Linq ToArray()方法

LINQ中的ToArray()运算符用于将集合中的输入元素转换为Array。

LINQ ToArray()运算符的语法

使用LINQ ToArray()运算符将集合转换为数组的语法。

C#代码

string[] countryarray = countries.ToArray();

In the above syntax, we are converting the collection of "countries" to an Array.

方法语法中的LINQ ToArray()运算符示例

在本例中，我们在方法语法中使用LINQ ToArray()运算符将输入集合项转换为新数组。

using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
//Create array countries of string type containing the data.
            string[] countries = { "Uk", "Us", "Russia", "India", "Argentina", "Australia", "China" };
//countries.ToArray() is used to convert the collection of data into the form of array
            string[] countryarray = countries.ToArray();
//foreach loop is used to print the name of the countries
            foreach (string s in countryarray)
            {
                Console.WriteLine(s);
            }
                Console.ReadLine();
        }
    }
}

In the above example, we have a List of type string "countries." By using the ToArray() method, we converted the list of "countries" List to an Array. To access these elements, we have iterated the array in a foreach loop and displayed it on the screen.

查询语法中的Linq ToArray()运算符

The example of using 查询语法中的Linq ToArray()运算符 is:

using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] countries = { "India", "China", "US", "Russia", "Argentina", "Australia", "UK" };
//query syntax is used to convert the collection of data into the form of array
            string[] countrArray = (from x in countries select x).ToArray();
            foreach (string s in countrArray)
            {
                Console.WriteLine(s);
            }
                Console.ReadLine();
        }
    }
}
