            @MarkPflug I have a requirement to read 12 columns out of 45 - 85 total columns. This is from multiple csv files (in the hundreds). But here is the problem, a lot of the times a column or two will be missing from some csv data files. How do I check in C# for a missing column in a csv file given I use the nuget package sylvan csv reader. Here is some code:

            Looking at the source, it appears that GetOrdinal throws if the column name isn't found or is ambiguous. As such I expect you could do:

            You can check out my library Sylvan.Data.Excel. It has no external dependencies, is cross plat, open-source, MIT licensed, and also the fastest Excel data reader for .NET. It supports both .xls, .xlsx, and .xlsb all through the same API. It is not as fully featured as some other libraries, it only supports reading (not writing), but it should be a pretty direct replacement for ACE, because it implements DbDataReader. If you run into any issues/questions feel free to open them in the GitHub repo.

            Using it is pretty straightforward:

            So, I figured out that the stream is a MJPEG stream and the AVPlayer doesen't support that. Therefore it only shows the first frame.

            So I've implemented a camera service that fetches the MJPEG stream, like this:

            I believe the issue is that you are globally defining i, so outputAuthors is changing the index for outputBooks. This can easily be fixed by changing the code in both for loops to for (let i = 0 ... so that each scope has it's own variable i

            You can do it with the $event parameter. Make sure to compare your values safely.

            If your value is not in the right type or has spaces or unwanted chars, this c.state == val might not work.

            You can use the trim function to compare your value safely: c.state.trim() == val.trim()
