c# - How to read parts of an RTF file and keep formatting -

i asked create control reads in rtf file , display file in parts. problem running font styling seems stored @ higher level snippets pulling out. there way read snippets 1 file , keep formatting? using richtextbox in wpf.

this not perfect solution, works specific scenario. posting in case helps others later, still looking better solution. below work, has 2 pre-requisites:

• my delimiter has @ beginning , end of text
• my delimiter has different font or style has own distinct markup surrounding text

code:

private static ienumerable<string> getlistfromdelimitedtext(string text) {   var textsplit = text.split(new[] { "~~~~~~~~" }, stringsplitoptions.none);    var header = getheaderofrtf(textsplit);   var footer = getfooterofrtf(textsplit);   var listwithoutheaderandfooter =     textsplit.where((text, index) => index > 0 && index < textsplit.length - 1);   return getsnippetswithheaderandfooter(listwithoutheaderandfooter, header, footer); }  private static ienumerable<string> getsnippetswithheaderandfooter(ienumerable<string> snippetlist, string header, string footer) {   return snippetlist.select(text =>     {       var textwithoutleadingbracket = text.substring(text.indexof('}') + 1);       var cleanedtext = textwithoutleadingbracket.substring(0, textwithoutleadingbracket.lastindexof('{'));       return header + cleanedtext + footer;     }   ); }  private static string getfooterofrtf(ienumerable<string> textsplit) {   var lastsplit = textsplit.last();   return lastsplit.substring(lastsplit.indexof('}') + 1); }  private static string getheaderofrtf(ienumerable<string> textsplit) {   var firstsplit = textsplit.first();   return firstsplit.substring(0, firstsplit.lastindexof('{')); }
