No Typeswitch in C#: Bogus Arguments

December 04, 2009

I just read a blog post about why there are no type-switches in C#. This is the second time I read the argument, and it still peeves me off.

A feature many programmers want in C# is the ability to switch on the type. The C# team has made the argument that it is too "hard" to implement so they didn't bother. 

Okay perhaps I am being tool harsh. Peter Hallam of the C# language design team made a more sophisticated argument here: http://blogs.msdn.com/peterhal/archive/2005/07/05/435760.aspx.

However, the thing is that I don't care for the argument. The solution seems pretty simple to me: issue errors when their is ambiguity. I mean the thing is that type resolution problem .,.
