示例1: GetRefactoringsAsync

{
if (textSpan.IsEmpty)
{
return null;
}
if (String.IsNullOrWhiteSpace(document.GetText().GetSubText(textSpan).ToString())) { return null; }
var tree = (SyntaxTree)document.GetSyntaxTree(cancellationToken);
var diagnostics = tree.GetDiagnostics(cancellationToken);
if (diagnostics.Any(d => d.Severity == DiagnosticSeverity.Error || d.IsWarningAsError)) return null;
var linespan = tree.GetLocation(textSpan).GetLineSpan(false);
if (linespan.EndLinePosition.Line <= linespan.StartLinePosition.Line) return null; // single line
var semanticModel = (SemanticModel)document.GetSemanticModel(cancellationToken);

}示例2: GetSemanticDiagnosticsAsync
public async Task<System.Collections.Generic.IEnumerable<Diagnostic>> GetSemanticDiagnosticsAsync(Document document, TextSpan span, CancellationToken cancellationToken)
{

}
catch (OperationCanceledException)
{
throw; // tell Roslyn
}
catch (Exception)
{
// whatever happened, it couldn't have been that important...
// just swallow the exception and return nothing
return null;
}
if (results == null) return null;
foreach (var r in results)
{
var location = Location.Create(document.GetSyntaxTree(), r.Span);
var d = Diagnostic.Create(
id: "Clousot",
kind: "Clousot",
message: r.Message,
severity: r.Kind,
location: location
);
