Application State is a feature in ASP.NET that allows and data across an application. It provides a way to share data among users and .

Example:

Let's say we have an ASP.NET application that allows users to add items to a shopping cart. We want to keep of the total number of items in the cart for all users. We can use the Application State to store and this information.


// Storing the total number of items in the cart
Application["TotalItems"] = 10;

In the above example, we are storing the total number of items in the cart in the Application State using the key “TotalItems”. This value will be accessible to all users and sessions within the application.


//  the total number of items from the cart
int totalItems = (int)Application["TotalItems"];

In the above example, we are retrieving the total number of items from the Application State using the key “TotalItems”. We cast the retrieved value to an integer to use it in our code.
