How do I set formatting rules for each clause in linq query syntax to appear on a new line

Hi,

I use StyleCop, which includes a readability rule (http://stylecop.soyuz5.com/SA1103.html) stating that all clauses in a linq query must appear on the same line, or on a new line.

I run into problems when I use a grouping in query syntax.

var result =
                    (from c in collection
                     where c.SomeProperty == true
                     group c by c.SomeOtherProperty
                     into grp select grp.OrderByDescending(c => c.AnotherProperty).First()).ToList();

I cannot find a way to make R# put the "into" and "select" clauses on a seperate line.

Hello Tim,

There's a corresponding option in C# Formatter Settings. I've attached an image for a reference.

Thanks.

Hi Alex,

This option does not make a difference for me. The actual linq query is quite long with multiple from and where conditions, so whether the option you provided is ticked or not, the formatting comes out the same.

The issue seems to be specifcally related to using an "into" clause in a linq query. After the into, multiple other clauses are then placed on the same line.

Here is another example. I cannot get the line with "into" the format correctly:

foreach (var rateEntry in from originCode in originCodes

from destinationCode in destinationCodes

from transportModes in transportModeGroups

from containerType in containerTypes

from serviceProvider in serviceProviders

from commodity in commodities

select (from re in rateEntries

where

re.OriginCode == originCode &&

(re.DestinationCode == destinationCode ||

(string.IsNullOrEmpty(re.DestinationCode) && string.IsNullOrEmpty(destinationCode))) &&

transportModes.Contains(re.Mode) &&

(re.ContainerType == containerType || (string.IsNullOrEmpty(re.ContainerType) && string.IsNullOrEmpty(containerType))) &&

(re.ServiceProviderDatabaseKey == serviceProvider || (re.ServiceProviderDatabaseKey == null && serviceProvider == null)) &&

(re.CommodityCode == commodity || (string.IsNullOrEmpty(re.CommodityCode) && string.IsNullOrEmpty(commodity)))

select re).SingleOrDefault()

into rateEntry where rateEntry != null select rateEntry)

rateLines.AddRange(rateEntry.RateLines.Where(rl => rateLines.All(rl2 => rl2.ChargeCode != rl.ChargeCode)));

Tim,

Our forum engine trimmed the code and line breaks.
Could you please attach a *.cs file with the actuall formatting with example how the code is formatted by R# and how'd you like it to be formatted? This will be much appreciated.

Thanks in advance!

Hi Alex,

It looks fine on my browser?

I would like to know how to format this following query:

from c in collection
where c.SomeProperty == true
group c by c.SomeOtherProperty
into grp select grp

To:

from c in collection
where c.SomeProperty == true
group c by c.SomeOtherProperty
into grp
select grp

Or maybe to:

from c in collection
where c.SomeProperty == true
group c by c.SomeOtherProperty into grp
select grp

Hi Tim,

I've checked that out, and it looks like there's no such option in ReSharper Formatter for now.

We apologize for the inconvenience.
Thanks.
