The Char.ConvertToUtf32(String, Int32) method in C# is used to convert the value of a UTF-16 encoded character or surrogate pair at a specified position in a string into a Unicode code point.SyntaxFollowing is the syntax −public static int ConvertToUtf32 (string str, int index);Above, str is the string that contains a character or surrogate pair. The index parameter is the index position of the character or surrogate pair in str.ExampleLet us now see an example to implement the Char.ConvertToUtf32(String, Int32) method −using System; public class Demo { public static void Main(){ int utf = 0x046; ...

The DateTime.DaysInMonth() method in C# is used to return the number of days in the specified month and year. For example, 31 for month value 1 i.e. January.SyntaxFollowing is the syntax −public static int DaysInMonth (int year, int month);ExampleLet us now see an example to implement the DateTime.DaysInMonth() method −using System; public class Demo { public static void Main() { DateTime date1 = new DateTime(2019, 08, 20, 6, 20, 40); DateTime date2 = new DateTime(2019, 06, 20, 6, 20, 40); Console.WriteLine("DateTime 1 = {0:dd} {0:y}, {0:hh}:{0:mm}:{0:ss} ", date1); ...

The Tuple class represents a 2-tuple, which is called pair. A tuple is a data structure that has a sequence of elements.It is used in −Easier access to a data set.Easier manipulation of a data set.To represent a single set of data.To return multiple values from a methodTo pass multiple values to a methodIt has two properties −Item1 − Get the value of the current Tuple object's first component.Item2 − Get the value of the current Tuple object's second component.ExampleLet us now see an example to implement the 2-tuple in C# −using System; public class Demo { public static ...

The UInt16.Equals() method in C# returns a value indicating whether this instance is equal to a specified object or UInt16.SyntaxFollowing is the syntax −public override bool Equals (object ob); public bool Equals (ushort ob);Above, the parameter ob for the 1st syntax is an object to compare to this instance and the parameter ob for the 2nd syntax is the 16-bit unsigned integer to compare to this instance.ExampleLet us now see an example to implement the UInt16.Equals() method −using System; public class Demo { public static void Main(){ ushort val1 = 52; ushort val2 ... Read More
The UInt16.CompareTo() method in C# is used to compare the current instance to a specified object or UInt16 and returns an indication of their relative values.SyntaxFollowing is the syntax −public int CompareTo (object val); public int CompareTo (ushort val;Above, the value for the 1st syntax is an object to compare. The value for 2nd syntax is an unsigned integer to compare.The return value is 0 if the current instance is equal to value. It’s less than zero if the current instance is less than val. The return value is more than zero if the current instance is greater than the ... Read More
