C#获取路径中文件名、目录、扩展名等相关信息代码

直接上代码

string path = “C:\\dir1\\dir2\\foo.txt”;

string str = “GetFullPath：” + Path.GetFullPath(path) + “\r\n”;

str += “GetDirectoryName：” + Path.GetDirectoryName(path) + “\r\n”;

str += “GetFileName：” + Path.GetFileName(path) + “\r\n”;

str += “GetFileNameWithoutExtension：” + Path.GetFileNameWithoutExtension(path) + “\r\n”;

str += “GetExtension：” + Path.GetExtension(path) + “\r\n”;

str += “GetPathRoot：” + Path.GetPathRoot(path) + “\r\n”;

MessageBox.Show(str);

输出的结果是：

GetFullPath：C:\dir1\dir2\foo.txt

GetDirectoryName：C:\dir1\dir2

GetFileName：foo.txt

GetFileNameWithoutExtension：foo

GetExtension：.txt

GetPathRoot：C:\
