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>
