Snippet - Read StreamReader Contents In Chunks

Here's a cool snippet I came up with to read using a StreamReader in chunks based on an input of how many lines you want to read at a time until the end of the Stream for the file.

Good example usage for where the null coalescing operator in C# comes in nicely as well :ok:

I used the fully fleged StringBuilder just in case we're dealing with a fair bit of lines based on the lnBufferCount for determining the buffer size for the string we're dealing with through the loop.

[To see links please register here]

to view this content.

Now I can read off the data from this file in chunks of linecounts of 4 in length, which enables me to deal with these string values each time through the loop, and apply my standard action to each:

Not too good with Regex, but here's an example:
