Create a tuple.var myTuple = Tuple.Create(1, 2.5M, "Amit", "100");Now to access tuple elements, use the properties.To access first element.myTuple.Item1To access second element.myTuple.Item2In the same way, for other elements, use the properties as shown below −Example Live Demousing System; public class Program {    public static void Main() {       ...

Use the Math.BigMul() method to find the product of two 32-bit numbers.The following are our two numbers.int one = 345272828; int two = 887685744;Now, get the product.long res; res = Math.BigMul(one, two);Example Live Demousing System; using System.Globalization; class Demo {    static void Main() {       int one = ...

Use the Convert.ToUInt64() method to convert a specified value to a 64-bit unsigned integer.The following is our char.char ch = 'a';Now, let’s convert it to a 64-bit unsigned integer.ulong res; res = Convert.ToUInt64(ch);Here is the complete example.Example Live Demousing System; public class Demo {    public static void Main() {   ...

Firstly, set a Dictionary collection with elements.Dictionary d = new Dictionary() {    {1, "Applianes"},    {2, "Clothing"},    {3, "Toys"},    {4, "Footwear"},    {5, "Accessories"} };Now, let’s say you need to check whether key 5 exists or not. For that, use ContainsKey() method. It returns True if key ... Read More

To get the Upperbound and Lowerbound, use the GetUpperBound() GetLowerBound() methods in C#, respectively.The parameter to be set under these methods is the dimensions i.e.Let’s say our 3D array is −int[, , ] arr = new int[2, 3, 4];For a three-dimensional arrays, dimension 0.arr.GetUpperBound(0) arr.GetLowerBound(0)For a three-dimensional arrays, dimension 1.arr.GetUpperBound(1) ...

Byte represents an 8-bit unsigned integer.Implicit conversion of an 8-bit unsigned integer (Byte) to a Decimal is possible. Let us see how.Here’s our Byte value.byte val = 16;To implicitly convert, just assign the value as shown below −decimal dec; dec = val;Let us see the complete example.Example Live Demousing System; public ...

Orders elements in a sequence using ThenBy() method.We have the following string array.string[] str = { "AAA", "AAAA", "A", "AAAAA", "AAAAAAAAA" };Now, use Lambda Expressions and set a condition inside the ThenBy() method to sort the strings according to the number of characters they have.IEnumerable res = str.AsQueryable() .OrderBy(alp => ...

To get the bounds of a three-dimensional array, use the GetUpperBound() GetLowerBound() methods in C#.The parameter to be set under these methods is the dimensions i.e.Let’s say our array is −int[, , ] arr = new int[3, 4, 5];For a three-dimensional arrays, dimension 0.arr.GetUpperBound(0) arr.GetLowerBound(0)For a three-dimensional arrays, dimension 1.arr.GetUpperBound(1) ...

Set two sequences.double[] arr1 = { 10.2, 15.6, 23.3, 30.5, 50.2 }; double[] arr2 = { 15.6, 30.5, 50.2 };To get the difference between both the above arrays, use Except() method.IEnumerable res = arr1.AsQueryable().Except(arr2);The following is the complete code.Example Live Demousing System; using System.Linq; using System.Collections.Generic; class Demo {    static ...

The Single() method returns the only element that satisfies a condition. If more than one such element is visible, then an error is thrown.The following is our string array.string[] str = { "jack", "tom", "henry", "time"};Now, use the Single() method to get each element. Then, we have used Lambda Expression ... Read More
