这里我的代码列出了一个字符串的所有排列

{
    public partial class Form1 : Form
    {
        private int n;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }
        private void textBox1_KeyDown(object sender, KeyEventArgs e)
        {
            string scrambledWord = textBox1.Text;

            if (e.KeyCode == Keys.Enter)
            {
                label4.Text = "";
                char[] arr = scrambledWord.ToCharArray();
                GetPer(arr);
            }
        }

        public void GetPer(char[] list)
        {
            int x = list.Length - 1;
            GetPer(list, 0, x);
        }

        private void GetPer(char[] list, int k, int m)
        {
            if (k == m)
            {
                Console.WriteLine(list);
                var text = new string(list);
                label4.Text = label4.Text + text + Environment.NewLine;

            }
            else
                for (int i = k; i <= m; i++)
                {
                    Swap(ref list[k], ref list[i]);
                    GetPer(list, k + 1, m);
                    Swap(ref list[k], ref list[i]);
                }
        }
        private void Swap(ref char a, ref char b)
        {
            if (a == b) return;

            var temp = a;
            a = b;
            b = temp;
        }

        private void label1_TextChanged(object sender, EventArgs e)
        {
            label4.Height = label4.Height + 10;
        }








    }
}

有人知道如何检查是否有任何排列是英语单词，并且代码在Visual Studio上打印英语单词吗？感谢You，You，You，You，You，You，You，You，You，You，You，You，
