如何在C#中清空数组？

Question

我正在使用该函数Array.Clear()清空数组,但它会生成错误.这是我使用的代码:

private int[] activeFielderNumber = new int[10];
private string[] activeFielderAction = new string[10];  
....
...
....
Array.Clear(activeFielderNumber, 0, activeFielderNumber.Length);
Array.Clear(activeFielderAction, "", activeFielderAction.Length);

错误是:

error CS0103: The name `Array' does not exist in the current context

我怎么解决这个问题？

Answer 1

你用过了吗？

using System;

还有一点需要纠正:

Array.Clear(activeFielderAction, "", activeFielderAction.Length);

它应该是

Array.Clear(activeFielderAction, 0, activeFielderAction.Length);

最后两个参数是要清除的索引范围.

Answer 2

试试这个

Array.Clear(yourArray, 0, yourArray.Length);

Answer 3

以下代码有效：

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

namespace ConsoleApplication3
{
    class Program
    {
        static void Main(string[] args)
        {
            int[] activeFielderNumber = new int[10];
string[] activeFielderAction = new string[10];  

Array.Clear(activeFielderNumber, 0, activeFielderNumber.Length);
Array.Clear(activeFielderAction, 0, activeFielderAction.Length);
        }
    }
}
