How to Write a Visualizer in C#

Posted by Anuraj on Wednesday, May 28, 2014

.Net Visual Studio Windows Forms

Visualizers are components of the Visual Studio debugger user interface. A visualizer creates a dialog box or another interface to display a variable or object in a manner that is appropriate to its data type. For example, an HTML visualizer interprets an HTML string and displays the result as it would appear in a browser window; a bitmap visualizer interprets a bitmap structure and displays the graphic it represents. Some visualizers enable you to modify as well as view the data. The Visual Studio debugger includes five standard visualizers. These are the text, HTML, and XML visualizers, all of which work on string objects; the WPF Tree visualizer, for displaying the properties of a WPF object visual tree; and the dataset visualizer, which works for DataSet, DataView, and DataTable objects. Visualizers are represented in the debugger by a magnifying glass icon. When you see the magnifying glass icon in a DataTip, in a debugger variables window, or in the QuickWatch dialog box, you can click the magnifying glass to select a visualizer appropriate to the data type of the corresponding object. Visualizers are not supported on the Compact Framework.
