POCreate paged tiff file based on file prefixes in a directory using C#

Body
copied!<p>No need for the tiff file creation as I already have it. I'm just trying to figure out the algorithm to create the files based on pre-fixes of the file names in the directory.</p> <p>I have a folder called <code>C:\Policy Images</code>. in this folder are pictures. the names of the pictures are as follows:</p> <p>Policy Number / Picture Name as such:</p> <pre><code>AAAAAAA-Pic1 AAAAAAA-Pic2 AAAAAAA-Pic3 ZZZZZZZ-Pic1 ZZZZZZZ-Pic2 FFFFFFF-Pic1 ... </code></pre> <p>When creating the tiff files, I need to create 1 tiff per policy number. based on the above, for example, Id have this:</p> <pre><code> AAAAAAA-1 (containing 3 pages in this tiff file) ZZZZZZZ-1 (containing 2 pages in this tiff file) FFFFFFF-1 (containing 1 page in this tiff file) </code></pre> <p>The problem with my code below is that it is creating a tiff for all files in the directory and not based on policy number. the part of the code that says "<code>foreach (string s in AllFilesInDirectory)</code>" needs to be really <code>foreach</code> (string s in policy 1/policy 2/policy 3, etc).</p> <p>how exactly would I do that? im beating my head against a wall right now.</p> <p>this is what I have so far:</p> <pre><code>string[] AllFilesInDirectory = Directory.GetFiles(SelectedDirectory); //get the codec for tiff files ImageCodecInfo info = null; foreach (ImageCodecInfo ice in ImageCodecInfo.GetImageEncoders()) if (ice.MimeType == "image/tiff") info = ice; //use the save encoder Encoder enc = Encoder.SaveFlag; EncoderParameters ep = new EncoderParameters(1); ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.MultiFrame); Bitmap pages = null; int frame = 0; foreach (string s in AllFilesInDirectory) { if (frame == 0) { pages = (Bitmap)Image.FromFile(s); //save the first frame pages.Save(AppVars.MergedPolicyImagesFolder + "\\" + PolicyNumber + ".tiff", info, ep); PolicyNumber++; } else { //save the intermediate frames ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.FrameDimensionPage); Bitmap bm = (Bitmap)Image.FromFile(s); pages.SaveAdd(bm, ep); } if (frame == AllFilesInDirectory.Length - 1) { //flush and close. ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.Flush); pages.SaveAdd(ep); } frame++; } </code></pre>
