Writing to a text file by trimming certain characters using C#?

Question

Here i am writing into a text file..I am searching for a key word Raiserror in a sql file and if that keyword exist i have to write that line..

It is writing like

LineNo : 66 :  raiserror ('Sequence number cannot be blank',16,1)

But i need to write only

 LineNo : 66 : Sequence number cannot be blank

Is this possible..If so how to trim.. Here is my code

while ((line = file.ReadLine()) != null)
{
    if (line.IndexOf("Raiseerror", StringComparison.CurrentCultureIgnoreCase) != -1)
    {
        dest.WriteLine("LineNo : " + counter.ToString() + " : " + "           " + line.TrimStart());
    }
    counter++;
}

file.BaseStream.Seek(0, SeekOrigin.Begin);
counter = 1;

Any Suggestion?

Try to use this

int errorIndex = line.IndexOf("Raiseerror", StringComparison.CurrentCultureIgnoreCase)
if (errorIndex  != -1)
{
  int start = line.IndexOf('\'', errorIndex) + 1;
  int finish = line.IndexOf('\'', start);
  dest.WriteLine("LineNo : " + counter.ToString() + " : " + "           " + line.Substring(start,finish - start));
}
