I have to read lines from a text file in sequential order. The file is a custom text format that contains sections. If some sections are out of order, I would like to look for the starting of the next valid section and continue processing.

Currently, I have some code that looks like this:

for (int currentLineIndex=0; currentLineIndex < lines.Count; currentLineIndex++ )
{
    //Process section here
    if( out_of_order_condition )
    {
        currentLineIndex--;//Stay on the same line in the next iteration because this line may be the start of a valid section.
       continue;
    }
}

Is this code smell?
