What are dynamic data types in C#?

Store any type of value in the dynamic data type variable. Type checking for these types of variables takes place at run-time.

The following is the syntax for declaring a dynamic type −

dynamic <variable_name> = value;

The following is an example −

dynamic val1 = 100;
dynamic val2 = 5;
dynamic val3 = 20;

The dynamic types are similar to object types except that type checking for object type variables takes place at compile time, whereas that for the dynamic type variables takes place at run time.
