Question

I want to throw exception with additional data without creating exception variable. Something like this:

throw new Exception() { Data.Add("foo", "bar") };

Is it possible?

Answer 1

It looks like you should be able to do that with:

throw new Exception { Data = { { "foo", "bar" } } };

(Assuming you’re using C# 3, which has collection initializers…)

Of course you can do this in conjunction with constructor arguments:

throw new ArgumentException("paramName") { Data = { { "foo", "bar" } } };
