How to initialize Session variable

Here's an example of how you can assign an int value to a session variable:

// Set session variable
int value = 123;
Session["MyVariable"] = value;

In the above example, the session variable named "MyVariable" is assigned the value of 123.

Later, when you need to retrieve the value from the session variable, you can cast it back to an int:

// Get session variable
int retrievedValue = (int)Session["MyVariable"];

In this case, the value stored in the session variable "MyVariable" is cast back to an int and assigned to the retrievedValue variable.
