c# - 试图从 txt 文件填充文本框和 ListView

Question

我可以使用以下方法将文本框文本和 ListView 项目正确保存到 txt 文件中:

private void saveToolStripMenuItem_Click(object sender, EventArgs e)
    {
        if (saveFileDialog1.ShowDialog(this) == System.Windows.Forms.DialogResult.OK)
        {
            using (StreamWriter writer = new StreamWriter(saveFileDialog1.FileName))
            {
                //writer.WriteLine(accountText.Text);
                writer.WriteLine(accountText.Text);

                if (transactionList.Items.Count > 0)
                {
                    foreach (ListViewItem item in transactionList.Items)
                    {
                        StringBuilder newString = new StringBuilder();
                        foreach (ListViewItem.ListViewSubItem listSub in item.SubItems)
                        {
                            newString.Append(string.Format("{0}\t", listSub.Text));
                        }
                        writer.WriteLine(newString.ToString());
                    }
                    writer.WriteLine();
                }
            }
        }
    }

但是，我只能加载文本框，似乎无法填充 ListView 。到目前为止，这是我所拥有的:

private void openToolStripMenuItem_Click(object sender, EventArgs e)
    {
        if (openFileDialog1.ShowDialog(this) == System.Windows.Forms.DialogResult.OK)
        {
            using (StreamReader reader = new StreamReader(openFileDialog1.FileName))
            {
                accountText.Text = reader.ReadLine();

               if (transactionList.Items.Count == 0)
               {
                   foreach (ListViewItem item in transactionList.Items)
                   {
                       StringBuilder myString = new StringBuilder();
                       foreach (ListViewItem.ListViewSubItem listSub in item.SubItems)
                       {
                           myString.Append(string.Format("{0}\t", listSub.Text));
                       }
                       reader.Read();
                   }
                   reader.ReadToEnd();
               }
            }
        }
    }

如有任何提示，我们将不胜感激。

你只需要用'\t'字符分割字符串，它会返回string[]。然后只需将这些数组项添加到 ListView 即可。

string[] items = reader.ReadLine().Split('\t');
foreach (var item in items)
{
    var listViewItem = new ListViewItem(item);
    transactionList.Items.Add(listViewItem);    
}
