A sequence can be filtered using LINQ's OfType method according to the types of each of its components. A new sequence that only contains elements that can be cast to the provided type is returned by the OfType method, which filters a sequence to include only those components.   Here's an illustration of how you can filter a list of object elements using the OfType function to only keep those that can be converted to the string type:  object[] objects = new object[] { 1, "string1", 2, "string2"};
var strings = objects.OfType();  Only the components that can be cast to the string type are maintained in the new sequence when the OfType function is used on the objects array in this example. "string1" and "string2" items can be found in the resulting sequence.   This technique can be used to filter collections of components so that you only see components of a particular type. For instance, if you have a list of game objects in a game engine, you can filter only the game objects that have a particular tag or component type.   In conclusion, the OfType method in LINQ may be used to filter a sequence based on the types of its elements. It filters a sequence to only include elements that can be cast to the provided type and produce a new series that contains those elements. It may be used in many different situations, such as gaming engines, where you need to filter game objects with a given tag or a specific sort of component. It is handy when you want to filter a collection of components based on their type.
