本指南展示瞭如何在 c# 中按字母順序對單詞進行排序。c# 中有一個內建函式，我們可以使用它對列表進行排序。
在 C# 中使用 Sort() 方法按字母順序對列表進行排序
首先，using System.Collections.Generic;，這是你需要匯入的庫才能在 c# 中使用列表。我們需要使用 Sort() 對列表進行排序。
之後，我們需要使用比較器來比較兩個字串。例如，看一下下面的程式碼。
citizens.Sort((x, y) => string.Compare(x.Name, y.Name));
在上面的程式碼行中，citizens 是列表，我們比較公民的姓名以按字母順序對公民列表進行排序。
在 C# 中使用 foreach 迴圈來列印按字母順序排列的列表
using System;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Collections.Generic; // library import to use list;
namespace list_sort {
class Program {
static void Main(string[] args) {
List<Person> citizens = new List<Person>(5); // Creating List Of Person having size 5;
// Adding Persons in List
citizens.Add(new Person("Mark", "Zuker", "Silicon Valley United States", 50));
citizens.Add(new Person("Bill ", "Gates", "Silicon Valley United States", 70));
citizens.Add(new Person("Jeff", "Bezoz", "Silicon Valley United States", 40));
citizens.Add(new Person("Elon", "Musk", "Silicon Valley United States", 20));
citizens.Add(new Person("Antony", "Gates", "Silicon Valley United States", 30));
Console.WriteLine(":::::::::::::::::::::::::::::::Before Sorting ::::::::::::::::::::::::");
// Prinring The List Names...
foreach (Person p in citizens) { // Loop through List with foreach
Console.WriteLine(p.Name);
}
Console.WriteLine(":::::::::::::::::::::::::::::::After Sorting :::::::::::::::::");
// Problem # Sort List of Citizens According to Citizen Names orderby-alphabetical-order
citizens.Sort((x, y) => string.Compare(x.Name, y.Name));
foreach (Person p in citizens) // Prniting After alphabetical Sort.
{ // Loop through List with foreach
Console.WriteLine(p.Name);
}
Console.ReadKey(); // to Stay On Screen.
}
}
class Person {
public String Name;
public String LastName;
public String Address;
public int age;
public Person(String Name, String LastName, String Address, int Age) {
this.Name = Name;
this.LastName = LastName;
this.Address = Address;
this.age = Age;
}
}
}
首先，我們建立了一個 citizen 列表，然後新增了姓名、地址和年齡。我們在排序列表之前列印它，然後在排序列表之後列印它。
輸出：
:::::::::::::::::::::::::::::::Before Sorting ::::::::::::::::::::::::
Mark
Bill
Jeff
Elon
Antony
:::::::::::::::::::::::::::::::After Sorting :::::::::::::::::
Antony
Bill
Elon
Jeff
Mark
