当我尝试用数组填充代码时，代码无法识别Listbox

Question

您好我正在尝试用数组填充一个简单的ListBox。我的代码;它会抛出此错误

错误1当前上下文中不存在名称“myArrayList”

public class Class1
{
    public void FillArray()
    {
        int min = 1;
        int max = 1000;
        int[] testArray = new int[1000];
        Random randNumber = new Random();
        for (int i = 1; i < testArray.Length; i++)
        {
            testArray[i] = randNumber.Next(min, max);  
        }
        foreach (int value in testArray)
        {
            myArrayList.ItemSource = testArray;
        }

    }
}
