            InitializeComponent();

            for (int i = 0; i < ListsExtractions.text1.Count; i++)
            {
                richTextBox1.Text = ListsExtractions.text1[i];
            }

Answer 1

更改此

for (int i = 0; i < ListsExtractions.text1.Count; i++)
        {
            richTextBox1.Text = ListsExtractions.text1[i];
        }

到这个

richTextBox1.Text = String.Join(Environment.NewLine, ListsExtractions.text1 );

我认为你是两次调用它，从构造函数移动到你的代码的加载事件：

   using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;
    using System.Windows.Forms;

    namespace ScrollLabelTest
    {
        public partial class DisplayLockedThreads : Form
        {
            public DisplayLockedThreads()
            {
                InitializeComponent();

            }

            private void DisplayLockedThreads_Load(object sender, EventArgs e)
            {
               richTextBox1.Text = String.Join(Environment.NewLine, ListsExtractions.text1 );    
            }
        }
    }
