LINQPad strange bug

NetMage

The following code causes an Object reference not set to an instance of an object in LINQPad, but works in VS 2017:

var anObjectList = new List { "name", new[,] { { 1 } } };

Console.Write("Length ");
Console.WriteLine(anObjectList.Count());
Console.WriteLine(anObjectList[1]);

This code doesn't compile for me (in either linqpad or VS). I get "CS0305 Using the generic type 'List' requires 1 type arguments"

It looks like you're trying to create a list of anonymous type. I don't think that works. Try this instead.

var anObjectList = new[] { o, o1 }.ToList();

Sorry, the post got mangled by the comment editor - trying again for the first line:

var anObjectList = new List<object> { "name", new[,] { { 1 } } };

Works fine for me. What version of LINQPad are you using?

NetMage

LINQPad 5.26.01 AnyCPU and x86. When I disabled My Extensions it works, so something must be happening there, but I have a LOT of extensions. I will have to try to narrow it down.

NetMage

When I added all the imports and My Extensions to the query it still works, so now it is a little trickier...

NetMage

I found it - I had a ToDump() on object in My Extensions that reformatted 2D arrays improperly. I didn't realize Console.WriteLine would call ToDump.

Sorry - never mind!
