短处理路径名

目前我的文件路径是

 @"S:'Temporary Shared Space'Project'Boyscout3'Data'full_pack.txt"

我希望它只是"full_pack.txt"。

我在底部尝试了这个代码，但它似乎不适合我:

如果有人能帮忙的话，我会很感激的。

string fileName =@"S:'Temporary Shared Space'Project'Boyscout'Data'full_pack.txt";
string path = "full_pack.txt";
string result;
result = System.IO.Path.GetFileName(fileName);
Console.WriteLine("GetFileName('{0}') returns '{1}'", fileName, result);
result = System.IO.Path.GetFileName(path);
Console.WriteLine("GetFileName('{0}') returns '{1}'", path, result);
//filename shorter for den1
string fileName1 =@"S:'Temporary Shared Space'Project'Boyscout3'Data'den1.txt";
string path1 = "den1.txt";
string result1;
result1 = System.IO.Path.GetFileName(fileName1);
Console.WriteLine("GetFileName('{0}') returns '{1}'", fileName1, result1);
result1 = System.IO.Path.GetFileName(path1);
Console.WriteLine("GetFileName('{0}') returns '{1}'", path1, result1);
//Making a list for full_pack
List<string> listFullPack = new List<string>();
string line;
StreamReader sr = new StreamReader("full_pack.txt");//this is where things don't work. 
while ((line = sr.ReadLine()) != null)////When the full address is in, the code works, 
{                            //but when I replace it with full_pack.txt, 
    listFullPack.Add(line); //it can't find the file.
}
sr.Close();
