When attempting to compile I get this message. I believe my code should compile.

This error means that the program attempted to access some memory space outside of what was allocated to it, as might happen with a bad array index.
For more specific help, make a snapshot of your workspace and post the link to it here.

6,007 PointsI don't have this in a workspace; it is part of a challenge in Querying With LINQ course. I was able to get this to compile in LinqPad.
Steven Parker
231,275 PointsDo you mean compile and run successfully? Good job, if so! Otherwise you could share your code here so we can take a look.

6,007 PointsThis is my code. It compiles in LinqPad but I have not been able to get it to run.
public static class ContainsAnyExtension { public static bool ContainsAny(this string source, IEnumerable<string> stringsToMatch) { return ContainsAny(source, stringsToMatch); } }

231,275 PointsThis method seems to call itself unconditionally, which would cause a recursion loop and would certainly explain the error you are seeing.
The instructions say that the method should "use a LINQ query". Replace the recursive call with the LINQ code you write to find the partial matches.

6,007 PointsThank you Steven, I appreciate you looking at this for me.

And happy coding!
