You can use string's Join()method, like this:

您可以使用字符串的Join()方法,如下所示:

Console.WriteLine("My array: {0}",
    string.Join(", ", myArray.Select(v => v.ToString()))
);

This will print array elements converted to string, separated by ", ".

这将打印转换为 的数组元素,以string分隔", "

You can use the following one liner to print an array

您可以使用下面的一个衬垫打印一个数组

int[] array = new int[] { 1 , 2 , 3 , 4 };

Array.ForEach( array , x => Console.WriteLine(x) );

You can write an extension method something like this

你可以写一个像这样的扩展方法

namespace ConsoleApplication12
{
    class Program
    {

        static void Main(string[] args)
        {
            var items = new []{ 1, 2, 3, 4, 5 };
            items.PrintArray();
        }
    }

    static class ArrayExtensions
    {
        public static void PrintArray<T>(this IEnumerable<T> elements)
        {
            foreach (var element in elements)
            {
                Console.WriteLine(element);
            }
        }
    }
}

I like @dasblinkenlight solution, but I'd like to note that the select statement is not nessasary.

我喜欢@dasblinkenlight 解决方案,但我想指出 select 语句不是必需的。

This code produces the same result for an array of strings:

此代码为字符串数组生成相同的结果:

string[] myArray = {"String 1", "String 2", "More strings"};
Console.WriteLine("My array: {0}", string.Join(", ", myArray)); 

I find it a little easier on the eyes having less code to read.

我发现阅读更少代码的眼睛更容易一些。
