namespace StopwatchTimer
{
    public partial class Form1 : Form
    {
        public string settingsPath = "Settings";

        private string settingsFileName = "settings.txt";
        private static readonly Stopwatch watch = new Stopwatch();
        private long diff = 0, previousTicks = 0, ticksDisplayed = 0;

        public Form1()
        {
            InitializeComponent();

            richTextBox1.TabStop = false;
            richTextBox1.ReadOnly = true;
            richTextBox1.BackColor = Color.White;
            richTextBox1.Cursor = Cursors.Arrow;
            richTextBox1.Enter += RichTextBox1_Enter;

            settingsPath = Path.Combine(Path.GetDirectoryName(Application.LocalUserAppDataPath), settingsPath);
            if (!Directory.Exists(settingsPath))
                Directory.CreateDirectory(settingsPath);

            settingsFileName = Path.Combine(settingsPath, settingsFileName);
            if (!File.Exists(settingsFileName))
                File.Create(settingsFileName);

            string[] settings =  File.ReadAllText(settingsFileName).Split(',');
            if(settings.Length > 0)
            {

            }
    }       radioButton1.Checked = true;
}

我还没有写入文本文件。例如，我想将radioButton1和radioButton2状态写到文本文件中的其他位置，然后在运行应用程序时读回状态。

所以我将Split与'，'一起使用，但是如何检查回读时的值是属于radioButton1还是radioButton2还是属于textBox或button1？

您可以使用内置的winforms设置：

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
  Properties.Settings.Default.Username = txtUsername.Text;
  Properties.Settings.Default.Password = txtPassword.Text;
  Properties.Settings.Default.Save();
}

C# Setting load and save

如何将设置保存到文本文件并读回？
