Use the Sort method to sort the KeyValuePairs collection.Firstly, set the collection −var myList = new List(); // adding elements myList.Add(new KeyValuePair(1, 20)); myList.Add(new KeyValuePair(2, 15)); myList.Add(new KeyValuePair(3, 35)); myList.Add(new KeyValuePair(4, 50)); myList.Add(new KeyValuePair(5, 25));To sort, use the Sort() method. With that, we have used the CompareTo() method to ... Read More

MySQL LIKE operator is used to select data based on pattern matching. Similarly, we can use LIKE operator with views to select particular data based on pattern matching from the base table. To understand this concept we are using the base table ‘student_info’ having the following data −mysql> Select * from Student_info; ... Read More

Use DateTime.Subtract to get the difference between two dates in C#.Firstly, set two dates −DateTime date1 = new DateTime(2018, 8, 27); DateTime date2 = new DateTime(2018, 8, 28);Use the Subtract method to get the difference −TimeSpan t = date2.Subtract(date1);The following is the complete code −Example Live Demousing System; using System.Threading; using ...

Use the DaysInMonth to display the number of days in a month.Add the year and month as a parameter for the DaysInMonth() method −DateTime.DaysInMonth(2018, 8);The following is an example −Example Live Demousing System; using System.Collections.Generic; using System.Linq; public class Demo {    public static void Main() {       Console.WriteLine("Today ... Read More

Use the TimeSpan.Zero to represent the exact representation of no time i.e −00:00:00Set an object for TimeSpan −TimeSpan ts;Now, the TimeSpan.Zero is used to display no time −TimeSpan ts = TimeSpan.Zero;Example Live Demousing System; using System.Linq; public class Demo {    public static void Main() {       TimeSpan ts ...

It gets an array of the names of constants in an enumeration. The following is the syntax −Enum.GetNames(Type)Here, Type is an enumeration type.The following is an example −Example Live Demousing System; class Demo {    enum Vehicle {       Car,       Motorbike,       Truck, ... Read More

To handle range of bytes, use Buffer Type in C#. Its method Buffer.BlockCopy copies the bytes from one byte array to another byte array.Example Live Demousing System; class Demo {    static void Main() {       // byte arrays       byte[] b1 = new byte[] {39, 45, ... Read More

Read individual bytes using GetByte() method in C# −Set an array −int[] arr = { 3, 4, 12 };Now, use Buffer.GetByte() to display the array elements and to read individual bytes −for (int i = 0; i < Buffer.ByteLength(arr); i++) {    Console.WriteLine(Buffer.GetByte(arr, i)); }The following is the code −Example Live ...
