Returns the absolute path for the specified path string.
Assembly: System.IO (in System.IO.dll)
The absolute path includes all information required to locate a file or directory on a system.
The file or directory specified by path is not required to exist. For example, if c:\temp\newdir is the current directory, calling GetFullPath on a file name such as test.txt returns c:\temp\newdir\test.txt. The file need not exist.
However, if path does exist, the caller must have permission to obtain path information for path. Note that unlike most members of the Path class, this method accesses the file system.
This method uses current directory and current volume information to fully qualify path. If you specify a file name only in path, GetFullPath returns the fully qualified path of the current directory.
If you pass in a short file name, it is expanded to a long file name.
If a path contains no significant characters it is invalid unless it contains one or more "." characters followed by any number of spaces, then it will be parsed as either "." or "..".
- Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see dd66cd4c-b087-415f-9c3e-94e3a1835f74.
