAttribute attribute can be used on an assembly, class, constructor, method, property, or event.

The SwitchAttribute attribute can be used by tools that inspect an assembly for configuration settings.

The following example shows how to use the SwitchAttribute attribute to identify the switch used in an assembly. This code example is part of a larger example provided for the TraceSource class.

[SwitchAttribute("SourceSwitch", typeof(SourceSwitch))]
static void Main()
