c# - 无法初始化类型“int”错误

Question

我在 C# 中有一个简单的代码

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

namespace MyProject
{
  public static class Class1
  {
    public static int[] Iparray = new int { 12, 9, 4, 99, 120, 1, 3, 10 };
  }
}

但是在（Ctrl++ Shift）B上显示的错误是

Cannot initialize type 'int' with a collection initializer because it does not implement 'System.Collections.IEnumerable'

我正在使用 vs 2010 和 .NET 框架 4

谢谢你们

Answer 1

你缺少括号。像这样：

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

Answer 2

您可以通过三种方式定义int数组：

 public static int[] Iparray = { 12, 9, 4, 99, 120, 1, 3, 10 };

 public static int[] Iparray = new[] { 12, 9, 4, 99, 120, 1, 3, 10 };
 public static int[] Iparray = new int[] { 12, 9, 4, 99, 120, 1, 3, 10 };

Answer 3

new int[] { 12, 9, 4, 99, 120, 1, 3, 10 };

Answer 4

尝试这个：-

public static int[] a = new int[] {12, 9, 4, 99, 120, 1, 3, 10 };

代替

public static int[] Iparray = new int { 12, 9, 4, 99, 120, 1, 3, 10 };

Answer 5

您只是错过了方括号；

namespace MyProject
{
  public static class Class1
  {
    public static int[] Iparray = new int[] { 12, 9, 4, 99, 120, 1, 3, 10 };
  }
}

• Arrays (C# Programming Guide)
• Single-Dimensional Arrays (C# Programming Guide)

int声明数组的替代方法；

• int[] Iparray = { 12, 9, 4, 99, 120, 1, 3, 10 };

• int[] Iparray = new[] { 12, 9, 4, 99, 120, 1, 3, 10 };

Answer 6

int[] values = new int[] { 1, 2, 3 };
or this:

int[] values = new int[3];
values[0] = 1;
values[1] = 2;
values[2] = 3;

Answer 7

将 [] 添加到您的代码中

public static int[] Iparray = new int[] { 12, 9, 4, 99, 120, 1, 3, 10 };
