Delete specific line from a text file?

Question

I need to delete an exact line from a text file but I cannot for the life of me workout how to go about doing this.

Any suggestions or examples would be greatly appr

Answer 1

One way to do it if the file is not very big is to load all the lines into an array:

string[] lines = File.ReadAllLines("filename.txt");
string[] newLines = RemoveUnnecessaryLine(lines);
File.WriteAllLines("filename.txt", newLines);
