Using Dispatcher with thread - asp.net-mvc-4

Question

I have a list of rtf strings that are needed to convert to html. I am using a richtextbox control to convert rtf to html. My problem is this
The solution should also work but how do i implement this solution in my code?
public string ConvertRtfToHtml(string rtfText)
{
try
{
var thread = new Thread(ConvertRtfInSTAThread);
var threadData = new ConvertRtfThreadData { RtfText = rtfText };
thread.SetApartmentState(ApartmentState.STA);
thread.Start(threadData);
try
{
thread.Join();
}
catch(ThreadStateException e){
logger.Error("ThreadStateException " + e.Message);
}
catch (ThreadInterruptedException e) {
logger.Error("ThreadInterruptedException " + e.Message);
}
return threadData.HtmlText;
}
catch (Exception e){
logger.Error("ConvertRtfToHtml: " + e.InnerException.Message);
return "Error";
}
}
private void ConvertRtfInSTAThread(object rtf)
{
MarkupConverter.MarkupConverter markupConverter = new MarkupConverter.MarkupConverter();
var threadData = rtf as ConvertRtfThreadData;
try
{
threadData.HtmlText = markupConverter.ConvertRtfToHtml(threadData.RtfText);
}
catch(Exception e){
logger.Error("ConvertRtfInSTAThread: " + e.Message);
}
}
this markupconverter.convertrtftohtml uses richtextbox control.
Where do i fit the Dispatcher in above code?
Dispatcher dispatcher = Dispatcher.CurrentDispatcher;
dispatcher.BeginInvokeShutdown(DispatcherPriority.Normal);
Dispatcher.Run();

Answer 1

I used it as follows
private void ConvertRtfInSTAThread(object rtf)
{
MarkupConverter.MarkupConverter markupConverter = new MarkupConverter.MarkupConverter();
var threadData = rtf as ConvertRtfThreadData;
try
{
threadData.HtmlText = markupConverter.ConvertRtfToHtml(threadData.RtfText);
Dispatcher dispatcher = Dispatcher.CurrentDispatcher;
dispatcher.BeginInvokeShutdown(DispatcherPriority.Normal);
Dispatcher.Run();
}
catch(Exception e){
logger.Error("ConvertRtfInSTAThread: " + e.Message);
}
}
