The Tuple class represents a 3-tuple, which is called triple. 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 three 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.Item3 − Get the value of the current Tuple object's third component.ExampleLet us now see an example to implement the 3-tuple in C# ...

The Tuple class represents a 1-tuple, which is called singleton. 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 one property −Item1 − Get the value of the current Tuple object's first component.ExampleLet us now see an example to implement the 1-tuple in C# −using System; public class Demo {    public static void Main(string[] args) {       Tuple tuple = new ...

If you want to return more than one value from a class method, then use C# Tuples. To create tuples in C#< this class provides a static method. Tuples introduced in .NET 4.0.ExampleLet us now see an example to implement Tuple in C# −using System; public class Demo {    public static void Main(string[] args) {       Tuple tuple = new Tuple(2, "Tom");       if (tuple.Item1 == 150) {          Console.WriteLine(tuple.Item1);       }       if (tuple.Item2 == "Tom") {          Console.WriteLine(tuple.Item2);       }    } }OutputThis will produce the following output −Tom

The Math.Truncate() method in C# is used to compute an integral part of a number, which is Double or Decimal.Syntaxpublic static decimal Truncate(decimal val1) public static double Truncate(double val2)Above, there are two syntaxes. The value val1 is the decimal number to truncate, whereas val2 is the double number to truncate.ExampleLet us now see an example to implement Math.Truncate() method −using System; public class Demo {    public static void Main(){       Decimal val1 = 25.46467m;       Decimal val2 = 45.9989m;       Decimal val3 = 678.325m;       Console.WriteLine(Math.Truncate(val1));       Console.WriteLine(Math.Truncate(val2));   ...

The Math.Tanh() method in C# is used to return the hyperbolic tangent of the specified angle.Syntaxpublic static double Tanh (double val);Above, Val is the angle.ExampleLet us now see an example to implement Math.Tanh() method −using System; public class Demo {    public static void Main(){       double val1 = 30.0;       double val2 = (60 * (Math.PI)) / 180;       Console.WriteLine(Math.Tanh(val1));       Console.WriteLine(Math.Tanh(val2));    } }OutputThis will produce the following output −1 0.780714435359268ExampleLet us see another example to implement Math.Tanh() method −using System; public class Demo {    public static void Main(){ ...

The CharEnumerator.MoveNext() method in C# is used to increments the internal index of the current CharEnumerator object to the next character of the enumerated string.Syntaxpublic bool MoveNext ();Let us now see an example to implement the CharEnumerator.MoveNext() method −Exampleusing System; public class Demo {    public static void Main(){       string strNum = "john";       CharEnumerator ch = strNum.GetEnumerator();       Console.WriteLine("HashCode = "+ch.GetHashCode());       Console.WriteLine("Get the Type = "+ch.GetType());       while (ch.MoveNext())          Console.Write(ch.Current + " ");       // disposed       ch.Dispose();   ...

The CharEnumerator.GetType() method in C# is used to get the type of the current instance.Syntaxpublic Type GetType();Let us now see an example to implement the CharEnumerator.GetType() method −Exampleusing System; public class Demo {    public static void Main(){       string strNum = "john";       CharEnumerator ch = strNum.GetEnumerator();       Console.WriteLine("HashCode = "+ch.GetHashCode());       Console.WriteLine("Get the Type = "+ch.GetType());       while (ch.MoveNext())          Console.Write(ch.Current + " ");       // disposed       ch.Dispose();       // this will show an error since we disposed ...

The CharEnumerator.GetHashCode() method in C# returns a hash code for the current object.Syntaxpublic virtual int GetHashCode ();Let us now see an example to implement the CharEnumerator.GetHashCode() method −Exampleusing System; public class Demo {    public static void Main(){       string strNum = "john";       CharEnumerator ch = strNum.GetEnumerator();       Console.WriteLine("HashCode = "+ch.GetHashCode());       while (ch.MoveNext())          Console.Write(ch.Current + " ");       // disposed       ch.Dispose();       // this will show an error since we disposed the object above       // Console.WriteLine(ch.Current);    } }OutputThis will produce the following output −HashCode = 30571253 j o h n

The Dictionary. Count property in C# gets the number of key/value pairs in the Dictionary.syntaxpublic int Count { get; }Let us now see an example to implement the Dictionary. Count property −Exampleusing System; using System.Collections.Generic; public class Demo {    public static void Main(){       Dictionary dict =       new Dictionary();       dict.Add("One", "Chris");       dict.Add("Two", "Steve");       dict.Add("Three", "Messi");       dict.Add("Four", "Ryan");       dict.Add("Five", "Nathan");       Console.WriteLine("Count of elements = "+dict.Count);       Console.WriteLine("Key/value pairs...");       foreach(KeyValuePair res in dict){ ...
