hi只是为了添加另一种方式：从此页面：https://learn.microsoft.com/it-it/dotnet/api/system.linq.enumerable.range?view=netcore-3.1

如果您想生成0到9的指定范围内的整数序列，可以使用此表单：

using System.Linq
.....
public int[] arrayName = Enumerable.Range(0, 9).ToArray();

创建和初始化对象数组的另一种方法。这与上面@Amol发布的示例类似，只是这一个使用了构造函数。一点点多态性洒了进来，我无法抗拒。

IUser[] userArray = new IUser[]
{
    new DummyUser("abc@cde.edu", "Gibberish"),
    new SmartyUser("pga@lna.it", "Italian", "Engineer")
};

上下文类：

interface IUser
{
    string EMail { get; }       // immutable, so get only an no set
    string Language { get; }
}

public class DummyUser : IUser
{
    public DummyUser(string email, string language)
    {
        m_email = email;
        m_language = language;
    }

    private string m_email;
    public string EMail
    {
        get { return m_email; }
    }

    private string m_language;
    public string Language
    {
        get { return m_language; }
    }
}

public class SmartyUser : IUser
{
    public SmartyUser(string email, string language, string occupation)
    {
        m_email = email;
        m_language = language;
        m_occupation = occupation;
    }

    private string m_email;
    public string EMail
    {
        get { return m_email; }
    }

    private string m_language;
    public string Language
    {
        get { return m_language; }
    }

    private string m_occupation;
}

Enumerable.Repeat(String.Empty, count).ToArray()

将创建重复“count”次的空字符串数组。若您希望使用相同但特殊的默认元素值初始化数组。注意引用类型，所有元素都将引用同一对象。

对于C#声明中的多维数组，请赋值。

public class Program
{
    static void Main()
    {
        char[][] charArr = new char[][] { new char[] { 'a', 'b' }, new char[] { 'c', 'd' } };

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

}

创建自定义类数组的示例

下面是类定义。

public class DummyUser
{
    public string email { get; set; }
    public string language { get; set; }
}

这是初始化数组的方法：

private DummyUser[] arrDummyUser = new DummyUser[]
{
    new DummyUser{
       email = "abc.xyz@email.com",
       language = "English"
    },
    new DummyUser{
       email = "def@email.com",
       language = "Spanish"
    }
};

int[] array = new int[4]; 
array[0] = 10;
array[1] = 20;
array[2] = 30;

or

string[] week = new string[] {"Sunday","Monday","Tuesday"};

or

string[] array = { "Sunday" , "Monday" };

并且在多维阵列中

    Dim i, j As Integer
    Dim strArr(1, 2) As String

    strArr(0, 0) = "First (0,0)"
    strArr(0, 1) = "Second (0,1)"

    strArr(1, 0) = "Third (1,0)"
    strArr(1, 1) = "Fourth (1,1)"
