    <p>This is fairly simple to do:</p> <pre><code>string path = "somepath"; String[] FileNames = Directory.GetFiles(path); </code></pre> <p>You can use LINQ to group the files by their name, without extension:</p> <pre><code>var fileGroups = from f in FileNames group f by Path.GetFileNameWithoutExtension(f) into g select new { Name = g.Key, FileNames = g }; // each group will have files with the // same name and different extensions foreach (var g in fileGroups) { // initialize zip file foreach (var fname in g.FileNames) { // add fname to zip } // close zip file } </code></pre> <h2>Update</h2> <p>The task isn't too much more difficult if you don't have LINQ. First, you want to sort the files:</p> <pre><code>Array.Sort(FileNames); </code></pre> <p>Now, you have a list of files, sorted by file name. So you'll have, for example:</p> <pre><code>file1.ext1 file1.ext2 file1.ext3 file2.ext1 file2.ext2 etc... </code></pre> <p>Then just go through the list, adding files with the same base name to zip files, as below. Note that I don't know how you're creating your zip files, so I just made up a simple <code>ZipFile</code> class. You'll of course need to replace that with whatever you're using.</p> <pre><code>string lastFileName = string.Empty; string zipFileName = null; ZipFile zipFile = null; for (int i = 0; i &lt; FileNames.Length; ++i) { string baseFileName = Path.GetFileNameWithoutExtension(FileNames[i]); if (baseFileName != lastFileName) { // end of zip file if (zipFile != null) { // close zip file ZipFile.Close(); } // create new zip file zipFileName = baseFileName + ".zip"; zipFile = new ZipFile(zipFileName); lastFileName = baseFileName; } // add this file to the zip zipFile.Add(FileNames[i]); } // be sure to close the last zip file if (zipFile != null) { zipFile.Close(); } </code></pre> <p>I don't know if the Compact Framework has the <code>Path.GetFileNameWithoutExtension</code> method. If not, then you can get the name without extension by:</p> <pre><code>string filename = @"c:\dir\subdir\file.ext"; int dotPos = filename.LastIndexOf('.'); int slashPos = filename.LastIndexOf('\\'); string ext; string name; int start = (slashPos == -1) ? 0 : slashPos+1; int length; if (dotPos == -1 || dotPos &lt; slashPos) length = filename.Length - start; else length = dotPos - start; string nameWithoutExtension = filename.Substring(start, length); </code></pre>

    1. COthis is the most elegant solution.but unfortunately,I am developing on .Net compact framework 2.0. I wont be able to use LINQ in this environment.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
