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 the Object 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.)
	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.)

Remarks

Designer-provided types and members that are not part of the code specifically created by the user can complicate the debugging experience. This attribute suppresses the display of these adjunct types and members in the debugger window and automatically steps through, instead of into, designer-provided code. When the debugger encounters this attribute when it steps through user code, the user will not see the designer-provided code and will skip to the next user-supplied code statement.

Note:
The common language runtime attaches no semantics to this attribute. It is provided for use by source code debuggers. For example, in Visual Studio, the debugger does not display an element that has this attribute in the debugger window, does not stop in a method that has this attribute, and does not allow a breakpoint to be set in that method.

The debugger behavior when the DebuggerNonUserCodeAttribute is present is similar to using a combination of the DebuggerHiddenAttribute attribute, which hides the code from the debugger, and the DebuggerStepThroughAttribute attribute, which tells the debugger to step through, instead of into, the code it is applied to.
