1. 获取绝对文件路径
复制代码代码如下:
System.IO.Path.GetFullPath(string path)
string fileName = "myfile.ext";
string path1 = @"mydir";
string path2 = @"/mydir";
string fullPath;
fullPath = Path.GetFullPath(path1);
fullPath = Path.GetFullPath(fileName);
fullPath = Path.GetFullPath(path2);
2. 获取文件名字(得到指定路径内的文件名，不包括扩展名)
复制代码代码如下:
System.IO.Path.GetFileNameWithoutExtension(string path)
string fileName = @"C:/mydir/myfile.ext";
string path = @"C:/mydir/";
string result;
result = Path.GetFileNameWithoutExtension(fileName);
result = Path.GetFileName(path);
3.获得包含 path 目录信息的string 或者为空引用
复制代码代码如下:
System.IO.Path.GetDirectoryName(string path)
string fileName = @"C:/mydir/myfile.ext";
string path = @"C:/mydir/";
string rootPath = @"C:/";
string directoryName;
directoryName = Path.GetDirectoryName(fileName);
directoryName = Path.GetDirectoryName(path);
directoryName = Path.GetDirectoryName(rootPath);
4.合并两个路径字符串。
复制代码代码如下:
System.IO.Path.Combine(String path1, String path2)
