BOXING: Converting value type to referenc type.
Here we go with an example,

ArrayList instance = new ArrayList()
//In the above line of code,ArrayList is a reference
type.Add some items to the arraylist. For example,

instance.Add(1);
instance.Add(100);
instance.Add(3);
//3 items added to the arraylist.
//Integer valuee 3 is value type.Adding 3 to the reference
type(here it's arraylist) is boxing.
i.e., Converting value type to referenc type.

UNBOXING:Converting Reference type to value type.
Below is an example, retrives the items from the
arraylist.

foreach (int item in arrayList)
Console.WriteLine(item);

Here arraylist(referenec type) will have 3 values in the
list, which we added above.
Adding this arraylist items to an int variable[here int
variable is "item"] is unboxing.
i.e.,converting the reference type to value type.

Hope you would have understood.
Thanks
