  Regex to replace spaces with underscores

  May 17, 2013 06:08 PM|John Merchant|LINK

  The intention:

  Dynamically generate collapsible content from a directory with subdirectories containing images.

  The problem:

  The generated href from the directory names occasionally contain spaces. The same directory name var is used to generate IDs for the matching <div>. the ID name cannot contain spaces. I would like to replace the spaces with a usable character to create a valid ID name.

  The question:

  Where and how would I code to replace the spaces with underscores in @dir.Name, without renaming the original directory? I believe the answer lies in the use of @Regex.Replace but do not know the how/where part.

  Can anyone assist me or point me to a good reference for this situation? I'm fairly new to programming.

  Thank you.

  The code:

  @{

      var photofolderpath = Server.MapPath("~/Photos");
      var directoryInfo = new DirectoryInfo(photofolderpath);
      var photodirectories = directoryInfo.GetDirectories("*.", SearchOption.AllDirectories);

  }

  <div class="accordion" id="gallery" data-toggle="modal-gallery" data-target="#modal-gallery">
      @foreach(var dir in photodirectories){
          <div class="accordion-group">
              <div class="accordion-heading">
                  <a class="accordion-toggle" data-toggle="collapse" data-parent="#gallery" href="#@dir.Name">
                      <h4><i class="icon-plus-sign"></i> @dir.Name</h4>
                  </a>
              </div>
              <div id="@dir.Name" class="accordion-body collapse">
                  <div class="accordion-inner">
                      <ul style="list-style-type: none;">
                          @foreach(var file in dir.GetFiles()){
                              <li>
                                  <a href="~/Photos/@dir.Name/@file.Name" title="@file.Name" class="polaroid" alt="@file.Name" data-gallery="gallery">@file.Name</a>
                              </li>
                              }
                      </ul>
                  </div>
              </div>
              </div>
          }
  </div>
