Anonymous Types

• Anonymous types are class types that derive directly from object, and that cannot be cast to any type except object.
  
• The compiler provides a name for each anonymous type, although your application cannot access it.
  
• You cannot declare a field, a property, an event, or the return type of a method as having an anonymous type.
  
• You cannot declare a formal parameter of a method, property, constructor, or indexer as having an anonymous type.
  
• To pass an anonymous type, or a collection that contains anonymous type, as an argument to a method, you can declare the parameter as type object.
  
• Two instances of the same anonymous type are equal only if all their properties are equal.
  
• anonymous types typically used in the 'Select' clause of a query expression to return a subset of properties from each object in the source sequence.
  eg:- LINQ Query expression.
  var anonymousData = from pl in data select new {pl.Fname, pl.Lname};
  
• Anonymous type contain one or more public read-only properties.
  
• We can create anonymous types by using 'new' keyword together with the object initializer.
  eg:- var anonymousData = new {Fname="Vivek", Lname="Sharma"};
  
• Anonymous type is a way to define read-only properties into a single object without having to define type explicitly.
  
• Anonymous type throws compile time errors.
