Using "fscan" Equivalent in C#

[marathoner]

I would like to read the following entries of mixed data types from a ascii
text file using C#. This can be easily performed in C using fscanf. Is
there an equivalent function in C#?
1 2 1201 1 -0.4175970000000 00D+06 0.1296000000000 00D+06
0.0 0.7530000000000 00D+03 0.1988000000000 00D+04

No, there is not the same method as fscanf.
You need to read the line and use pattern matching to parse line on types

wouldn't' it be good if such task could be done simpler?

People who have been around C and C++ who know about the wonders of >>
operators and scanfs find it hard to believe there is not a similar,
easy facility in Java and C#. There are a lot of small projects that
simulate it as best as possible. I would recommend a search on
CodeProject.

Is a regular expression + TextReader.Read Line really so hard?

Actually, C# does have bit-shifting, even using the same operator ;)

If you're not too concerned about parse errors (e.g. willing to accept exceptions),
this could be done like this:

double[] numbers = Array.ConvertAl l(RegEx.Split(l ine, "\\s+")), Double.Parse);

Hello Jon Skeet [C# MVP],

It seems very crazy after F# pattern matching/active pattern features , isn't
it ;)

How would you use regular expression?

Use the regex to capture the appropriate groups (if it's not as simple
as just splitting by a common delimiter - if it is, that's fine) and
then int.Parse etc to convert those group values into the types you
need.

If you can get away with just using string.Split and then parsing each
part separately, so much the better :)
