To find how many elements are added in the Stack class, you need to use the Count property.Let us first add elements in the Stack −Stack st = new Stack(); st.Push('H'); st.Push('I'); st.Push('J'); st.Push('K'); st.Push('L'); st.Push('M'); st.Push('N'); st.Push('O');Now count the number of elements in the Stack −Console.WriteLine("Count: "+st.Count);Let us see the complete code −Example Live Demousing System; using System.Collections; namespace Demo {    class Program {       static void Main(string[] args) {          Stack st = new Stack();          st.Push('H');          st.Push('I');          st.Push('J'); ...

Use the Count property to find the count of elements of the Queue class. Set elements like the following declaration −Queue q = new Queue(); q.Enqueue(1); q.Enqueue(2); q.Enqueue(3); q.Enqueue(4);Then use the Count property to count the elements −q.CountThe following is an example showing how to work with Count property in Queue Class −Example Live Demousing System; using System.Collections; namespace Demo {    class Program {       static void Main(string[] args) {          Queue q = new Queue();          q.Enqueue(1);          q.Enqueue(2);          q.Enqueue(3);          q.Enqueue(4);          Console.WriteLine("Total elements: {0} ", q.Count);              Console.ReadKey();       }    } }OutputTotal elements: 4

To find the count of elements of Hashtable class, use the Count property. Firstly, set the Hashtable class with elements −Hashtable ht = new Hashtable(); ht.Add("One", "Tom"); ht.Add("Two", "Jack"); ht.Add("Three", "Peter"); ht.Add("Four", "Russel"); ht.Add("Five", "Brad"); ht.Add("Six", "Bradley"); ht.Add("Seven", "Steve"); ht.Add("Eight", "David");Now, count the number of elements using the Count property −ht.CountThe following is the complete example to learn about the usage of Hashtable Count property in C#.Example Live Demousing System; using System.Collections; namespace Demo {    class Program {       static void Main(string[] args) {          Hashtable ht = new Hashtable();     ...

Count the number of elements in the BitArray class using the Count property.Let us first set our BitArray class −BitArray arr = new BitArray(10);Now use the Count property as shown below −Example Live Demousing System; using System.Collections; public class Demo {    public static void Main() {       BitArray arr = new BitArray(10);       Console.WriteLine( "Count: {0}", arr.Count );    } }OutputCount: 10

The capacity property in SortedList class has the maximum size of the SortedList.The default capacity of a SortedList is 16.You can try to run the following the code to implement Capacity property of SortedList class in C# −Example Live Demousing System; using System.Collections; namespace Demo {    class Program {       static void Main(string[] args) {          SortedList s = new SortedList();          s.Add("S1", "Maths");          s.Add("S2", "Science");          s.Add("S3", "English");          s.Add("S4", "Economics");          Console.WriteLine("Capacity = " ...

The Count property in the ArrayList class counts the number of elements in the ArrayList.Firstly, add elements to the ArrayList −ArrayList arrList = new ArrayList(); arrList.Add(98); arrList.Add(55); arrList.Add(65); arrList.Add(34);Then get the count of the array list −arrList.CountThe following is the code to implement Count property in C# −Example Live Demousing System; using System.Collections; class Demo {    public static void Main() {       ArrayList arrList = new ArrayList();       arrList.Add(98);       arrList.Add(55);       arrList.Add(65);       arrList.Add(34);       Console.WriteLine("Count = " + arrList.Count);    } }OutputCount = 4

The capacity property in ArrayList class gets or sets the number of elements that the ArrayList can contain.Capacity is always greater than count. For capacity property −arrList.CapacityThe default capacity is 4. If 5 elements are there, then its capacity is doubled and would be 8. This goes on.You can try to run the following the code to implement Capacity property in C#. This also shows what we discussed above −Example Live Demousing System; using System.Collections; class Demo {    public static void Main() {       ArrayList arrList = new ArrayList();       arrList.Add(19);       arrList.Add(44); ...

To find the number of dimensions of an array, use the Rank property.arr.RankHere, arr is our array −int[, ] arr = new int[3, 4];If you also want to get the rows and columns it has, then use the GetLength property −arr.GetLength(0); arr.GetLength(1);The following is the complete code −Example Live Demousing System; class Program {    static void Main() {       int[, ] arr = new int[3, 4];       Console.WriteLine(arr.GetLength(0));       Console.WriteLine(arr.GetLength(1));       // Length       Console.WriteLine(arr.Length);       Console.WriteLine("Upper Bound: {0}", arr.GetUpperBound(0).ToString());       Console.WriteLine("Lower Bound: ...

To find the length of an array, use the Array.Length() method.ExampleLet us see an example − Live Demousing System; class Program {    static void Main(){       int[] arr = new int[10];       // finding length       int arrLength = arr.Length;       Console.WriteLine("Length of the array: "+arrLength);    } }OutputLength of the array: 10Above, we have an array −int[] arr = new int[10];Now to find the length, we used the Length() method −int arrLength = arr.Length;

The sizeof() datatype returns the size of a data type. Let’s say you need to find the size of int datatype −sizeof(int);For double datatypesizeof(double);Let us see the complete example to find the size of various datatypes −Example Live Demousing System; namespace Demo {    class Program {       static void Main(string[] args) {          Console.WriteLine("The size of int is {0}", sizeof(int));          Console.WriteLine("The size of int is {0}", sizeof(char));          Console.WriteLine("The size of short is {0}", sizeof(short));          Console.WriteLine("The size of long is ...
