Aspx to Razor syntax converter? [closed]

Question

I have a considerable amount of ASPX and ASCX files writed in C# for MVC and I would like to convert them to the new Razor syntax.

Any body knows about some utility that makes this job faster?

Answer 1

I've written a small piece of code that makes the conversion. I think it could be useful to somebody else. I've learned a lot about regex's balancing goup definitions on the way.

    public static class RazorConversor {     public static void ConvertAll(string directory)     {         string[] array = Directory.GetFiles(directory, "*.aspx", SearchOption.AllDirectories).Concat(                          Directory.GetFiles(directory, "*.ascx", SearchOption.AllDirectories)).ToArray();          foreach (var fileName in array)         {             string aspxCode = File.ReadAllText(fileName);             string razorCode = ConvertToRazor(aspxCode);             File.WriteAllText(fileName, razorCode); //rename manually to update .csproj & source control         }     }      static readonly string[] DefaultNamespaces = new string[]     {         "System.Web.Helpers",          "System.Web.Mvc",         "System.Web.Mvc.Ajax",         "System.Web.Mvc.Html",         "System.Web.Routing",         "System.Web.WebPages",     };      public static string ConvertToRazor(string aspxCode)     {         return ConvertToRazor(aspxCode, DefaultNamespaces);      }      public static string ConvertToRazor(string aspxCode, string[] defaultNamespaces)     {         //namespaces         string text2 = Regex.Replace(aspxCode, @"<%@\s+Import Namespace=""(?<ns>.*?)""\s+%>",             m => defaultNamespaces.Contains(m.Groups["ns"].Value) ? null : "@using " + m.Groups["ns"].Value);          //headers         string text3 = Regex.Replace(text2, @"<%@\s(?<dir>.*?)%>", m =>  "@{ " + m.Groups["dir"].Value + "}"); // Preserves headers          //expressions          string text4 = Regex.Replace(text3, @"<%[=:](?<expr>.*?)%>", m =>         {             string expr = m.Groups["expr"].Value.Trim();             string cleanExpr = Regex.Replace(expr, @"(""(\\""|[^""])*"")|(@""([^""]|"""")*"")|(\([^\(\)]*(((?'Open'\()[^\(\)]*)+((?'Close-Open'\))[^\(\)]*)+)*\))", m2 => "");             return cleanExpr.Contains(' ') ? "@(" + expr + ")" : "@" + expr;         }, RegexOptions.Singleline);          //code blocks         string text5 = Regex.Replace(text4, @"<%(?<code>.*?)%>", m =>         {             string code = m.Groups["code"].Value.Trim();              Dictionary<string, string> stringLiterals = new Dictionary<string,string>();              code = Regex.Replace(code, @"(""(\\""|[^""])*"")|(@""([^""]|"""")*"")", m2 =>             {                 string key = "<$" + stringLiterals.Count + "$>";                 stringLiterals.Add(key, m2.Value);                 return key;             });               string result = Regex.Replace(code,                  @"((?<blockHeader>(else|(for|switch|foreach|using|while|if)\s*\([^\(\)]*(((?'Open'\()[^\(\)]*)+((?'Close-Open'\))[^\(\)]*)+)*\))\s*)" +                  @"((?<fullBlock>{[^{}]*(((?'OpenCurly'{)[^{}]*)+((?'CloseCurly-OpenCurly'})[^{}]*)+)*})|(?<openblock>{.*))|" +                  @"(?<text>((?!({|}|\s)(for|switch|foreach|using|while|if|else)(\s|{|\()).)+))",                 m2 =>                 {                     if(m2.Value.Trim().Length == 0 || m2.Value.StartsWith("else")|| m2.Value.StartsWith("}"))                         return m2.Value;                      if(m2.Groups["text"].Success)                         return "@{ " + m2.Value.Trim() + "}\r\n";                       return "@" + m2.Value;                  }, RegexOptions.ExplicitCapture | RegexOptions.Singleline);              result = Regex.Replace(result, @"<\$\d+\$>",                  m2 => stringLiterals[m2.Value]);              return result;         }, RegexOptions.Singleline);          return text5;      } }

Try this

http://razorconverter.codeplex.com/

It is a codeplex project that I wrote that automates Olma code with some refinements. There is also an exe download that requires .Net 2.0 I think and you can just drop it into your view folder and it converts everything automatically.
