Track changes for the two different text lines in Win c# application.

Hi,

Thanks for taking your time to read my query.

I need to have a tool or mechanisem which works similar to the Track Changes in MS word.

 If I pass the two text lines, it should show me the difference between the text.

Like add,Delete, Update on the text, I want to show it further on the RTF control with additional changes like if the text is deleted, I will show it strikethrough ..etc.

Please suggest a tool or dll or code, which I can be used for windows c# application.

Thanks and Regards

Naveen
