The BitConverter.ToInt64() method in C# is used to return a 64-bit signed integer converted from eight bytes at a specified position in a byte array.SyntaxThe syntax is as follows −public static long ToInt64 (byte[] val, int begnIndex);Above, val is the byte array, whereas begnIndex is the beginning position within val.Let us now see an example −Example Live Demousing System; public class Demo {    public static void Main() {       byte[] arr = { 0, 10, 15, 20, 26, 30, 34, 42, 50};       Console.WriteLine("Byte Array = {0} ", BitConverter.ToString(arr));       for (int i = ...

The SByte.Equals() method in C# is used to return a value indicating whether this instance is equal to a specified object or SByte.SyntaxThe syntax is as follows −public bool Equals (sbyte ob); public override bool Equals (object ob);Above, the ob parameter for an SByte value to compare to this instance, whereas the ob parameter for the 2nd syntax is an object to compare with this instance.ExampleLet us now see an example − Live Demousing System; public class Demo {    public static void Main() {       sbyte s1 = 10;       sbyte s2 = 100;     ...
