nant: Can I extract the last directory in a path?

In Nant, I would like to be able to extract the last name of the directory in a path.
For example, we have the path 'c:\my_proj\source\test.my_dll\'

I would like to pass in that path and extract 'test.my_dll'

Is there a way to easily do this?

Expanding on Steve K:

<script language="C#" prefix="path" >
    <code>
        <![CDATA[
          [Function("get-dir-name")]
          public static string GetDirName(string path) {
              return System.IO.Path.GetFileName(path);
          }
        ]]>
    </code>
 </script>

<target name="build">
    <foreach item="Folder" in="." property="path">
        <echo message="${path::get-dir-name(path)}" />
    </foreach>
</target>

You can actually do it with existing NAnt string functions. Just a bit ugly...

${string::substring(path, string::last-index-of(path, '\') + 1, string::get-length(path) - string::last-index-of(path, '\') - 1)}

You may want to try the new function added to nant 0.93 (still in the nightly builds though) -

directory::get-name(path)

This would return the name of the directory mentioned in the path.

Refer to nant help

It is possible to find the parent directory of your path and then use string replace to find the folder you're looking for:

<property name="some.dir" value="c:\my_proj\source\test.my_dll" />
<property name="some.dir.parent" value="${directory::get-parent-directory(some.dir)}" />
<property name="directory" value="${string::replace(some.dir, some.dir.parent + '\', '') }" />

No. You'll need to write a custom task for something like that.

See the script task. You can write custom code in C# or whatever, and return a value that you can assign to a property.
