插入字符串c＃6.0和Stylecop

Question

I am using Stylecop version : 4.7.49.0

Has anyone used the latest interpolate string functionality in c# 6.0

example

var totalUnits = GetUnitsGetTotalIssuedShares(myId);
var testString = $"Test Units :{totalUnits}, have been shipped.";

When I build i get the stylecop error SA0102 - because stylecop cant parse the file. It doesn't seem like there is a new version of stylecop that can handle 6.0 yet?

error :SA0102: A syntax error has been discovered in file

Is there anyway around this error?

Answer 1

SA0102 is an internal stylecop error so can't be supressed or ignored via a settings file.

You can suppress a file from stylecop by finding the filename and changing the section to this in the csproj:

<Compile Include="<filename>.cs">
  <ExcludeFromStyleCop>True</ExcludeFromStyleCop>
</Compile>

You can get the same effect by right clicking on the offending file and selecting "exclude from style cop" if you have the StyleCop plugin installed. It currently needs to be 4.7.50 alpha for Visual Studio 2015.

The more modern way of doing this is to make use of the Analyzers feature of Visual Studio 2015, with StyleCop.Analyzers .

Moving to Stylecop.Analyzers, this would add them into the rules in the relevant *.ruleset file (same place as CodeAnalysis rules)

and you can run them via

Which has the same effect as right click Run StyleCop :

Ie giving:

This will have better support for C# 6, as StyleCop 4.7.50, which Supports Visual Studio 2015, is in alpha and does not yet support C# 6.

Answer 2

StyleCop should be able to handle C# 6 now:

Changes Beta 4.7.51: Added initial (and untested) support for C# 6.0 syntax

So with stable build 4.7.54 or later you should not encounter this anymore: http://stylecop.codeplex.com/releases/view/621306
