عنصر النشر

عنصر النشر ..

using System;

int[] a = [1, 2, 3];
int[] b = [4, 5, 6];
int[] all = [..a, ..b];
Console.WriteLine(string.Join(",", all)); // 1,2,3,4,5,6

مزج عناصر النشر والعناصر المفردة

using System;

int[] middle = [2, 3, 4];
int[] result = [1, ..middle, 5];
Console.WriteLine(string.Join(",", result)); // 1,2,3,4,5

الإضافة في البداية والنهاية

using System;

int[] core = [10, 20, 30];
int[] withHead = [0, ..core];
int[] withTail = [..core, 40];
Console.WriteLine(string.Join(",", withHead)); // 0,10,20,30
Console.WriteLine(string.Join(",", withTail)); // 10,20,30,40

النشر من مصادر متعددة

using System;
using System.Collections.Generic;

List<string> x = ["a", "b"];
List<string> y = ["c"];
List<string> z = ["d", "e"];
List<string> merged = [..x, ..y, ..z];
Console.WriteLine(string.Join(",", merged)); // a,b,c,d,e

النشر من أنواع مجموعات مختلفة

using System;
using System.Collections.Generic;

int[] arr = [1, 2];
List<int> list = [3, 4];
int[] combined = [..arr, ..list];
Console.WriteLine(string.Join(",", combined)); // 1,2,3,4

نشر IEnumerable

using System;
using System.Linq;

var evens = Enumerable.Range(1, 6).Where(n => n % 2 == 0);
int[] result = [0, ..evens];
Console.WriteLine(string.Join(",", result)); // 0,2,4,6

بناء المجموعات تدريجيًا

using System;

int[] baseline = [1, 2, 3];
int[] extra = [4, 5];
int[] full = [..baseline, ..extra, 6];
Console.WriteLine(full.Length); // 6

الترتيب مهم

using System;

int[] a = [1, 2];
int[] b = [3, 4];
Console.WriteLine(string.Join(",", [..a, ..b])); // 1,2,3,4
Console.WriteLine(string.Join(",", [..b, ..a])); // 3,4,1,2

عناصر النشر في مقابل Concat

using System;
using System.Linq;

int[] a = [1, 2];
int[] b = [3, 4];
// old
int[] oldWay = a.Concat(b).ToArray();
// new
int[] newWay = [..a, ..b];
Console.WriteLine(oldWay.SequenceEqual(newWay)); // True

النشر داخل Span

using System;

ReadOnlySpan<int> head = [1, 2];
ReadOnlySpan<int> tail = [3, 4];
int[] joined = [..head, ..tail];
Console.WriteLine(string.Join(",", joined)); // 1,2,3,4

دمج عملي

using System;

string[] defaults = ["--verbose", "--color"];
string[] userArgs = ["--output=log.txt"];
string[] finalArgs = [..defaults, ..userArgs];
Console.WriteLine(string.Join(" ", finalArgs));
