I have a text file containing text in the form,

all the world ends in 10 days 2
sample line1
sample line 2
roger federer wins the tournament 3
sample line 1
sample line 2
sample line 3


In the about example, there are two types of lines,
1. starts without blank space
2. starts with blank space

all the world ends in 10 days 2
the last digit, i.e 2 should be extracted from each line which starts without a blank space (expedtedNoOfLines)
the number of lines which starts with a blank space should match expedtedNoOfLines

while((line = sr.ReadLine()) !=null)
{
if(!line.startswith(" "))
{
expectedLines = line.Substring(line.Length-1, 1);
}
else
{
actualLinesCount++;
}

if(expectedLines != actualLinesCount)
richTextEditor.SelectionColor = Color.Red;
else
richTextEditor.SelectionColor = Color.Black;

richTextEditor.text = line;
richTextEditor.text = System.Environment.NewLine;
}

The above code is not working.....any help?

You seem to be assigning Environment.Newline to the rich text box control right after you assign the line to it:

richTextEditor.text = line;
richTextEditor.text = System.Environment.NewLine;

Not sure if this is intentional, probably not. What you're probably looking for is:

richTextEditor.text = line;
richTextEditor.text += System.Environment.NewLine;

or just

richTextEditor.text = (line + System.Environment.NewLine);
