Bug in the File.ReadLines(..) method of the .net framework 4.0

Question

This code :

IEnumerable lines = File.ReadLines(\"file path\");
foreach (var line in lines)
{
    Console.WriteLine(line); 
}
foreach (var line          


        

Answer 1

If you need to access the lines twice you can always buffer them into a List

using System.Linq;

List lines = File.ReadLines("file path").ToList(); 
foreach (var line in lines) 
{ 
    Console.WriteLine(line);  
} 
foreach (var line in lines) 
{  
    Console.WriteLine(line);  
}
