Make codeattributeargument code generation use a : in C#

Question

0.00/5 (No votes)

See more:

I have code to generate code that includes generating attributes with parameters.

The code is e.g.:

VB.NET

Public Shared Function ParameterisedAttribute(ByVal AttributeName As String,
                                              ByVal parameters As IList(Of CodeAttributeArgument)
                                              ) As CodeAttributeDeclaration



    If parameters IsNot Nothing Then
        Return New CodeAttributeDeclaration(AttributeName, parameters.ToArray())
    Else
        Return New CodeAttributeDeclaration(AttributeName)
    End If


End Function

But if I codegen this to C# code it incorrectly uses an equals sign instead of a colon to name the parameter e.g.

C#

[CQRSAzure.EventSourcing.DomainNameAttribute(domainNameIn="Accounts")]

which should be

C#

[CQRSAzure.EventSourcing.DomainNameAttribute(domainNameIn:"Accounts")]

What I have tried:

The code as above... no other ideas.

I've never seen a colon used as an operator in an attribute (is this yet another useless new feature in the latest iteration of C#?), but the equal sign IS most definitely valid, and assuming the rest of the attribute reference is also valid, it should compile with no problems.

Bizarre but it definitely demands a colon in VS2015 / .NET 4.6.2
If I hover over it the parameter name is suggested but it puts the colon in.

Shall raise defect report with MS

Try changing the targeted framework in the project using the attribute to 4.5 and see if it still wants a colon.

Yup - even 4.0 demands a colon for the named argument - https://msdn.microsoft.com/en-us/library/dd264739.aspx
