namespace PostingQueueMonitoring_V2
{
    public partial class Helper : Form
    {
        public Helper()
        {
            InitializeComponent();
        }
        private void button1_Click(object sender, EventArgs e)
        {  
            if (String.IsNullOrEmpty(input_richTextBox1.Text.Trim()))
            {
                MessageBox.Show("Please input text...");
                return;
            }
            string[] myText = new string[] {input_richTextBox1.Text};
            foreach (string element in myText)
            {
                output_richTextBox2.Text = element;
                System.Console.WriteLine(output_richTextBox2.Text);
            }
            System.Console.WriteLine();
            //output_richTextBox2.Rtf = input_richTextBox1.Rtf;
        }
        private void Helper_Resize(object sender, EventArgs e)
        {
            this.MinimumSize = new Size(736, 466);
            this.MaximumSize = new Size(736, 466);
        }
    }
}

如何更新将格式化input_richTextBox1和output_richTextBox2中显示的文本的代码。在下面的例子。

input_richTextBox1:苹果' n班纳' n椰子' n榴梿' n橙色
output_richTextBox2的预期结果('苹果',"班纳","椰子","榴莲","橙色")

请尝试一下。

        private void button1_Click(object sender, EventArgs e)
    {
        if (String.IsNullOrEmpty(richTextBox1.Text.Trim()))
        {
            MessageBox.Show("Please input text...");
            return;
        }
        var textValues = richTextBox1.Text.Split(''n').Select(txt => $"'{txt}'");
        var concatValues = string.Join(",", textValues);
        richTextBox2.Text = concatValues;
        System.Console.WriteLine();
    }
