The Any method checks whether any of the element in a sequence satisfy a specific condition or not.If any element satisfy the condition, true is returned.Let us see an example.int[] arr = {5, 7, 10, 12, 15, 18, 20};Now, using Any() method, we will check whether any of the element in the above array is greater than 10 or not.arr.AsQueryable().All(val => val > 5);If any of the element satisfies the condition, then True is returned.Let us see the complete example.Example Live Demousing System; using System.Linq; class Demo {    static void Main() {       int[] arr = {5, 7, ...

To convert a Double value to an Int64 value, use the Convert.ToInt64() method.Int64 represents a 64-bit signed integer.Let’s say the following is our double value.double val = 23.951213e12;Now to convert it to Int64.long longVal = Convert.ToInt64(val);Let us see the complete example.Example Live Demousing System; public class Demo {    public static void Main() {       double val = 23.951213e12;       long longVal = Convert.ToInt64(val);       Console.WriteLine("Converted double {0:E} to Int64 {1:N0} value ", val, longVal);    } }OutputConverted double 2.395121E+013 to Int64 23,951,213,000,000 value

To convert a Byte value to an Int32 value, use the Convert.ToInt32() method.Int32 represents a 32-bit signed integer.Let’s say the following is our Byte value.byte val = Byte.MaxValue;;Now to convert it to Int32.int intVal = Convert.ToInt32(val);Let us see the complete example.Example Live Demousing System; public class Demo {    public static void Main() {       byte val = Byte.MaxValue;;       int intVal = Convert.ToInt32(val);       Console.WriteLine("Converted byte {0} to Int32 {1} value ", val, intVal);    } }OutputConverted byte 255 to Int32 255 value

To convert an Int32 value to a decimal, use the Convert.ToDecimal() method.Int32 represents a 32-bit signed integer.Let’s say the following is our Int32 value.int val = 2923;Now to convert it to decimal.decimal decVal = Convert.ToDecimal(val);Let us see the complete example.Example Live Demousing System; public class Demo {    public static void Main() {       int val = 2923;       decimal decVal = Convert.ToDecimal(val);       Console.WriteLine("Converted Int32 {0} to decimal {1:N2} value ", val, decVal);    } }OutputConverted Int32 2923 to decimal 2,923.00 value

The exception thrown when a null reference is passed to a method that does not accept it as a valid argument.Let us see an example.When we set a null parameter to int.Parse() method, then ArgumentNullException is thrown as shown below −Exampleusing System; class Demo {    static void Main() {       string val = null;       int res = int.Parse(val); // error is thrown    } }OutputThe following error is thrown when the above program is compiled since we have passed a null value.Unhandled Exception: System.ArgumentNullException: Value cannot be null.

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) arr.GetLowerBound(1)For a three-dimensional arrays, dimension 2.arr.GetUpperBound(2) arr.GetLowerBound(2)Let us see the entire example.Example Live Demousing System; class Program {    static void Main() {       int[, , ] arr = new int[3, 4, 5];       Console.WriteLine("Dimension 0 Upper Bound: {0}", arr.GetUpperBound(0).ToString());       Console.WriteLine("Dimension 0 Lower Bound: ...

Let’s say our three-dimensional array is −int[,,] arr = new int[3,4,5];To get the height and width i.e. the rows and columns.Array.GetLength(0) – for rows Array.GetLength(1) – for columnsExample Live Demousing System; class Program {    static void Main() {       int[,,] arr = new int[3,4,5];       Console.WriteLine(arr.GetLength(0));       Console.WriteLine(arr.GetLength(1));       Console.WriteLine(arr.GetLength(2));    } }Output3 4 5

To get the rank of a three-dimensional array, use the Rank property.Set a three-dimensional array.int[,,] arr = new int[3,4,5]Now get the rank.arr.RankLet us see the complete code.Exampleusing System; class Program {    static void Main() {       int[,,] arr = new int[3,4,5]       Console.WriteLine("Dimensions of Array : " + arr.Rank);    } }

Merge sequences using predicate with Zip method.Here are our arrays to be merged.int[] intArray = { 10, 20, 30, 40 }; string[] stringArray = { "Jack", "Tim", "Henry", "Tom" };Now let’s use the Zip method to merge both the arrays.intArray.AsQueryable().Zip(stringArray, (one, two) => one + " " + two)The following is our code.Example Live Demousing System; using System.Linq; using System.Collections.Generic; public class Demo {    public static void Main() {       int[] intArray = { 10, 20, 30, 40 };       string[] stringArray = { "Jack", "Tim", "Henry", "Tom" };       var mergedSeq = intArray.AsQueryable().Zip(stringArray, (one, two) => one + " " + two);       foreach (var ele in mergedSeq)       Console.WriteLine(ele);    } }Output10 Jack 20 Tim 30 Henry 40 Tom

Use the LastorDefault() method to return the last element of a sequence or a default value if element isn’t there.The following is our empty list.List val = new List { };Now the following will not be able to display the last element since the list is empty. Therefore, the default would get display and error won’t be shown.val.AsQueryable().LastOrDefault();The following is the code.Example Live Demousing System; using System.Collections.Generic; using System.Linq; class Demo {    static void Main() {       List val = new List { };       double d = val.AsQueryable().LastOrDefault();       Console.WriteLine("Default Value = "+d); ...
