.txt writing help :3

[Warren1001]

Code: Select all

using (var write = new StreamWriter())
{
   write.WriteLine();
}

How would you make it remove a line..?

If you wanted to do it as you specified, do this.

Code: Select all

using(var sr = new StreamReader("path/path.txt"))
using(var sw = new StreamWriter("path/path1.txt"))
{
     string line;
        while((line=sr.ReadLine())!=null)
              {
                   if(!line.Contains("stuff in bad line"))
                {
                     sw.WriteLine(line);
                 }
               }
}
File.Delete("path/path.txt");
File.Move("path/path1.txt","path/path.txt");


So what the code does it reads every line and writes every line it reads. The if statement is used to filter out the line you dont want.
Then when it's done, it deletes the file it was reading and moves the file that it was writing to to the one it was reading.

You possibly forgot this:

Code: Select all

using System.IO;
