JavaScript date setUTCDate() method sets the day of the month for a specified date according to universal time.The following is the parameter for setUTCDate(dayValue) −dayValue − An integer from 1 to 31, representing the day of the month.ExampleYou can try to run the following code to set the day of the month for a specified date − JavaScript setUTCDate Method var dt = new Date( "Oct 15, 2017 23:30:00" ); dt.setUTCDate( 20 ); document.write( dt );
The method matches instances of a pattern and is used to extract value based on a pattern.Let us see hoe to check for a valid URL.For that, pass the regex expression in the Matches method.MatchCollection mc = Regex.Matches(text, expr);Above, the expr is our expression that we have set to check for valid URL."^(http|http(s)?://)?([\w-]+\.)+[\w-]+[.com|.in|.org]+(\[\?%&=]*)?”The text we have set to check is a URL i.e.https://demo.comLet us see the complete code.Example Live Demousing System; using System.Text.RegularExpressions; namespace Demo { class Program { private static void showMatch(string text, string expr) { MatchCollection mc = Regex.Matches(text, expr); ...

JavaScript date setUTCFullYear() method sets the full year for a specified date according to universal time.The following are the parameters for setUTCFullYear(yearValue[, monthValue[, dayValue]]) −yearValue − An integer specifying the numeric value of the year, for example, 2008.monthValue − An integer between 0 and 11 representing the months January through December.dayValue − An integer between 1 and 31 representing the day of the month. If you specify the dayValue parameter, you must also specify the monthValue.ExampleYou can try to run the following code to set the full year for a specified date according to universal time − ...

AsQueryable() method is used to get an IQueryable reference.Let us see an example to find sum of integer values.Firstly, set an integer array.var arr = new int[] { 100, 200, 300, 400 };Now to find the sum, use the Queryable Sum() and AsQueryable() method.Queryable.Sum(arr.AsQueryable());The following is the complete code.Example Live Demousing System; using System.Linq; class Demo { static void Main() { var arr = new int[] { 100, 200, 300, 400 }; int res = Queryable.Sum(arr.AsQueryable()); Console.WriteLine("Sum: "+res); } }OutputSum: 1000
JavaScript date setUTCHours() method sets the hour for a specified date according to local time. The following is the parameter for setUTCHours(hoursValue[, minutesValue[, secondsValue[, msValue]]]) −hoursValue − An integer between 0 and 23, representing the hour.minutesValue − An integer between 0 and 59, representing the minutes.secondsValue − An integer between 0 and 59, representing the seconds. If you specify the secondsValue parameter, you must also specify the minutesValue.msValue − A number between 0 and 999, representing the milliseconds. If you specify the msValue parameter, you must also specify the minutesValue and secondsValue.ExampleYou can try to run the following code to ... Read More
Get the maximum value from a sequence using the Max() method.Let’s say the following is our list.List list = new List { 200, 400, 600, 800, 1000, 1200, 1400, 1600, 1800, 2000 };Use the Max() method to get the largest element.list.AsQueryable().Max();Example Live Demousing System; using System.Collections.Generic; using System.Linq; class Demo { static void Main() { List list = new List { 200, 400, 600, 800, 1000, 1200, 1400, 1600, 1800, 2000 }; foreach(long ele in list) Console.WriteLine(ele); // getting largest element long max_num = list.AsQueryable().Max(); Console.WriteLine("Largest number = {0}", max_num); } }Output200 400 600 800 1000 1200 1400 1600 1800 2000 Largest number = 2000
Get the minimum value from a sequence using the Min() method in C#.The following is our list.List list = new List { 1, 2, 3, 4, 5, 6 };Now, use Queryable Min() method to get minimum element.list.AsQueryable().Min();Exampleusing System; using System.Collections.Generic; using System.Linq; class Demo { static void Main() { List list = new List { 1, 2, 3, 4, 5, 6 }; foreach(long ele in list) { Console.WriteLine(ele); } // getting lowest element long min_num = list.AsQueryable().Min(); Console.WriteLine("Smallest number = {0}", mix_num); } }
The ondragover event triggers when the dragged element is over the drop target.ExampleYou can try to run the following code to learn how to implement ondragover event in JavaScript −Live Demo .drag { float: left; width: 100px; height: 35px; border: 2px dashed #876587; margin: 15px; padding: 10px; } ...

The following is our Hashtable −Hashtable h = new Hashtable(); h.Add(1, "Jack"); h.Add(2, "Henry"); h.Add(3, "Ben"); h.Add(4, "Chris");To remove an item, use the Remove() method. Here, we are removing the 3rd element.h.Remove(3);Let us see the complete example.Example Live Demousing System; using System.Collections; public class Demo { public static void Main() { Hashtable h = new Hashtable(); h.Add(1, "Jack"); h.Add(2, "Henry"); h.Add(3, "Ben"); h.Add(4, "Chris"); Console.WriteLine("Initial list:"); foreach (var key in h.Keys ) { Console.WriteLine("Key = ...

JavaScript date getUTCDay() method returns the day of the week in the specified date according to universal time. The value returned by getUTCDay() is an integer corresponding to the day of the week: 0 for Sunday, 1 for Monday, 2 for Tuesday, and so on.ExampleYou can try to run the following code to return the day of the week in the specified date − JavaScript getUTCDay Method var dt = new Date( "January 15, 2018 20:15:20" ); document.write("getUTCDay() : " + dt.getUTCDay() );
