Am working on creating a simple text editor that also supports image and using richtextbox (winforms) for the same. How to read the content of the richtextbox line by line (that also includes image) and export it to a datatable or a datagrid(from where i will export it to excel). i am able to read the lines if the lines are text. The problem is how to check if a particular line contains image and export it? When i use richtextbox1.rtf.contains('\pict..')it searches the entire text box , how to make it read only the current line. Please help. Thanks in advance.

Create a loop that goes line by line or isolate the current line somehow and do the search.

You said you searched whole RTF (with rtf.contains('\pict..') ). So...why can't you isolate current line? Once you get the line, you also get if there is a picture in it. Or do I misunderstand something?

ya , i am reading the richtextbox line by line,but i dont know how to search for a picture in a specific line, that is my prob. Couldnt use this "rtf.contains('\pict')" for a specific line.

you don't use rtf.contains()., but line.contains...if you're reading line by line simply ask the current line if it contains pict text
line.contains("\pict") or line.IndexOf("\pict") > -1

You could write an extension method that extract formatted lines (or paragraphs)
a line ends in /line
a paragraph ends in /par

Refer to the rtf specifications for details.
