Question

I’m testing how the classes FileStream and StreamReader work togheter. Via a Console application. I’m trying to go in a file and read the lines and print them on the console.

I’ve been able to do it with a while-loop, but I want to try it with a foreach loop.

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO;  namespace testing {     public class Program     {         public static void Main(string[] args)         {             string file = @'C:\Temp\New Folder\New Text Document.txt';             using(FileStream fs = new FileStream(file, FileMode.Open, FileAccess.Read))             {                 using(StreamReader sr = new StreamReader(fs))                 {                     foreach(string line in file)                     {                         Console.WriteLine(line);                     }                 }             }         }     } } 

The error I keep getting for this is: Cannot convert type ‘char’ to ‘string’

The while loop, which does work, looks like this:

while((line = sr.ReadLine()) != null) {     Console.WriteLine(line); } 

I’m probably overlooking something really basic, but I can’t see it.

To read all lines in New Text Document.txt:

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO;  namespace testing {     public class Program     {         public static void Main(string[] args)         {             string file = @'C:\Temp\New Folder\New Text Document.txt';             using(FileStream fs = new FileStream(file, FileMode.Open, FileAccess.Read))             {                                     using(StreamReader sr = new StreamReader(fs))                 {                     while(!sr.EndOfStream)                     {                        Console.WriteLine(sr.ReadLine());                     }                 }             }         }     } }
