c# - Read txt file from line to line to list?

Question

need some function that will return List with lines of txt file (ex. from 10 line to 25 line). Any solutions? All my tries met with failure.

Answer 1

You can use LINQ and File.ReadLines which enumerates over file lines (internally it uses StreamReader):

List<string> lines = File.ReadLines(path).ToList();

Answer 2

You could do:

List<string> fileLines = new List<string>();

using (var reader = new StreamReader(fileName))
{
    string line;
    while ((line = r.ReadLine()) != null)
    {
       fileLines.Add(line);
    }
}

Answer 3

// Retrieve 10 lines from Somefile.txt, starting from line 1
string filePath = "C:\\Somefile.txt";
int startLine = 1;
int lineCount = 10;
var fileLines = System.IO.File.ReadAllLines(filePath)
                .Skip((startLine-1))
                .Take(lineCount);

Answer 4

List<string> lines = File.ReadLines().ToList();
for(int i = 0; i < lines.Count; i++){
if( i >= startline && i <= endline) LinesFromStartToEnd.Add( lines[i] );// same string list
}

Answer 5

If your file isn't too large you can do it with linq:

int start = 10;
int end = 25;    
List<string> lines = File.ReadLines(path).Skip(start - 1).Take(end - start + 1).ToList();
