Using DynamicObject and ExpandoObject

C# is primarily a statically typed language. That means the compiler needs to know in advance about the data type of a variable. In the absence of this information, the compiler will throw a compilation error and will refuse to compile the code. In spite of the advantages offered by the statically typed languages, dynamic languages have their own place in application development. For example, most of the web sites developed today make use of JavaScript in some way or the other. Languages such as Python and Ruby are also popular amongst developers. The C# language now supports dynamic features through Dynamic Language Runtime (DLR). Part of these features include dynamic types, DynamicObject Class and ExpandoObject Class. This article explains these features and provides examples illustrating how these features are used.
