Second SkipWhile Prototype
<source lang="csharp">using System; using System.Linq; using System.Collections; using System.Collections.Generic; public class MainClass {
public static void Main() { string[] presidents = {"ant", "arding", "arrison", "Hayes", "Hoover", "ackson"}; IEnumerable<string> items = presidents.SkipWhile((s, i) => s.Length > 4 && i < 10); foreach (string item in items) Console.WriteLine(item); }
}</source>
SkipWhile Prototype
<source lang="csharp">using System; using System.Linq; using System.Collections; using System.Collections.Generic; public class MainClass {
public static void Main() { string[] presidents = {"Ant", "arding", "arrison", "ayes", "Hoover", "ackson"}; IEnumerable<string> items = presidents.SkipWhile(s => s.StartsWith("A")); foreach (string item in items) Console.WriteLine(item); }
}</source>
SkipWhile with condition
<source lang="csharp">using System; using System.Collections.Generic; using System.Linq; using System.Text; public class MainClass{ public static void Main() {
int[] numbers = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 }; var allButFirst3Numbers = numbers.SkipWhile(n => n % 3 != 0); Console.WriteLine("All elements starting from first element divisible by 3:"); foreach (var n in allButFirst3Numbers) { Console.WriteLine(n); } }
}</source>
SkipWhile with index
<source lang="csharp">using System; using System.Collections.Generic; using System.Linq; using System.Text; public class MainClass{ public static void Main() {
int[] numbers = { 5, 4, 8, 6, 7, 2, 0 }; var laterNumbers = numbers.SkipWhile((n, index) => n >= index); Console.WriteLine("All elements starting from first element less than its position:"); foreach (var n in laterNumbers) { Console.WriteLine(n); } }
}</source>
Use SkipWhile with index
<source lang="csharp">using System; using System.Collections; using System.Collections.Generic; using System.Text; using System.Linq; public class MainClass{
public static void Main(){ int[] numbers = { 1, 3, 5, 4}; var query = numbers.TakeWhile(( n, index) => n >= index); var query2 = numbers.SkipWhile(( n, index) => n >= index); }
}</source>
