To find a character except for a newline, use the Metacharacter. (period). You can try to run the following code to find a character −Example JavaScript Regular Expression var myStr = "We provide websites! We provide content!"; var reg = /p.o/g; var match = myStr.match(reg); document.write(match);
Set query in a select clause using the into operator.The following is our list with Employee details −IList employee = new List() { new Employee() { EmpID = 1, EmpName = "Tom", EmpMarks = 90, Rank = 8} , new Employee() { EmpID = 2, EmpName = "Anne", EmpMarks = 60, Rank = 21 } , new Employee() { EmpID = 3, EmpName = "Jack", EmpMarks = 76, Rank = 18 } , new Employee() { EmpID = 4, EmpName = "Amy" , EmpMarks = 67, Rank = 20} , };Now, fetch employee name that ends ...

Javascript date setUTCMilliseconds() method sets the milliseconds for a specified date according to universal time.The following is the parameter for setUTCMilliseconds(millisecondsValue) −millisecondsValue − A number between 0 and 999, representing the milliseconds.ExampleYou can try to run the following code to set the milliseconds for a specified date according to universal time − JavaScript setUTCMilliseconds Method var dt = new Date( "Aug 28, 2008 23:30:00" ); dt.setUTCMilliseconds( 1200 ); document.write( dt );
Use the BufferHeight gets or sets the height of the buffer area.Use the property like this −Console.BufferHeightLet us see the complete example.Example Live Demousing System; class Demo { static void Main() { Console.WriteLine("Buffer height (rows) = "+Console.BufferHeight); } }OutputBuffer height (rows) = 0
We have a list without any element.List val = new List { };To display the default and avoid any error, use the FirstorDefault() method.val.AsQueryable().FirstOrDefault();You can also change the value to be displayed as default.Let us see the code.Example Live Demousing System; using System.Collections.Generic; using System.Linq; class Demo { static void Main() { List val = new List{ }; float a = val.AsQueryable().FirstOrDefault(); Console.WriteLine("Default Value = "+a); if (a == 0.0f) { a = 0.1f; } Console.WriteLine("Default Float value updated = "+a); } }OutputDefault Value = 0 Default Float value updated = 0.1
TimeSpan Seconds() is part of time, whereas TimeSpan TotalSeconds() converts entire time to seconds.Let us first see the TimeSpan Seconds() method.Example Live Demousing System; using System.Linq; public class Demo { public static void Main() { TimeSpan ts = new TimeSpan(0, 100, 0, 20, 0); // seconds Console.WriteLine(ts.Seconds); } }Output20Now, let us see how TotalSeconds works for the same TimeSpan value.Example Live Demousing System; using System.Linq; public class Demo { public static void Main() { TimeSpan ts = new TimeSpan(0, 100, 0, 20, 0); // ...

The Convert.ToChar method is used to convert a specified value to a Unicode integer.We have declared an sbyte variable.sbyte byteVal = 200;Now, use the Convert.ToChar() method to convert the sbyte value to a Unicode integer.charVal = Convert.ToChar(b);Let us see another example.Example Live Demousing System; public class Demo { public static void Main() { sbyte[] byteVal = { 92, 111, 115 }; char charVal; foreach (sbyte b in byteVal) { charVal = Convert.ToChar(b); Console.WriteLine("{0} converted to '{1}'", b, charVal); } } }Output92 converted to '\' 111 converted to 'o' 115 converted to 's'
The Convert.ToDateTime method converts a given value to a DateTime value.The following is my string.string myDateString; myDateString = "09/09/2018";Now, let us convert it using the Convert.ToDateTime() method.DateTime result; result = Convert.ToDateTime(myDateString);Here is the complete example.Example Live Demousing System; public class Demo { public static void Main() { string myDateString; DateTime result; myDateString = "09/09/2018"; result = Convert.ToDateTime(myDateString); Console.WriteLine("'{0}' converted to {1}", myDateString, result); } }Output'09/09/2018' converted to 9/9/2018 12:00:00 AM
Like any other programming languages such as C, C++, Java, we can easily display start pattern programs in C#.Let us see them one by one.Example Live Demousing System.IO; using System; class Program { static void Main() { for (int i = 1; i
To delete rows in a table in JavaScript, use the DOM deleteRow() method.ExampleYou can try to run the following code to learn how to delete rows in a table. The code deletes rows one at a time −Live Demo function captionFunc(x) { document.getElementById(x).createCaption().innerHTML = "Demo Caption"; } One Two Three Four Five Six
