CodeFactor: Duplicated code for argument completions attribute class #7724
Description
The following attribute class can be found in several code files. CodeFactor found this as duplicated code and grades this as a severe issue.
[ArgumentCompletions(
EncodingConversion.Ascii,
EncodingConversion.BigEndianUnicode,
EncodingConversion.OEM,
EncodingConversion.Unicode,
EncodingConversion.Utf7,
EncodingConversion.Utf8,
EncodingConversion.Utf8Bom,
EncodingConversion.Utf8NoBom,
EncodingConversion.Utf32
)]found in

The CodeFactor grading could improve for each of the mentioned code files if the attribute class would be replaced by a single attribute class dedicated for the Encoding Conversion argument completion.
e.g.
[ArgumentEncodingConversionCompletions]in lieu of the above. This would be similar to the [ArgumentToEncodingTransformationAttribute] which consolidates the function to transform the properties from a string to the correct encoding enum.
Furthermore a centrally defined attribute for the Encoding completion would prevent mistakes if another encoding is added in the future.
