  • Last Updated : 18 Feb, 2019

ToString method is inherited from the Object class which is used to get a string that represents the current object. It can also apply on the Stack. It returns a string which represents the current stack object.

Syntax: public virtual string ToString ();

Return Value: This method returns a String representation of the collection.

Example 1: In the below program, GetType() method is used to get the type of the current object. It will clarify whether the given Stack object is converted into the string or not.

        Stack st = new Stack();
  
        // Use Push() method
        // to add elements to 
        // the stack
        st.Push("Welcome");
        st.Push("To");
        st.Push("Geeks");
        st.Push("For");
        st.Push("Geeks");
          
        Console.WriteLine("The type of st before "+
                 "ToString Method: "+st.GetType());
          
        Console.WriteLine("After ToString Method: ");
  
        foreach(string str in st)
        {
            // Using ToString() method
            Console.WriteLine(str.ToString());
        }
  
        Console.WriteLine("The type of st after "+
            "ToString Method: "+st.ToString().GetType());
    }
}
