2 Questions on Read Text File

[SIMIN]

Hello,

I have 2 questions:

 

1. I know I can use System.IO.File.ReadAllText() to read the contents of a text file, but that's unneccessary, I just need to read the 1st line of my text file, how can I do it?

 

2. Also, how can I get the total number of lines in my text file?

 

Thanks for your help.

FileStream and StreamReader

 

One way is to create a FileStream and then read it as text using a StreamReader:

 

using (FileStream fStream = new FileStream(fileName, FileMode.Open)) {
   //Could specify an Encoding here
   using (StreamReader reader = new StreamReader(fStream)) { 

       //Read first line
       string firstLine = reader.ReadLine();

       //Count lines - starting from the line we already read
       int lines = 1;
       while (reader.ReadLine()) {
           lines++;
       }
   }
}

 

Good luck :cool:
