I want to read one line of a text file, one character at a time. I figure it'd be something like this:

```
string[] acct = File.ReadAllLines(Environment.GetFolderPath(Environment.SpecialFolder.Desktop) + @"\Accts.txt");
for (int i = 0; i >= acct[line].Length; i++)
{

}

```

But I don't know what goes in the for loop. I want to read each character, and if it's a specific character have it do something else.
