c# 声明类的时候初始化类

The task is to create/declare a list with an initializer list in C#.

任务是在C＃中使用初始化列表创建/声明一个列表 。

C＃清单 (C# List)

A list is used to represent the list of the objects, it is represented as List<T>, where T is the type of the list objects/elements.

列表用于表示对象的列表，它表示为List <T> ，其中T是列表对象/元素的类型。

A list is a class which comes under System.Collections.Generic package, so we have to include it first.

列表是System.Collections.Generic包下的一个类，因此我们必须首先包含它。

具有初始化的列表声明 (List declaration with initialization)

To declare and initialize a list with the elements/objects, we use the following syntax,

要使用元素/对象声明和初始化列表 ，我们使用以下语法，

    List<T> list_name= new List<T> {list_of_objects/elements};

Here, T is the type and list_name is the name of the list.

在这里， T是类型， list_name是列表的名称。

Examples:

例子：

    //an integer list
List<int> int_list = new List<int> { 10, 20, 30, 40, 50 };
//a string list 
List<string> str_list = new List<string>{
"Manju", "Amit", "Abhi", "Radib", "Prem"
};

Here, int_list is a list of integer elements and str_list is a list of string elements.

在这里， int_list是整数元素的列表， str_list是字符串元素的列表。

C＃程序使用初始化来创建/声明列表 (C# program to create/declare a list with initialization )

using System;
using System.Text;
using System.Collections.Generic;
namespace Test
{
class Program
{
static void Main(string[] args)
{
//an integer list
List<int> int_list = new List<int> { 10, 20, 30, 40, 50 };
//a string list 
List<string> str_list = new List<string>{
"Manju", "Amit", "Abhi", "Radib", "Prem"
};
//printing list elements
Console.WriteLine("int_list elements...");
foreach (int item in int_list)
{
Console.Write(item + " ");
}
Console.WriteLine();
Console.WriteLine("str_list elements...");
foreach (string item in str_list)
{
Console.Write(item + " ");
}
Console.WriteLine();
//hit ENTER to exit
Console.ReadLine();
}
}
}

Output

输出量

int_list elements...
10 20 30 40 50
str_list elements...
