Free C# Class – iliPing – Threadable, Fast, No External Classes Required

August 23rd, 2010 No comments

Before I give you another free C# class, I thought I may pass along a bit of a ProTip: it seems to me that the easiest money I make is from TextLinkAds. TLA capitalizes on the fact that spiders at least visit your site, even if real humans don’t. Join and give it a try.

This is a good class, and works well if you thread it. It works without using any other XML-RPC classes externally, and the only site it doesn’t work for me is sites that use nonstandard XML-RPC parameters like autopinger. I usually set it up to just go through a list of sites/blogs with their titles, and a list of XML-RPC ping service URI’s. I also thread this, and can ping quite quickly. This should be compatible with both .NET Framework, and my personal favorite, Mono (check out MonoDevelop sometime!).

Feel free to use this however and modify it…if you make any changes, please pay it forward and share them with everyone else so they can use the improvements too, since this is opensource.
