C# Dynamic Type: Var vs dynamic keywords in C#

The dynamic keyword is used to define dynamic types. Dynamic type is used to avoid compile-time type checking. The compiler does not type-check dynamic type variables at compile time, instead, the compiler check the type at the run time. If the syntax of the statement is invalid, an error will be thrown at runtime.

Dynamic types are similar to object types, despite the fact that type checking for object type variables occurs at compile time rather than at runtime for dynamic type variables.
