This method(comes under System.Collections namespace) is used to return the object at the top of the Stack without removing it. This method is similar to the Pop method, but Peek does not modify the Stack.
public virtual object Peek ();
Return Value: It returns the Object at the top of the Stack.
Exception: Calling Peek() method on empty stack will throw InvalidOperationException. So always check for elements in the stack before retrieving elements using the Peek() method.
Below given are some examples to understand the implementation in a better way.
Total number of elements in the Stack are : 6 Element at the top is : 6th Element Element at the top is : 6th Element Total number of elements in the Stack are : 6
System.InvalidOperationException: Stack empty.
