Question

这是我的代码。我正在尝试从存储在音乐文件夹中的.txt文件读取数据。但是我遇到了一些错误， System.NotSupportedException。不支持指定路径的格式。

请帮助...........

string path = @"Music:\streamfile.txt";

using (StreamReader sr = File.OpenText(path))
{
    String s = "";

    while ((s = sr.ReadLine()) != null)
    {
        Console.WriteLine(s);
    }
}
Console.ReadLine();

您可以尝试Environment.GetFolderPath

//if you want windows common music folder ex:C:\Users\Public\Music\streamfile.txt
var CommonMusicPath = Environment.GetFolderPath(Environment.SpecialFolder.CommonMusic) + @"\streamfile.txt"; 
//if you want windows user music folder ex:C:\Users\username\Music\streamfile.txt
var MyUserMusicPath = Environment.GetFolderPath(Environment.SpecialFolder.MyMusic) + @"\streamfile.txt"; 
using (StreamReader sr = File.OpenText(MyUserMusicPath))
{
    String s = "";

    while ((s = sr.ReadLine()) != null)
    {
        Console.WriteLine(s);
    }
}
Console.ReadLine();

Answer 2

在某处有一个带有“特殊”文件夹的列表，但是您可以自己构建它：

  string path = Path.Combine(Environment.GetEnvironmentVariable("USERPROFILE"),
           "Music", "streamfile.txt");

我无法使用c＃
