If statement pertaining to database criteria

I am brand new to this community. I am also somewhat new to programming and this is a noob question. If my wording is bad or any members have any advice to give a newbie please do! Anyway, here I go!

The following method (although its obvious), grabs a file and inserts it into a database table (KC_Reply_Shipped), (or cancels into another table), also obvious. The file looks something like this

YYYY847583 blahblahblah blah blahahasdf blah blah

XXX8343445 " " " "

XXX8976556 " " " "

However, I do NOT want to insert the YYYY. I can not help that the File has this, because it is out of my control. But I DO want the XXX. Sometimes the file will have YYYY and sometimes it will not.

although this seems so easy, me being noob, I get confused on the wording because I already have a while statement and the method is boolean. FYI this is only for fun and experimentation. Nothing serious. Any help or answer would be greatly appreciated. Thank you^2 in advance!

    private bool InsertIntoDatabase(FileInfo file)
    {
        string table = "KC_Reply_Shipped";
        string line;
        StreamReader reader = new StreamReader(file.FullName);
        try
        {
            Database db = new Database();
            ShippedOrders = new List<string[]>();
            CancelledOrders = new List<string[]>();
            while ((line = reader.ReadLine()) != null)
            {
                string[] temp = GetFileDataForInsert(line);
                temp[temp.Length - 1] = file.Name.Substring(0, file.Name.Length - 4);
                if (temp[1] == "30")
                {
                    table = "KC_Reply_Cancelled";
                    CancelledOrders.Add(temp);
                    db.UpdateOrderToCancelled(temp[0]);
                }
                else
    开发者_StackOverflow            {
                    ShippedOrders.Add(temp);
                    db.UpdateOrderToShipped(temp[0]);
                    db.UpdateOrderTrackingNumber(temp[10]);
                    db.UpdateOrderNotes(temp);
                }
                db.BatchInsert(table, temp);
            }
        }
        catch (Exception e)
        {
            errorMsg = e.Message;
            return false;
        }
        finally
        {
            reader.Close();
        }
        return true;
    }

You could try something like the following to check the start of the line and the make a decision from there:

if(!line.StartsWith("YYYY"))
{
     //....do stuff here
}

You can skip the lines starting with YYYY like this:

...

while ((line = reader.ReadLine()) != null)
{
    if (line.StartsWith("YYYY"))
        continue;
    else {
        // your code
    }
}

...

If you want to ignore the file in case there is a "YYYY" then you can do this:

...

while ((line = reader.ReadLine()) != null)
{
    if (line.StartsWith("YYYY"))
        return true; // or false, whatever you method should return in this case
    else {
        // your code
    }
}

...
