Provides information about and performs operations on symbolic links.

The class provides information about a symbolic link. It also allows basic symbolic link manipulation: Symbolic link creation with . Symbolic link deletion with . Constructor 1.0.5000.0 2.0.0.0 4.0.0.0 A containing the symbolic link to query.

Creates a new instance containing information about the symbolic link.

The argument is permitted to specify relative or absolute path information. Relative path information is interpreted as relative to the current working directory. To obtain the current working directory, see . It is valid to construct objects for symbolic links that do not exist or for files and directories. However, attempts to use the instance may generate s and other exception types. Use to see if exists, to ensure that is a symbolic link, and Use to ensure that the symbolic link target is valid. is . contains invalid characters; see . Property 1.0.5000.0 2.0.0.0 4.0.0.0 System.Obsolete("Use GetContents()") Mono.Unix.UnixFileSystemInfo

Gets the target of this symbolic link.

A reference containing information about the target of this symbolic link, or if : does not exist, or is not a symbolic link. The behavior will be changed in the future to generate an exception for either of the above error conditions, so current code needs to deal with both exceptions and a return value. will not be used by the Mono 1.2 release. Do not use this method, as it always creates a new instance -- no caching is performed, even though it's a property. Instead, use , This really should throw the same exceptions as instead of returning . The target may in turn be a symbolic link (nothing prevents symbolic links from referencing other symbolic links). To get the actual target, use , , or walk the symbolic link "chain":

UnixFileSystemInfo target = 
    new UnixSymbolicLinkInfo ("symlink").Contents;
while (target != null && 
        target.FileType == FileTypes.SymbolicLink) {
    target = ((UnixSymbolicLinkInfo) target).Contents;

Creates the symbolic link which refers to the symbolic link target .

Creates the symbolic link which refers to the target . The argument is permitted to specify relative or absolute path information. Relative path information is interpreted by the file system as relative to the symbolic link . Using instead of allows relative path information to be preserved within the symbolic link. The ln(1) command: ln -s target symlink Can be created using in two ways. First, it can be created using :

UnixFileInfo f = new UnixFileInfo ("target.ufi");
f.CreateSymbolicLink ("symlink.ufi");

Second, it can be created using :

UnixSymbolicLinkInfo s = 
    new UnixSymbolicLinkInfo ("symlink.usli");
s.CreateSymbolicLinkTo ("target.usli");

The links created by the above differ; in particular, the target of is the full path name of the target, while contains no extra information:

$ ls -lF symlink* | cut -c 39-
symlink -> target
symlink.ufi -> /full/path/to/target.ufi
symlink.usli -> target.usli

[] -or- The file would reside on a read-only file system.

[] -or- The new symbolic link cannot be created because there is no space left on the file system that will contain the symbolic link. [] -or- There are no free inodes on the file system on which the symbolic link is being created. [] -or- An I/O error occurred while making the directory entry or allocating the inode.
