.NET: C# find pattern in byte array

Byte Arrays are not as easily handled as strings when it comes to finding what they contain, especially if we are searching for a pattern of matching bytes.
It seems like everyone is rolling their own on this one. Most examples I have seen look at converting bytes to strings and then using IndexOf operators.
However, if you use bytes that cannot be converted to a string easily or do not want to use string comparison here is my version of a working function that does the trick.

private static int ByteSearch(byte[] searchIn, byte[] searchBytes, int start = 0)
{
    int found = -1;
    bool matched = false;
    //only look at this if we have a populated search array and search bytes with a sensible start
    if (searchIn.Length > 0 && searchBytes.Length > 0 && start <= (searchIn.Length - searchBytes.Length) && searchIn.Length >= searchBytes.Length)
    {
        //iterate through the array to be searched
        for (int i = start; i <= searchIn.Length - searchBytes.Length; i++)
        {
            //if the start bytes match we will start comparing all other bytes
            if (searchIn[i] == searchBytes[0])
            {
                if (searchIn.Length > 1)
                {
                    //multiple bytes to be searched we have to compare byte by byte
                    matched = true;
                    for (int y = 1; y <= searchBytes.Length - 1; y++)
                    {
                        if (searchIn[i + y] != searchBytes[y])
                        {
                            matched = false;
                            break;
                        }
                    }
                    //everything matched up
                    if (matched)
                    {
                        found = i;
                        break;
                    }
 
                }
                else
                {
                    //search byte is only one bit nothing else to do
                    found = i;
                    break; //stop the loop
                }
 
            }
        }
 
    }
    return found;
}

CF: ColdFusion Report Builder migration errors with Invalid construct.A script statement must end with ";"

You may had the opportunity to work with ColdFusion Report Builder in the past. It was a cool little tool that we used with ColdFusion 7 when you could not afford anything else to write reports with.
In its first iteration it was pretty buggy; today, it still is around but I see fewer people using or mentioning it. It barely gets any play at the user conferences and is treated more like a red-headed step child (I have nothing against red headed people of any kind ;o).
In my opinion it is still a useful tool that does not get its share of attention. However, when you migrate from older versions of reports that you have written with, say, ColdFusion Report Builder (CFRB) 7, to ColdFusion Report Builder 8 or 9 you may get some fairly unexpected errors.
Such as this:

Invalid construct.A script statement must end with ";"

The only thing you did it just open and save the report. No changes were actually made. All of a sudden, errors jump up from seemingly nowhere. Well, for me, that resulted in many hours of ghost hunting (since I cannot see what's in the cfr files) until I finally got the bright idea to dig up an old copy of Report Writer 7 for those reports.

I restored the .cfr file from backup, made a change using CFRB 7 and everything worked. Just to check for sanity, I, then, restored the file again, made a simple change using either CFRB 8 or 9 and, boom, broken again.

The lesson here is to make sure you ask before you touch a ColdFusion report (.cfr) file with which version of ColdFusion/ColdFusion Report Builder it was created. Then, make the modifications only with that tool.

This in the end may save you many hours of frustration.

Cheers,
B.
