Another Problem in C#!

Question

I want to move lines in a text file!
Is there a method that I can use!
I used replace to replace strings in file, but I want to move the whole line o text to another position in the file!

Answer 1

Try this (swap lines 4 - 5):

string[] lines = File.ReadAllLines("file.txt");
string tmp = lines[4];
lines[4] = lines[5];
lines[5] = tmp;
File.WriteAllLines("file.txt", lines);
