BTW, this is really useful in conjunction with Excel parsing since users may tack on a row down the page thousands of lines with no regard to how that affects parsing the data. In the same class, I put any other helpers I found useful, like parsers so that if the field contains text that you know should be a number, you can parse it fluently.

Minor pro tip for anyone new to the idea. Anyone at SO, really? Now you have another useful helper, IsNullEquivalent which can be used in this context and any other, too. I know this has been answered already and it's an old question, but here's an extension method to do the same:.

IsNotEmpty cell would be your own implementation, checking whether the data is null or empty, based on what type of data is in the cell. If it's a simple string, it could end up looking something like this:. Still, it essentially checks each cell for emptiness, and lets you know whether all cells in the row are empty.

AFAIK, there is no method that does this in the framework. Even if there was support for something like this in the framework, it would essentially be doing the same thing. And that would be looking at each cell in the DataRow to see if it is empty. Privacy policy.
