The Random.NextDouble() method in C# is used to return a random floating-point number that is greater than or equal to 0.0, and less than 1.0.SyntaxThe syntax is as follows −public virtual double NextDouble ();ExampleLet us now see an example − Live Demousing System; public class Demo {    public static void Main(){       Random r1 = new Random();       Random r2 = new Random();       Byte[] arr = new Byte[2];       r1.NextBytes(arr);       Console.WriteLine("Random numbers in the byte array...");       for (int i = 0; i < 2; i++) ...

The SortedDictionary.Remove() method in C# is used to remove the element with the specified key from the SortedDictionary.OutputThe syntax is as follows −public bool Remove (TKey key);Above, the parameter key is the key of the element to remove.ExampleLet us now see an example − Live Demousing System; using System.Collections; using System.Collections.Generic; public class Demo {    public static void Main(){       SortedDictionary sortedDict = new SortedDictionary();       sortedDict.Add(100, "Mobile");       sortedDict.Add(200, "Laptop");       sortedDict.Add(300, "Desktop");       sortedDict.Add(400, "Speakers");       sortedDict.Add(500, "Headphone");       sortedDict.Add(600, "Earphone");       ...

The SortedDictionary.Keys property in C# is used to get a collection containing the keys in the SortedDictionary.SyntaxThe syntax is as follows −public System.Collections.Generic.SortedDictionary.KeyCollection Keys { get; }ExampleLet us now see an example − Live Demousing System; using System.Collections; using System.Collections.Generic; public class Demo {    public static void Main(){       SortedDictionary sortedDict = new SortedDictionary();       sortedDict.Add(1, "SUV");       sortedDict.Add(2, "MUV");       sortedDict.Add(3, "Utility Vehicle");       sortedDict.Add(4, "AUV");       sortedDict.Add(5, "Hatchback");       sortedDict.Add(6, "Convertible");       Console.WriteLine("SortedDictionary key-value pairs...");       IDictionaryEnumerator demoEnum = sortedDict.GetEnumerator(); ...

The SByte.ToString() method in C# is used to convert the numeric value of this instance to its equivalent string representation.SyntaxThe syntax is as follows −public override string ToString ();ExampleLet us now see an example − Live Demousing System; public class Demo {    public static void Main(){       sbyte s1 = 10;       sbyte s2 = 100;       Console.WriteLine("Value of S1 = "+s1);       Console.WriteLine("Value of S2 = "+s2);       int res = s1.CompareTo(s2);       if (res > 0)          Console.WriteLine("s1 > s2");       ...

The BitConverter.ToInt32() method in C# is used to return a 32-bit signed integer converted from four bytes at a specified position in a byte array.SyntaxThe syntax is as follows −public static int ToInt32 (byte[] val, int begnIndex);Above, val is the byte array, whereas begnIndex is the beginning position within val.ExampleLet us now see an example − Live Demousing System; public class Demo {    public static void Main(){       byte[] arr = { 10, 20, 30, 40, 50};       Console.WriteLine("Byte Array = {0} ", BitConverter.ToString(arr));       for (int i = 1; i < arr.Length - ...

The Single.CompareTo() method in C# is used to compare this instance to a specified object or to another Single instance and returns an integer that indicates whether the value of this instance is less than, equal to, or greater than the value of the specified object or the other Single instance.The return value is less than zero if the 1st instance is less than 2nd. The return value is 0 if both are equal and greater than zero is 0, if the 1st instance is more than 2nd.SynchronizedThe syntaxes are as follows −public int CompareTo (float val); public int CompareTo ...

The BitConverter.ToDouble() method in C# is used to return a double-precision floating-point number converted from eight bytes at a specified position in a byte array.SynchronizedThe syntax is as follows −public static double ToDouble (byte[] val, int begnIndex);Above, val is the byte array, whereas begnIndex is the beginning position within val.ExampleLet us now see an example − Live Demousing System; public class Demo {    public static void Main(){       byte[] arr = { 0, 2, 5, 10, 20, 26, 34, 42, 50, 58, 66, 74, 82, 89, 97, 107, 115};       Console.WriteLine("Byte Array = {0} ", BitConverter.ToString(arr)); ...

The BitConverter.ToInt16() method in C# is used to return a 16-bit signed integer converted from two bytes at a specified position in a byte array.SyntaxThe syntax is as follows −public static short ToInt16 (byte[] val, int begnIndex);Above, val is the byte array, whereas begnIndex is the beginning position within val.ExampleLet us now see an example − Live Demousing System; public class Demo {    public static void Main(){       byte[] arr = { 0, 0, 7, 10, 18, 20, 25, 26, 32};       Console.WriteLine("Byte Array = {0} ", BitConverter.ToString(arr));       for (int i = 1; ...
