    Parsing of text

    Hi all,
    i am trying to read the route table in the application. I want to seperate the result into multiple files.
    Code:
     static void Main(string[] args)
            {
              
                
    
                System.Diagnostics.Process.Start("cmd.exe", @"/c route print > d:\test.txt");
                        
            }
    On running this i get a test.txt file which has following data
    Code:

    My first text file needs to have active routes details and the second one needs to have persistent routes details. the text will be varying from pc to pc. What can be a good method to split the data

    Re: Parsing of text

    The problem is that as you say the text will vary from PC to PC and as such simply using LINQ will not suffice. My advice is to try find a pattern for each point of data you need, this could be a number of spaces or knowing your information comes after a certain piece of information and then grab it using regular expressions.

    As they are a bit of an art form I couldn't just come up with one, they tend to take trial and error unless you are fairly proficient at them (Im not) but that would be the best method!
