Anonymous User217403-Nov-2014

im doing some experiment on how can i get specific index of string in richTextBox Control .

scenario: I need to find lastIndex of #> but doesnt match with ##>

reason (2) ## will block #

heres what i started for now:

string text = richTextBox1.Text;int lastIndexOffragment = text.LastIndexOf('#>');

Q: How can i find the real last Index of #> with validation thats its not ##>

I know this is a very ugly method but, i think this will be very easy and not complecated.

str ="your string";int iLastIndex = str.Replace("##>","^^>").LastIndexOf("#>");

you can use any character instead of ^.
