The DebuggerDisplay attribute can be added to a class, structure or many other elements of your code. The attribute includes a single argument that is supplied as a string. This string is displayed in debugger windows instead of the object's class name or the results of the ToString method. The string can contain references to fields, properties and methods in the class so that the actual values from an object may be included in its description. It may also include simple expressions.
