  C# Method Regex implementation and Razor

  Feb 28, 2012 09:48 PM|LINK

  Yesterday,  I had someone help me with Regex in a single razor model. It didnt quite fit my needs. I needed more regex replaces to be done and I do not know how to chain them unles  i do multiple IFs

  I found this awesome example. a straight forward method to part a status messages in twitter.

  How would I implement this in my razor view model?  Any tips would be appreciated.

  http://www.diaryofaninja.com/blog/2010/03/10/twitterify-your-strings-using-c-regex

  public static String AddWebAndTwitterLinks(string input)
  {
      string strWebLinks = @"(^|[\n ])([\w]+?://[\w]+[^ \n\r\t< ]*)";
      string strWebLinksWWW = @"(^|[\n ])((www|ftp)\.[^ \t\n\r< ]*)";
      string strTwitterNames = @"@(\w+)";
      string strTwitterTags = @"#(\w+)";
      input = Regex.Replace(input, strWebLinks, 
          " <a href=\"$2\" target=\"_blank\">$2</a>");
      input = Regex.Replace(input, strWebLinksWWW, 
          " <a href=\"http://$2\" target=\"_blank\">$2</a>");
      input = Regex.Replace(input, strTwitterNames, 
          "<a href=\"http://www.twitter.com/$1\" target=\"_blank\">@$1</a>");
      input = Regex.Replace(input, strTwitterTags, 
          "<a href=\"http://search.twitter.com/search?q=$1\" target=\"_blank\">#$1</a>");
  
      return input;
  }
  
  Here is my   razor view,  nothing complex.  I use my css to style the message.   I need to pass the model as the string input.
  
  

  @model IEnumerable<MvcApplication1.Models.TweetViewModel>
  @using System.Text.RegularExpressions;
   
  @{
      ViewBag.Title = "Index";
   
  }
  <h2>
      Index</h2>
   
   
  <p>
      @Html.ActionLink("Create New", "Create")
   
  </p>
  @foreach (var item in Model)
  {
      @Html.Hidden(item.StatusId)
      <ol>
          <li class="stbody">
              <div class="stimg">
                  <img src=@Url.Content(item.ImageUrl) alt="@item.ScreenName" />
              </div>
              <div class="stnames">
                  @item.User
              </div>
              <div class="stnicknames">
                  <div id="Screenname">
                      @Regex.Replace(item.ScreenName, @"/\B\@([\w\-]+)/gim", "<a href=\"http://twitter.com/$2\">$1</a>", RegexOptions.IgnoreCase)
                   
                  </div>
              </div>
              <div class="sttext">
           
                  @Regex.Replace(item.Tweet, @"((www\.|(http|https|ftp|news|file)+\:\/\/)[&#95;.a-z0-9-]+\.[a-z0-9\/&#95;:@=.+?,##%&~-]*[^.|\'|\# |!|\(|?|,| |>|<|;|\)])", "<a href=\"$1\" title=\"Click to open in a new window or tab\" target=\"&#95;blank\">$1</a>", RegexOptions.IgnoreCase)
          
               
              </div>
          </li>
      </ol> 
  }

  I found my answer I hope its a good practice

  In the linq query  I passed the static method into the list result

  Tweet = HomeController.AddWebAndTwitterLinks(tweet.Text),
  
  on the view  I called  @mvchtmlstring(item.tweet)
