Setting up Known External Types

LINQ Reporting Engine must be aware of custom external types that you reference in your template before the engine processes the template. You can set up external types known by the engine through the ReportingEngine.KnownTypes property. The property represents an unordered set (that is, a collection of unique items) of Type objects. Every type in the set must meet requirements declared at “Working with Types”.

Note – Aliases of simple types like int, string, and others are known by the engine by default.

Consider the following example. Given an ImageUtil class declared at your application and a template accessing a static member of this class, you can use the following code to make the engine be aware of the class before processing the template.

ReportingEngine engine = new ReportingEngine();
engine.KnownTypes.Add(typeof(ImageUtil));
engine.BuildReport(...);
