示例1: ReportDiagnostics
private static void ReportDiagnostics(
SyntaxNodeAnalysisContext syntaxContext,
StatementSyntax firstStatement,
IfStatementSyntax ifStatement,
ExpressionStatementSyntax expressionStatement,
DiagnosticSeverity severity,
List<Location> additionalLocations,
string kind)
{
var tree = syntaxContext.Node.SyntaxTree;
var properties = ImmutableDictionary<string, string>.Empty.Add(
Constants.Kind, kind);
var previousToken = expressionStatement.GetFirstToken().GetPreviousToken();
var nextToken = expressionStatement.GetLastToken().GetNextToken();
// Fade out the code up to the expression statement.
syntaxContext.ReportDiagnostic(Diagnostic.Create(s_unnecessaryDescriptor,
Location.Create(tree, TextSpan.FromBounds(firstStatement.SpanStart, previousToken.Span.End)),
additionalLocations, properties));
// Put a diagnostic with the appropriate severity on the expression-statement itself.
syntaxContext.ReportDiagnostic(Diagnostic.Create(CreateDescriptor(severity),
expressionStatement.GetLocation(),
additionalLocations, properties));
// If the if-statement extends past the expression statement, then fade out the rest.
if (nextToken.Span.Start < ifStatement.Span.End)
{
syntaxContext.ReportDiagnostic(Diagnostic.Create(s_unnecessaryDescriptor,
Location.Create(tree, TextSpan.FromBounds(nextToken.Span.Start, ifStatement.Span.End)),
