Dynamic Data Type in C# | C# Bangla Tutorial | Advanced C#

Dynamic Type

C# 4.0 (.NET 4.5) introduced a new type that avoids compile time type checking. Dynamic Type means that you can store any type of value in the dynamic data type variable because type checking for dynamic types of variables takes place at run-time.

Dynamic Type Syntax

dynamic type can be defined using the dynamic keyword. A dynamic type changes its type at runtime based on the value of the expression to the right of the "=" operator. The following example shows how a dynamic variable changes its type based on its value.

dynamic dynamicVariable = 1;

dynamicVariable=“Hello world”;

Important Points

In most of the cases, the dynamic type behaves like object types.

You can get the actual type of the dynamic variable at runtime by using GetType() method.

It does not support the intellisense in visual studio.

The compiler does not throw an error on dynamic type at compile time if there is no type checking for dynamic type.

The type of the variable is decided by the compiler at run time.

If the variable does not initialized it will not throw an error.
