Re: Console.WriteLine(s) Is Missing Line Terminator?

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

I thought they recommend the & operator for concatenating
strings in VB over the + operator.

When outputting strings, you could try using FormatString
instead.

Console.WriteLine(String.Format("Level = {0}, InfoString = {1}", _
Level, InfoString))

Huh? Can you give an example of that? And what do you suggest we use
instead? Hopefully not the + operator.

*Hopefully* not the + operator? I'm interested to know why you say that,
so
please let me know if I'm missing something :)

The '&' concatenation performs runtime casting of objects to strings, so
it
always calls the default ToString() method. It is better to perform this
cast implicitly at design time so you can also specify the format if
needed
by calling an integer's ToString method.
Yes, in VB6 it was slower to join strings with '+', but in VB.Net all
strings are internally joined this way anyway.

It's only in there for VB6 style compatibility,

No it certainly isn't.

OK, fire away Mattias, I am genuinely interested.

Cheers,
