Code

var skip = false;

foreach (var line in lines)
{
    if (line == "[start]" || line == "[finish]")
        skip = !skip;

        continue;

}

You could also index the start and finish points and interest them into a standard for loop.

If [start] is meant to only indicate the start of the ignore phase, your logic would trigger an unignore if a duplicate [start] tag was found when you may only want to start that unignore flag when you see the [end] tag. Any assumptions past this however, becomes a fine line bordering on the premise of "uneducated guesswork" given the limited amount of details provided by OP, so I'll only add this as a mention for now.

As pseudocode this is a clear representation though.

Code

bool skip = false;

foreach (var line in lines)
{
    if (line.Equals("[start]", StringComparison.Ordinal))
    {
        skip = true;
    }
    else if (line.Equals("[finish]", StringComparison.Ordinal))
    {
        skip = true;
    }
    else if (!skip)
    {
        // relevant data
    }
}
