正如你所看到的那样，它有一个歌曲名称，旁边是歌曲的路径 

as you can see form the example it has the song name and next to it the path of the song 

是否有办法搜索整个文件获取歌曲名称。 。并改变每首歌曲路径的路径，以便更好地理解

所以我希望我的程序能够获得列出的每首歌曲的路径，然后保存路径，然后再用新路径重新编写文件，因为该程序存储了用户名elfenliedtopfan5。这里的女巫不会在其他电脑上相同所以有没有办法解析
虽然每个歌曲的名称和路径，并将路径存储在文本文件或类似的东西，然后当你加载程序时它会保持当您在taget pc上加载它时，它将保存路径以更新路径

将用户名更改为pc的用户名是可能的或改变整个路径。

推荐答案

Hello elfenliedtopfan2，

Hello elfenliedtopfan2,

如果要解析文本文件，专业的方法是保存数据作为XML格式或Json格式。至于上面的例子，它没有统一的格式，可能会导致一系列不匹配问题。我强烈建议你
将数据保存为XML格式，并通过XmlDocument对象解析文件。一个简单的例子如下所示。

If you want to parse the text file, the professional way is that save the data as XML format or Json format. As for the above example, it doesn't have a uniform format and maybe it will cause a series of mismatch issues. I strongly recommend that you save data as XML format and parse the file by XmlDocument object. A simple example as below.

对于给定的XML文件。

For a given XML file.

<?xml version="1.0" encoding="utf-8" ?>
<Songs>
  <Song>
    <Name>Name1</Name>
    <Singer>Singer1</Singer>
    <Path>Path1</Path>
  </Song>
  <Song>
    <Name>Name2</Name>
    <Singer>Singer2</Singer>
    <Path>Path2</Path>
  </Song>
</Songs>

解析如下。

 XmlDocument doc = new XmlDocument();
            doc.Load("../../XMLFile1.xml");

            foreach (XmlNode node in doc.DocumentElement.ChildNodes)
            {
                foreach (XmlNode no in node) {
                    Console.WriteLine( no.InnerText);
                }
                Console.WriteLine("---------------");
            }

关于第二个问题，可以通过以下代码访问更新的路径，具体取决于不同的PC。

As for your second question, the updated path depend on different PC could be accessed by below code.

 string ss1 = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);

Or

string ss2= Environment.GetFolderPath(Environment.SpecialFolder.UserProfile);

致以最诚挚的问候，
