The DateTime.ToBinary() method in C# is used to serialize the current DateTime object to a 64-bit binary value that can be used to recreate the DateTime object. The return value is a 64-bit signed integer.SyntaxFollowing is the syntax −public long ToBinary ();ExampleLet us now see an example to implement the DateTime.ToBinary() method −using System; public class Demo { public static void Main() { DateTime d = new DateTime(2019, 10, 10, 8, 10, 40); Console.WriteLine("Date = {0}", d); long res = d.ToBinary(); Console.WriteLine("64-bit binary value : {0}", res); ...

The Tuple class represents a 2-tuple, which is called pair. A tuple is a data structure that has a sequence of elements.ExampleLet us now see an example to implement the 2-tuple in C# −using System; public class Demo { public static void Main(string[] args) { Tuple tuple = new Tuple("jack", "steve"); Console.WriteLine("Value = " + tuple.Item1); if (tuple.Item1 == "jack") { Console.WriteLine("Exists: Tuple Value = " +tuple.Item1); } if (tuple.Item2 == "david") { Console.WriteLine("Exists: Tuple Value ...

The DateTimeOffset.CompareTo() method in C# is used to compares the current DateTimeOffset object to a specified DateTimeOffset object and indicates whether the current object is earlier than, the same as, or later than the second DateTimeOffset object.It returns an integer value, 0 − If this object is later than ValSyntaxFollowing is the syntax −public int CompareTo (DateTimeOffset val);Above, Val is the object to compare.ExampleLet us now see an example to implement the DateTimeOffset.CompareTo() method −using System; public class Demo { public static void Main() { DateTimeOffset dateTimeOffset1 = new DateTimeOffset(2019, 09, 09, 8, 20, 10, new ...

The DateTime.SpecifyKind() method in C# is used to create a new DateTime object that has the same number of ticks as the specified DateTime but is designated as either local time, Coordinated Universal Time (UTC), or neither, as indicated by the specified DateTimeKind value.SyntaxFollowing is the syntax −public static DateTime SpecifyKind (DateTime d, DateTimeKind kind);Above, the parameter d is the DateTime, whereas kind is One of the enumeration values that indicates whether the new object represents local time, UTC, or neither.ExampleLet us now see an example to implement the DateTime.SpecifyKind() method −using System; using System.Globalization; public class Demo { ... Read More
The Decimal.ToUInt16() method in C# is used to convert the value of the specified Decimal to the equivalent 16-bit unsigned integer.SyntaxFollowing is the syntax −public static ushort ToUInt16 (decimal val);Above, the value val is the decimal number to convert.ExampleLet us now see an example to implement the Decimal.ToUInt16() method −using System; public class Demo { public static void Main(){ Decimal val = 875.647m; Console.WriteLine("Decimal value = "+val); ushort res = Decimal.ToUInt16(val); Console.WriteLine("16-bit unsigned integer = "+res); } }OutputThis will produce the following output −Decimal value = ... Read More
The Math.BigMul() method in C# is used to calculate the full product of two 32-bit numbers. The method returns an Int64 integer with the production of both the numbers.SyntaxFollowing is the syntax −public static long BigMul (int val1, int val2);Here, val1 is the 1st number to multiply, whereas val2 is the 2nd number.ExampleLet us now see an example to implement Math.BigMul() method −using System; public class Demo { public static void Main(){ int val1 = Int32.MaxValue; int val2 = Int32.MaxValue; Console.WriteLine("Product of two numbers = " + Math.BigMul(val1, val2)); ... Read More
The Math.Atan2() method in C# is used to return the angle whose tangent is the quotient of two specified numbers.SyntaxFollowing is the syntax −public static double Atan2 (double val1, double val2);Above, val1 is the y coordinate, whereas val2 is the x coordinate.ExampleLet us now see an example to implement Math.Atan2() method −using System; public class Demo { public static void Main(){ double val1 = 3.0; double val2 = 1.0; double angle, radians; radians = Math.Atan2(val1, val2); angle = radians * (180/Math.PI); ... Read More
The Char.ToString() method in C# is used to convert the value of this instance to its equivalent string representation.SyntaxFollowing is the syntax −public override string ToString ();ExampleLet us now see an example to implement the Char.ToString() method −using System; public class Demo { public static void Main(){ char ch = 'p'; Console.WriteLine("Value = "+ch); char res1 = Char.ToLowerInvariant(ch); Console.WriteLine("Lowercase Equivalent = "+res1); string res2 = ch.ToString(); Console.WriteLine("String Equivalent = "+res2); } }OutputThis will produce the following output −Value = p ...
