The GetValue() method of array class in C# gets the value at the specified position in the one-dimensional Array. The index is specified as a 32-bit integer.We have set the array values first using the Array.CreateInstance method.Array arr = Array.CreateInstance(typeof(String), 3, 6); arr.SetValue("One", 0, 0); arr.SetValue("Two", 0, 1); arr.SetValue("Three", 0, 2); arr.SetValue("Four", 0, 3); arr.SetValue("Five", 1, 4); arr.SetValue("Six", 1, 5); arr.SetValue("Seven", 1, 2); arr.SetValue("Eight", 1, 3);Then loop throught the array length. This will display all the values using the GetValue() method.for (int i = 0; i < a; i++) for (int j = 0; j < b; j++) Console.WriteLine( arr.GetValue(i, ... Read More

The GetUpperBound() method of array class in C# gets the upper bound of the specified dimension in the Array.Firstly, set the array and get the upperbound as shown below −arr.GetUpperBound(0).ToString()The following is an example stating the usage of GetUpperBound() method in C#.Example Live Demousing System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Demo {    class Program {       static void Main(string[] args) {          Array arr = Array.CreateInstance(typeof(String), 6);          arr.SetValue("One", 0);          arr.SetValue("Two", 1);          arr.SetValue("Three", 3);          arr.SetValue("Four", 4);     ...

Set the unsorted list first.int[] list = {87, 45, 56, 22, 84, 65};Now use a nested for loop to sort the list that is passed to a function.for(int i=0; ilt; arr.Length; i++) {    for(int j=i+1; j

The GetType() method of array class in C# gets the Type of the current instance (Inherited from Object).To get the type.Type tp = value.GetType();In the below example, we are checking the int value using the type.if (tp.Equals(typeof(int))) Console.WriteLine("{0} is an integer data type.", value)The following is the usage of GetType() method in C#.Exampleusing System public class Program {    public static void Main() {       object[] values = { (int) 100, (long) 17111};       foreach (var value in values) {          Type tp = value.GetType();          if (tp.Equals(typeof(int)))     ...

Set a list with some values. Here, we have a list of strings.var cars = new List() {"Mercedes", "Audi", "Jaguar" };To sort, simply use Sort() method.cars.Sort();The following is an example showing how to sort a list in C#.Example Live Demousing System; using System.Collections.Generic; public class Program {    public static void Main() {       var cars = new List() {"Mercedes", "Audi", "Jaguar" };       Console.WriteLine("Original Array =");       foreach (var name in cars) {          Console.WriteLine(name);       }       // sort       cars.Sort();       ...

The GetLowerBound() method of array class in C# gets the lower bound of the specified dimension in the Array.Firstly, set the array and get the lower bound as shown below −arr.GetLowerBound(0).ToString()The following is an example stating the usage of GetLowerBound() method in C#.Example Live Demousing System; using System.Collections.Generic; using System.Linq; using System.Text; namespace lower {    class Program {       static void Main(string[] args) {          Array arr = Array.CreateInstance(typeof(String), 3);          arr.SetValue("Car", 0);          arr.SetValue("Truck", 1);          arr.SetValue("Motorbike", 2);          Console.WriteLine("Lower Bound {0}",arr.GetLowerBound(0).ToString());          Console.ReadLine();       }    } }OutputLower Bound 0

The GetLongLength method in C# gets a 64-bit integer that represents the number of elements in the specified dimension of the Array.First, set the array.long[,] arr2= new long[15, 35];For a specified dimension of the array, set the index in the GetLongMethod() method like −long len2 = arr2.GetLongLength(0);Let us see the complete example.Example Live Demousing System; class Program {    static void Main() {       int[,] arr = new int[20, 30];       int len = arr.GetLength(0);       Console.WriteLine(len);       long[,] arr2= new long[15, 35];       long len2 = arr2.GetLongLength(0);       Console.WriteLine(len2);    } }Output20 15

The GetLength gets a 32-bit integer that represents the number of elements in the specified dimension of the Array.First, set the array.int[,] arr = new int[20, 30];For a specified dimension of the array, set the index in the GetLength() method like −Arr.GetLength(1);Example Live Demousing System; class Program {    static void Main() {       int[,] arr = new int[20, 30];       int len = arr.GetLength(1);       Console.WriteLine(len);    } }Output30

The Directory class in C# is used to manipulate the directory structure. It has methods to create, move, remove directories.The following are some of the methods of the Directory class.Sr.No.Method & Description1CreateDirectory(String)Creates all directories and subdirectories in the specified path2Delete(String)Deletes an empty directory3Exists(String)Whether the given path refers to an existing directory4GetCreationTime(String)Gets the creation date and time of a directory.5GetCurrentDirectory()Gets the current working directory6GetFiles(String)Let us learn about the usage of GetFiles() method in Directory class. It displays all the files in the specified directory.Exampleusing System; using System.IO; class Program {    static void Main() {       // Get all ... Read More

The CopyTo() method in C# is used to copy elements of one array to another array. In this method, you can set the starting index from where you want to copy from the source array.The following is the syntax.CopyTo(dest, index);Here dest = destination arrayindex= starting indexThe following is an example showing the usage of CopyTo(, ) method of array class in C#.Example Live Demousing System; class Program {    static void Main() {       int[] arrSource = new int[4];       arrSource[0] = 5;       arrSource[1] = 9;       arrSource[2] = 1;     ...
