Get the keys in the SortedList using the keys property of SortedList class in C#. We have first set the SortedList property with elements.SortedList sl = new SortedList(); sl.Add("ST0", "One"); sl.Add("ST1", "Two"); sl.Add("ST2", "Three"); sl.Add("ST3", "Four"); sl.Add("ST4", "Five"); sl.Add("ST5", "Six"); sl.Add("ST6", "Seven");Now use the keys property to get the keys.ICollection key = sl.Keys;The following is the complete code to implement keys property of SortedList class.Example Live Demousing System; using System.Collections; namespace Demo { class Program { static void Main(string[] args) { SortedList sl = new SortedList(); sl.Add("ST0", "One"); ...

Use the IsFixedSize property in C# to get a value indicating whether the SortedList has a fixed size.The following is an example showing SorteList with the usage of IsFixedSize property.Example Live Demousing System; using System.Collections; namespace Demo { class Program { static void Main(string[] args) { SortedList s = new SortedList(); s.Add("S1", "Maths"); s.Add("S2", "Science"); s.Add("S3", "English"); s.Add("S4", "Economics"); Console.WriteLine("IsFixedSize = " + s.IsFixedSize); } } }OutputIsFixedSize = FalseWe ...

Use the IsReadOnly property to get a value indicating whether the SortedList is read-only or not.You can try to run the following code to implement IsReadOnly property in C#.Here, we have set the SortedList first.SortedList s = new SortedList();Added elements.s.Add("S001", "Jack"); s.Add("S002", "Henry");Now check for IsReadOnly.Console.WriteLine("IsReadOnly = " + s.IsReadOnly);The following is the complete code.Example Live Demousing System; using System.Collections; namespace Demo { class Program { static void Main(string[] args) { SortedList s = new SortedList(); s.Add("S001", "Jack"); s.Add("S002", "Henry"); Console.WriteLine("IsReadOnly ...

Character constantsCharacter literals are enclosed in single quotes. For example, 'x' and can be stored in a simple variable of char type. A character literal can be a plain character (such as 'x'), an escape sequence (such as '\t'), or a universal character (such as '\u02C0').Certain characters in C# are preceded by a backslash. They have special meaning and they are used to represent like newline () or tab (\t).Example Live Demousing System; namespace Demo { class MyApplication { static void Main(string[] args) { Console.WriteLine("Welcome\t to the website"); Console.ReadLine(); ...

Use the File.exists method in C# to check if a file exits in C# or not.Firstly, check whether the file is present in the current directory.if (File.Exists("MyFile.txt")) { Console.WriteLine("The file exists."); }After that check whether the file exist in a directory or not.if (File.Exists(@"D:\myfile.txt")) { Console.WriteLine("The file exists."); }Let us see the complete example to check if a file exists in C#.Example Live Demousing System; using System.IO; class Demo { static void Main() { if (File.Exists("MyFile.txt")) { Console.WriteLine("File exists..."); } else { Console.WriteLine("File does ...

Use the isFixedSize property of Hashtable class to get a value indicating whether the Hashtable has a fixed size.The following is an example showing how to work with IsFixedSize property.Example Live Demousing System; using System.Collections; namespace Demo { class Program { static void Main(string[] args) { Hashtable ht = new Hashtable(); ht.Add("D01", "Finance"); ht.Add("D02", "HR"); ht.Add("D03", "Operations"); Console.WriteLine("IsFixedSize = " + ht.IsFixedSize); Console.ReadKey(); } } }OutputIsFixedSize = FalseAbove we ...

Firstly, set the string to be checked.string s = "timetime";Now set two counters for two halves of the string.int []one = new int[MAX_CHAR]; int []two = new int[MAX_CHAR];Check for both the halves of the string.for (int i = 0, j = l - 1; i < j; i++, j--) { one[str[i] - 'a']++; two[str[j] - 'a']++; }The following is the complete code to check whether both the halves of the string have same set of characters or not in C#.Example Live Demousing System; class Demo { static int MAX_CHAR = 26; static bool findSameCharacters(string str) { ...

To set the starting position of a background image in JavaScript, use the backgroundposition property. It allows you to set the position of the image.ExampleYou can try to run the following code to learn how to set all the position of a background image with JavaScript −Live Demo body { background-repeat: no-repeat; } Click to Set background image function display() { document.body.style.backgroundImage = "url('https://www.tutorialspoint.com/html5/images/html5-mini-logo.jpg')"; document.body.style.backgroundPosition="top right"; }
Firstly, set the two numbers.int one = 250; int two = 200;Now pass those numbers to the following function.public int RemainderFunc(int val1, int val2) { if (val2 == 0) throw new Exception("Second number cannot be zero! Cannot divide by zero!"); if (val1 < val2) throw new Exception("Number cannot be less than the divisor!"); else return (val1 % val2); }Above we have checked for two conditions i.e.If the second number is zero, an exception occurs.If the first number is less than the second number, an exception occurs.To return remainder of two numbers, the following is ...

Use the Number() method in JavaScript to convert to Number. You can try to run the following code to learn how to convert ["demo"] to Number in JavaScript −ExampleLive Demo Convert ["demo"] to Number var myVal = ["demo"]; document.write("Number: " + Number(myVal));
