C# - Dynamic Type. C# 4.0 (.NET 4.5) introduced a new type that avoids compile time type checking. You have learned about the implicitly typed variable- var in the previous section where the compiler assigns a specific type based on the value of the expression. A dynamic type escapes type checking at compile time; instead, it resolves type at run time.

Your A class should implement indexer operator (How do I overload the square-bracket operator in C#?). That operator can return Func<>, which will allow you to call it as a[key](arg). That function can return another object with indexer and so on.

C# - Indexer An Indexer is a special type of property that allows a class or structure to be accessed the same way as array for its internal collection. It is same as property except that it defined with this keyword with square bracket and parameters.

function Variable_Indexer(Self : Dynamic_Array; Indexer : Positive) return Variable_Reference is begin return Variable_Reference'(Data => Self.Backing(Index)'Access); end Variable_Indexer; Now, instead of creating a new value on the heap, and returning a pointer to that, it now returns a pointer to the element in the array; this is proper behavior.

The second line does not compile because 2.5 is typed as a double and line 3 does not compile because Math.Sqrt expects a double. Obviously, all you have to do is cast and/or change your variable type, but there may be situations where dynamic makes sense to use.

In most situations it would be inadvisable to use the dynamic type unless you are integrating with a dynamic language or another framework where types are not known at compile time. Because the compiler does not know what type the dynamic variable will eventually become, so it’s unable to offer method or property code hints in Visual Studio.

Oct 15, 2018 · Dynamic object interoperability are C# types you can use to access the DLR. These types include DynamicObject and ExpandoObject. There are more types available but pay attention to these two when working with the dynamic type. To see how the DLR and CLR fit together, review this figure: The DLR sits on top of the CLR.

A pointer is a variable that holds the 16-bit logical address of another variable, a structure, or a function. Dynamic C does not currently support long pointers. The indirection operator (*) is used to declare a variable as a pointer. The address operator (&) is used to set the pointer to the address of a variable.

Apr 06, 2010 · dynamic is a new static type that acts like a placeholder for a type not known until runtime. Once the dynamic object is declared, it is possible to call operations, get and set properties on it, even pass the dynamic instance pretty much as if it were any normal type.
