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 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
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 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 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 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 IndexOf() method of array class in C# searches for the specified object and returns the index of the first occurrence within the entire one-dimensional Array.We have set the array.int[] arr = new int[10]; arr[0] = 100; arr[1] = 200; arr[2] = 300; arr[3] = 400; arr[4] = 500; arr[5] = 600; arr[6] = 700; arr[7] = 800; arr[8] = 900; arr[9] = 1000;Now use the IndexOf() method and set the element for which you want the index, for example, I have set it for element 800.int a = Array.IndexOf(arr, 800);The following is the example showing the usage of IndexOf(, ...

A main method is static since it is available to run when the C# program starts. It is the entry point of the program and runs without even creating an instance of the class.The Main method states what the class does when executed and instantiates other objects and variables.The following shows how to add a Main() method.Exampleusing system; namespace demo { class helloworld { static void main(string[] args) { console.writeline("hello world"); console.readkey(); } } }As you can see in the above example.static void Main(string[] ...

The return statement is used to return value. When a program calls a function, the program control is transferred to the called function. A called function performs a defined task and when its return statement is executed or when its function-ending closing brace is reached, it returns the program control back to the main program.The following is an example to learn about the usage of return statement in C#. Here, we are finding the factorial of a number and returning the result using the return statement.while (n != 1) { res = res * n; n = n ... Read More
With StringBuilder, you can expand the number of characters in the string. String cannot be changed once it is created, but StringBuildercan be expanded. It does not create a new object in the memory.Initialize StringBuilder.StringBuilder str = new StringBuilder();Let us see an example to learn how to work with StringBuilder in C#.Example Live Demousing System; using System.Text; public class Program { public static void Main() { StringBuilder str = new StringBuilder("Web World!!",30); str.Replace("World", "Arena"); Console.WriteLine(str); } }OutputWeb Arena!!Above the Replace() method of StringBuilder is used to to replace a string in C#.
