如何将string []行更改为输出字符串？

How do I change string[] lines into output string?

protected void Button1_Click(object sender, EventArgs e)
        {
            string data1 = TextBox1.Text;
            using (System.IO.FileStream fs = new System.IO.FileStream(Server.MapPath("~/data.txt"), System.IO.FileMode.Append, System.IO.FileAccess.Write, System.IO.FileShare.Read, 8, System.IO.FileOptions.None))
            {
                byte[] data = System.Text.Encoding.ASCII.GetBytes(data1);
                fs.Write(data, 0, data.Length);
                fs.Flush();
                fs.Close();
            }
        }

        protected void Button2_Click(object sender, EventArgs e)
        {
            string[] lines = File.ReadAllLines(Server.MapPath("~/data.txt"));
            string stglines
            ???change string[] to strlines
            TextBox2.Text = strline.ToString();
        }

推荐答案

为什么不使用 ReadAllText（String）代替？

您需要做的就是使用 StringBuilder类 [ ^ ]。

All you need to do is to loop through the collection of lines using StringBuilder class[^].

StringBuilder sb = new StringBuilder();
foreach (string str in lines)
{
sb.Append(str);
}
//finally:
TexBox2.Text  = sb.ToString();

但是，就个人而言，我建议使用解决方案1.





String.Concat（）方法 [ ^ ]连接指定String数组的元素。



谢谢PIEBALDconsult。我忘了这个方法！

But, personally, i'd suggest to use solution 1.


String.Concat() method[^] concatenates the elements of a specified String array.

Thank you, PIEBALDconsult. I forgot about that method!
