It appears this statement produces a value that displays at the command line when the statement executes. This is usually undesirable in functions, because someone else calling the function might not expect or need the output. Sometimes (usually due to overloading), Code Analyzer is incorrect and the expression produces no output.

Because there is little harm in putting a semicolon after the statement even if the statement does not result in displaying output, use the context menu to add a semicolon. If the message is incorrect, suppress it as described in Adjust Code Analyzer Message Indicators and Messages.
