无LINQ重复：

float[] floats = System.Array.ConvertAll(new float[16], v => 1.0f);

For Class initialization:
var page1 = new Class1();
var page2 = new Class2();
var pages = new UIViewController[] { page1, page2 };

带有表达式的平凡解决方案。注意，使用NewArrayInit，您可以只创建一维数组。

NewArrayExpression expr = Expression.NewArrayInit(typeof(int), new[] { Expression.Constant(2), Expression.Constant(3) });
int[] array = Expression.Lambda<Func<int[]>>(expr).Compile()(); // compile and call callback

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)"

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();

您还可以创建动态数组，即，在创建数组之前，您可以先向用户询问数组的大小。

Console.Write("Enter size of array");
int n = Convert.ToInt16(Console.ReadLine());

int[] dynamicSizedArray= new int[n]; // Here we have created an array of size n
Console.WriteLine("Input Elements");
for(int i=0;i<n;i++)
{
     dynamicSizedArray[i] = Convert.ToInt32(Console.ReadLine());
}

Console.WriteLine("Elements of array are :");
foreach (int i in dynamicSizedArray)
{
    Console.WriteLine(i);
}
Console.ReadKey();
