The Random.Next() method in C# is used to return a non-negative random integer.SyntaxThe syntax is as follows −public virtual int Next (); public virtual int Next (int maxVal);Above, the maxVal parameter is the exclusive upper bound of the random number to be generated.ExampleLet us now see an example − Live Demousing System; public class Demo {    public static void Main(){       Random r = new Random();       Console.WriteLine("Random numbers.....");       for (int i = 1; i

The SortedDictionary.Value property in C# is used to get a collection containing the values in the SortedDictionary.SyntaxThe syntax is as follows −public System.Collections.Generic.SortedDictionary.ValueCollection Values { get; }ExampleLet us now see an example − Live Demousing System; using System.Collections; using System.Collections.Generic; public class Demo {    public static void Main(){       SortedDictionarysortedDict = new SortedDictionary();       sortedDict.Add(1, "Ultrabook");       sortedDict.Add(2, "Alienware");       sortedDict.Add(3, "Notebook");       sortedDict.Add(4, "Connector");       sortedDict.Add(5, "Flash Drive");       sortedDict.Add(6, "SSD");       sortedDict.Add(7, "HDD");       sortedDict.Add(8, "Earphone");       Console.WriteLine("SortedDictionary ...
