Method pathname.getDirectory

Overload

Removes filename part from path. By default also removes separator ('\\' or '/') if it is not after drive name (eg "C:").

public static string getDirectory(string path, bool withSeparator = false)

Parameters

path (string)

Path or filename. Can be null.

withSeparator (bool)

Don't remove separator character(s) ('\\' or '/'). See examples.

Returns

string

Returns "" if the string is a filename. Returns null if the string is null or a root (like @"C:\" or "C:" or @"\\server\share" or "http:").

Remarks

Similar to System.IO.Path.GetDirectoryName. Some differences: skips '\\' or '/' at the end (eg from @"C:\A\B\" gets @"C:\A", not @"C:\A\B"); does not replace '/' with '\\'.

Parses raw string. You may want to pathname.normalize it at first.

Supports separators '\\' and '/'. Also supports URL and shell parsing names like @"::{CLSID-1}\0\::{CLSID-2}".

Examples:

path	result
`@"C:\A\B\file.txt"`	`@"C:\A\B"`
`"file.txt"`	`""`
`@"C:\A\B\"`	`@"C:\A"`
`@"C:\A\/B\/"`	`@"C:\A"`
`@"C:\"`	`null`
`@"\\network\share"`	`null`
`"http:"`	`null`
`@"C:\aa\file.txt:alt.stream"`	`"C:\aa"`
`"http://a.b.c"`	`"http:"`
`"::{A}\::{B}"`	`"::{A}"`
`""`	`""`
`null`	`null`

Examples when withSeparator true:

path	result
`@"C:\A\B"`	`@"C:\A\"` (not `@"C:\A"`)
`"http://x.y"`	`"http://"` (not `"http:"`)
