C#如何在一个文本文件中写多行? [英] C# how to write multiple lines in a text file?

问题描述

我试图按下一个按钮，该按钮将从textbox4和textbox5中获取文本，以将其写入文本文件.但是，当我再次按它向文本文件中添加新信息时，它只是将旧文本替换为新文本.每次按下按钮时，如何在第一行下面写一行?

I am trying to press a button that takes the text from textbox4 and textbox5 to write it to a text file. BUT when I press it again to add new info to the text file it just replaces the old text in with the new. How do I get it to write another line below the first one each time I press the button?

这是我到目前为止的代码

This is the code I have so far

    private void button5_Click(object sender, EventArgs e)
    {
        try
        {
            xuidspath = @"c:\xuids.txt";
            ListViewItem lvi = new ListViewItem();
            lvi.Text = textBox4.Text;
            lvi.SubItems.Add(textBox5.Text);
            listXuid.Items.Add(lvi);
            TextWriter xuids = new StreamWriter(xuidspath);
            xuids.WriteLine(textBox4.Text + "-" + textBox5.Text);
            textBox5.Clear();
            textBox4.Clear();
            xuids.Close();
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message, "Error!", MessageBoxButtons.OK, MessageBoxIcon.Error);
        }
    }

有什么想法吗?

推荐答案

打开文件进行追加.

FileStream xuids = new FileStream(xuidspath, FileMode.Append);
